Lethal rupture of an echinococcal cyst of the liver

A 50-year-old man is admitted to the hospital emergency service because of a 24-hour history of right abdominal pain. Ultrasound examination and laboratory tests suggest the perforation of an Echinococcal cyst situated in the subcapsular area of the right hepatic lobe. The patient and his family refuse the recommended hospitalisation and operation and leave the hospital on their own responsibility. 60 hours later the patient dies. Post-mortem examination confirms the diagnosis of a perforated hydatid cyst of the right hepatic lobe. The cause of death was a partly fibrino-purulent, partly nodular peritonitis including the area of liver rupture.     

Cerebral hydatid cysts in children.

A parasitic tapeworm, called Taneia Echinococcus, causes hydatid disease. Hydatid disease is endemic in sheep and cattle-raising areas of the world. Hydatid disease of the central nervous system constitutes 2%-3% of all reported cases of hydatid cysts. In our institution, 23 children underwent surgery for intracranial hydatid cysts between 1979 and 1995. There were 14 boys and 9 girls, aged between 3 to 16 years (mean 8.8 years). Signs and symptoms were related to the site and size of the cyst. Headache and vomiting due to increased intracranial pressure were the most common presenting symptoms. A round cystic lesion without perifocal edema and rim enhancement is the characteristic appearance on a computed tomography (CT) scan. A magnetic resonance image visualizes cyst location better than CT. Associated systemic hydatidosis in four of our patients involved kidney, liver, lung, and liver and lung, respectively. Intact cyst removal was achieved in 14 patients. In three patients with infected or inflamed hydatid disease, the ruptured cyst capsule was totally resected. Aspiration and extirpation were performed in only one patient. Eleven patients were treated with chemotherapeutic agents such as albendazole or mebendazole due to cyst rupture during surgery or associated systemic hydatid disease. Hydatid disease can also be seen in Western countries because of travel and migration. Cerebral hydatid cyst should be kept in mind for the differential diagnosis of cystic lesions.     

Spontaneous rupture of hydatid cyst due to strain-defecation

We report a case of strain-induced spontaneous rupture of hydatid cyst. Hydatid cyst rupture was diagnosed in a 19-year-old girl who presented with swelling and pain in the the right upper quadrant of sudden onset after straining for defecation.     

Ruptured pulmonary hydatid cyst with anaphylactic shock and pneumothorax

Hydatid cyst is a disease caused by a parasitic tapeworm, Echinococcus granulosus, and most commonly involves liver and lung. Ruptured pulmonary hydatid cyst can present a diagnostic challenge, and radiograph can be inconclusive. Anaphylactic reaction is a rare complication of ruptured pulmonary hydatid cyst. A 22-year-old male came to our emergency department in shock with symptoms of shortness of breath and altered mental status from the previous day. Radiograph showed a thin-walled circular translucent area in the right upper lung field, which was misdiagnosed as pneumothorax, and an intercostal chest tube was inserted. After 5 days, repeat radiograph revealed a cavity with an air/fluid level. The chest tube was removed and contrast-enhanced computed tomogram showed a cavity with water-lily sign, which suggests ruptured hydatid cyst. Immunoglobin-G enzyme-linked immunosorbent assay for Echinococcus was positive. The patient responded well to treatment with crystalloid infusion, supplemental oxygen, and albendazole, and then underwent surgery. Anaphylactic reaction due to rupture of a hydatid cyst is rare, but hydatid disease should be suspected in patients from areas where Echinococcus is endemic.     

Sonographic spectrum of hydatid disease

Hydatid disease, caused by Echinococcus granulosus, is a parasitic disease that is endemic in many parts of the world. Hydatid cyst demonstrates a variety of imaging features, varying according to growth stage, associated complications, and affected tissue. The radiologic findings range from purely cystic lesions to a completely solid appearance. Ultrasound is the most important imaging modality for liver hydatid disease and clearly demonstrates the floating membranes, daughter cysts, and hydatid sand characteristically seen in purely cystic lesions. The radiologist's familiarity with the imaging findings of the disease is very important for earlier diagnosis and an appropriate treatment. There are several classification schemes for liver hydatid cysts based on their ultrasound appearances; the initial classification by Gharbi et al and the World Health Organization classification are the most commonly preferred. Computed tomography and magnetic resonance imaging play a key role in recognizing the complications such as rupture and infection of cysts associated with hydatid disease. Today, percutaneous treatment of liver hydatid cysts, a safe, easily applicable, and well-tolerated method, has become the most effective and reliable treatment procedure in most cases if the hydatid cyst is viable. In patients treated with the percutaneous treatment technique, a decrease in the dimensions of the cyst, solidification of the cyst contents, and irregularity in the walls of cysts are signs suggestive of cure. The radiologist should also be familiar with the postoperative follow-up ultrasound findings of hydatid cyst to prevent misinterpretation of the hypoechoic, anechoic, or hyperechoic appearance of posttreatment hydatid disease appearance as recurrence.     

Sonography of multifocal hydatidosis involving lung and liver in a female child

Hydatid disease, caused by Echinococcus granulosus, is a zoonotic infection encountered worldwide. Though involvement of the liver and lungs is quite common, pelvic involvement is rarely reported, with the incidence being 0.2–2.2 %. Ovarian and broad ligament hydatids are rare entities and are usually seen after rupture of a hepatic hydatid cyst. These cysts are usually asymptomatic, and a high index of clinical suspicion coupled with unequivocal imaging findings is required to make an accurate and timely diagnosis. We present a case of multifocal hydatid disease in a female child involving the lungs and liver and provide an account of the quintessential radiological findings.     

An unusual cause of chest pain: An isolated huge cardiac hydatid cyst

Hydatid disease is a human parasitic infection caused by the larval stage of Echinococcus granulosus. The most common locations for hydatid cysts are the liver and lungs. Cardiac involvement is rare, and isolated cardiac hydatid cysts are even more unusual. We report the case a 48‐year‐old female patient with an isolated huge cardiac hydatid cyst involving both the left ventricular free wall and the pericardium, and presenting with atypical chest pain. © 2017 Wiley Periodicals, Inc.

Co-Occurrence of Diaphragmatic and Serratus Anterior Muscle Hydatidosis: An Unusual Localization

Background: With hydatid cyst, the skeletal muscles and diaphragm are rarely affected, and hepatic and pulmonary hydatid cysts are far more common. We report a case with an unusual localization of diaphragmatic and serratus muscle anterior hydatidosis that occurred simultaneously. Case Report: A 37-year-old developmentally disabled woman presented to the Emergency Department (ED) of Harran University with tachycardia, tachypnea, and dyspnea. On pulmonary auscultation, breath sounds were decreased on the right side. A chest X-ray study revealed a radiopaque right hemithorax with a mediastinal shift and tracheal displacement. Thoracic computed tomography scan revealed a hydatid cyst in the serratus muscle anterior and cystic vesicles in the pleural cavity. The patient underwent chest drainage. During drainage, daughter vesicles within the pus were detected macroscopically. An elective thoracotomy was performed after hemodynamic stabilization of the patient. Postoperative chest X-ray study demonstrated that the lungs had re-expanded. The patient had no postoperative complications and was discharged with relief of all symptoms. Conclusion: Hydatid cyst should be considered, especially in endemic regions, in the differential diagnosis in the presence of a rare localization or unexpected clinical presentation. Surgical intervention is the appropriate approach for the treatment of hydatid cyst when there is concomitant intrathoracic involvement.     

The role of endoscopic retrograde cholangiopancreatography in the management of hepatic hydatid disease.

BACKGROUND AND STUDY AIMS: Hydatid disease of the liver, and its complications, causes serious morbidity and mortality. We evaluated the role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of hepatic hydatid disease. PATIENTS AND METHODS: This retrospective analysis includes 28 patients with hepatic hydatid disease who underwent ERCP. ERCP was performed preoperatively in 11 patients, for acute cholangitis (n =7), acute pancreatitis (n = 1) and right upper quadrant pain (n = 3), and in eight asymptomatic cases to search for fistulae between the cyst and the biliary tree. In a further nine patients ERCP was performed for early (< 30 days; n = 7) and late (n = 2) postoperative biliopancreatic problems. RESULTS: In all seven patients with cholangitis preoperative ERCP with EST and ductal clearance of daughter cysts and debris led to substantial clinical improvement, including four acutely ill elderly patients who stabilized and were later able to undergo surgery. EST in two of the three patients with pain who had papillary stenosis led to resolution of the abdominal pain. Six of the seven postoperative fistulae could be successfully treated endoscopically using EST. CONCLUSIONS: This study demonstrates the usefulness of ERCP in symptomatic patients with hepatic hydatid cysts; EST enables clearance of the common bile duct and allows healing of postoperative fistulae in the majority of patients. We do not, however, recommend performing routine preoperative ERCP in asymptomatic patients with the disease.     

Ventricular Tachycardia and the Cystic Heart: A Case Report

BackgroundHydatid cysts are caused by Echinococcus granulosus infection, and hydatidosis is recognized as a re-emerging zoonotic disease globally. While the liver is the most commonly affected organ, other organs can also be affected, including the heart. Because of the low sensitivity and specificity of serologic diagnostic tests, ultrasound and echocardiography are increasingly used to make the diagnosis of cardiac hydatid cyst.Case reportWe report the case of a cardiac hydatid cyst, detected by point-of-care ultrasound (POCUS), in a 79-year-old woman who presented with shortness of breath and was in ventricular tachycardia. The diagnosis was further confirmed with a computed tomography scan. Although cases of alveolar and liver hydatid cysts are seen, this is the first case of a cardiac hydatid cyst in Bhutan.Why Should an Emergency Physician Be Aware of This?This case illustrates the importance of POCUS in reaching a diagnosis, particularly in resource-poor areas where other sophisticated diagnostic tools are not easily available. A cardiac hydatid cyst must be in the differential for structural causes of dysrhythmias. This is especially so because treatment of unstable dysrhythmias in the acute setting of an emergency department has to be modified from the usual algorithm in the presence of a cardiac hydatid cyst, due to the potentially fatal risk of cyst rupture and anaphylaxis.     

Pulmonary Mucormycosis and hydatid cyst: A case report

Mucormycosis is a group of life‐threatening diseases caused by a fungus of the Mucoraceae family and has a higher mortality rate compared with other known fungal infections. Hydatid cyst, caused by Echinococcus, is a crucial health concern in endemic areas and the disease is characterized by slow‐growing cysts in the liver, lungs, or other organs. In this report, a woman with coexistence of hydatid cyst and Mucormycosis is introduced. The patient was a 52‐year‐old woman with approximately 6 years'' history of uncontrolled diabetes mellitus and hypothyroidism, who presented with cough, sputum, and dyspnea 2 months ago. On the initial auscultation of the lungs, there was a decreased sound at the base of the left lung, and she had a fever. In blood tests, she had a high titer of erythrocyte sedimentation rate and 3+ C‐Reactive Protein. The symptoms in favor of hydatid cyst were observed in lung computed tomography and in pleural needle biopsy, hydatid cyst was confirmed. With this indication, she underwent wedge resection, and resection of the left lower lung cyst. Two samples are taken from the cyst side and the pathology report was consistent with Mucormycosis (wide filaments with a 90‐degree angle). The patient was immediately treated with liposomal amphotericin for 4 weeks. The Lung CT scan was performed before and after treatment. Albendazole was treated to treat hydatid cyst. After discharge, the treatment of the patient continued with oral Posaconazole, and after the treatment finalization, the general condition of the patient was good, and she did not have any complaints. In pulmonary diseases that do not respond significantly to surgical treatment (such as hydatid cyst), fungal disease (mucor) must be considered simultaneously. Mucormycosis is more prevalent in patients with uncontrolled diabetes, and it is necessary to be considered if these patients were infected with pneumonia and their symptoms did not improve with usual treatments.     

Kyste hydatique pelvien : une localisation rare

Hydatid disease is common in North Africa countries. It often affects liver and lung. Pelvic location is exceptional. Ultrasound and computed tomography are helpful for the diagnosis. We report a case of 33-year-old man with a pararectal hydatid cyst, presenting with rectal tensemus, urinary symptoms and neurological disorders.     

Incidentally detected hydatid cyst of the adrenal gland: A case report

Hydatid cysts are a zoonotic disease that can involve many organs and tissues in the human body but primarily involve the liver and lungs. Of the main organs, adrenal glands are those seldom affected by hydatid cysts. The purpose of this study was to present a case with an incidentally detected hydatid cyst of the right adrenal gland on computed tomography, and a positive echincoccus IgG enzyme-linked immunosorbent assay test on top of a toxic multinodular thyroid goiter for which thyroidectomy was indicated.     

Kyste hydatique primitif de la cuisse révélé par une cruralgie. À propos d’un cas

Hydatid echinococcosis is preferentially localized in the liver. Muscular localization of hydatid cyst is an uncommon event. Symptoms are often discrete. Diagnosis is confirmed by the imaging: ultrasonography and/or magnetic resonance imaging, thus avoiding any untimely gesture. The treatment is surgical. The authors report a case of primary and isolated localization of a muscular hydatid cyst of the thigh in a sport woman revealed by cruralgia.     

Surgical treatment of hepatic hydatid cyst

Hydatid disease of the liver is caused by the tapeworm Echinococcus granulosus, and the highest incidence of human infestation occurs in sheep and cattle-raising areas. Although, still an uncommon occurrence, it is being seen with increasing frequency; hence, it is important that surgeons make themselves aware of the pathology and treatment of the disease. The liver is most commonly involved, although many other organs, including lungs and brain may also be affected. An echinococcal cyst of the liver was reported in a patient who is a resident in Northern Ireland but had originally lived and worked in mainland Britain. Details of the lifecycle, pathology, diagnostic techniques and surgical management of hydatid cysts are reviewed.     

Segmental portal hypertension due to a splenic Echinococcus cyst.

A 60-year-old Libyan woman developed perihilar splenic varices without other signs of portal hypertension. Plain abdominal X-ray examination showed two calcified structures in the left and right hypochondria. Ultrasound examination disclosed a 3-cm diameter, globally calcified hydatid cyst lodged in a critical location at the hilar region of the spleen. The cyst was compressing the hilar vessels which resulted in dilatation and varix formation. Another hydatid cyst measuring 5 cm in diameter, with extensive wall calcification was visualized in the right lobe of the liver. The splenic size was within normal limits. The liver revealed normal texture and size and the portal vein was of normal caliber. The patient underwent an uneventful splenectomy and was well at discharge.     

Diverse presentation of spontaneous rupture of urinary bladder: review of two cases and literature

The objective of the study was to highlight diagnostic dilemmas and suggest pointers toward early diagnosis of spontaneous rupture of urinary bladder based on case study of 2 patients diagnosed as a case of spontaneous rupture of urinary bladder. A 26-year-old man presented with painless progressive abdominal distension of 1-week duration. In absence of acute abdominal symptoms and signs, the diagnosis of chronic liver disease with ascites was entertained. Peritoneal fluid aspirate demonstrated high urea and creatinine levels. Computed tomographic (CT) scan of abdomen suggested urinary bladder rupture, which was further confirmed by CT cystogram. Another 34-year-old man presented with acute abdominal pain, hematuria, and features of peritonitis. There was no history of trauma. Foley catheterization revealed blood-stained urine. Ultrasonography abdomen suggested urinary bladder rupture, which was again confirmed by CT cystogram. Both patients made uneventful recovery after repair of bladder perforation. Spontaneous rupture of urinary bladder is extremely rare with only very few reports available in literature. High creatinine levels in the peritoneal fluid aspirate of the first patient and the blood-stained urine in the second patient were pointers toward possibility of urinary bladder rupture. Rupture of urinary bladder should always be considered in differential diagnosis of patients presenting with free fluid in abdomen/peritonitis, decreased urine output, hematuria and in whom increased level of urea/creatinine are detected in serum and/ or peitoneal fluid aspirate.     

Polycystic liver disease with obstructive jaundice: Treatment with ultrasound-guided cyst aspiration

A 59-year-old woman with polycystic liver (PCLD) and kidney disease (PCKD) presented with jaundice, fever, and abdominal pain. A computered tomographic (CT) scan performed immediately after an endoscopic retrograde cholangiopancreatogram (ERCP) clearly demonstrated a hepatic cyst obstructing the biliary system. The cyst was then aspirated under ultrasound guidance with complete relief of obstruction.     

Hydatid hepatic cysts rupture into the biliary tract, the peritoneal cavity, the thoracic cavity and the hepatic subcapsular space: specific computed tomography findings

Background: This study attempts to demonstrate the role of computed tomography in the diagnosis of hepatic hydatid cyst rupture based on specific imaging findings and to propose combinations of the imaging findings diagnostic for specific types of rupture. Methods: Eleven patients were studied with computed tomography of the abdomen, with 4–8 mm slice thickness, after the oral administration of contrast material and intravenous contrast material in 6 cases. Results: Based on a combination of imaging findings the types of hepatic hydatid cyst rupture were: intrabiliary rupture in 7 patients, intraperitoneal rupture in 1 patient, intrathoracic rupture in 1 patient, hepatic subcapsular rupture in 2 patients. Structural deformity of the cyst was present in all cases, combined with: dilatation of the intrahepatic bile ducts (intrabiliary rupture); intraperitoneal fluid collections with diffuse haziness and stranding of the mesenteric fat (intraperitoneal rupture); an inhomogeneous lesion in the thorax with ipsilateral pleural effusion (intrathoracic rupture); a hydatid cyst located peripherally, with discontinuity of its adjacent to the hepatic capsule wall and subcapsular fluid collection (subcapsular rupture). The imaging findings were surgically and pathologically confirmed. Conclusions: Using combinations of specific imaging findings we correctly diagnosed the type of hepatic hydatid cyst rupture in all cases.     

A hydatid cyst of the thyroid gland

Echinococcosis, although eradicated in many countries, is still widespread in communities in which agriculture is dominant, and cystic hydatidosis is a significant public health problem in regions where echinococcosis is endemic. Hydatid cysts may be found in almost any part of the body, but most often in the liver and lungs. Other organs affected occasionally include the brain, muscle, kidney, bone, heart and pancreas. This report documents a rare case with a cystic nodule in the thyroid detected by ultrasonography. The patient was a 40-year-old woman with an euthyroid multinodular goitre. Ultrasonography revealed a cystic nodule, and the ultrasonic appearance of the cyst liquid showed multiple echoes, suggesting that the nodule could be a hydatid cyst. Bilateral subtotal thyroidectomy was performed. Postoperative examination of the nodule showed it to be a solitary primary thyroid hydatid cyst.
