Orbital hydatid cyst

Hydatid cysts rarely appear in the orbital cavity without the involvement of the other organs. Most of them are situated in the superolateral and superomedial angles of the orbit. Inferiorly located cysts are very uncommon. The authors report a case of a primary hydatid cyst of the orbit with inferolateral localization. The cyst was removed surgically via a frontotemporoorbitozygomatic approach combination with puncture-aspiration-injection-reaspiration technique. This case was considered as a primary infection, because there was no previous history of hydatid disease and no findings of liver and lung cysts on radiological examination. Physicians should include orbital hydatid cyst in the differential diagnosis of unilateral proptosis. To avoid complications that might occur during surgery, the cyst can be easily removed using the combination technique detailed in this report.     

Dyspnée laryngée révélatrice d’une localisation cervicale d’hydatidose : à propos d’un casLaryngeal dyspnea with a hydatid etiology.

Hydatid cysts rarely present as a cervical tumor. We report a case of hydatid cyst of the neck in a child with multiple hydatid cysts in the liver, which was revealed by laryngeal dyspnea. Symptoms occurred in a six year-old country dweller, who presented with progressive laryngeal dyspnea. The chest radiographs showed extrinsic tracheal compression. A cervical ultrasonography showed a liquid filled mass evocative of hydatid cyst type 1. Explorative cervicotomy confirmed the diagnosis. The treatment was conservative after destruction of the parasite using a hypertonic saline solution. The immediate result was the disappearance of the laryngeal dyspnea.     

Intraventricular neurocysticercus cyst(s) in Indian children

Eleven cases of intraventricular neurocysticercosis were managed over a 10-year period. All patients presented with features of hydrocephalus. In 9 cases the cysts were blocking the cerebrospinal fluid (CSF) pathway resulting in hydrocephalus. The 4 cases of lateral ventricular cyst had communicating hydrocephalus, while 2 of these had asymmetrical ventriculomegaly. Two of 4 cases had more than one cyst. One of 4 children with lateral ventricular cyst had narrowing of the foramen of Monro causing asymmetrical hydrocephalus. Following cyst removal, CSF diversion was not required in 6 cases, while 5 required CSF diversion despite removal of their cysts in 4 of 5. One patient had a cyst at the aqueductal inlet and he was managed by shunt and albendazole therapy. Thus, we managed 6 of our cases with excision of the cysts obstructing the CSF pathway, and in 4 cases excision of cysts with ventriculoperitoneal shunt was adequate.     

Hydatid cyst presenting as a soft-tissue calf mass in a child.

Hydatid disease caused by Echinococcus granulosus often manifests as a slow growing cystic mass; it mainly affects the liver or lung and rarely other parts of the body such as the brain, heart, spleen, peritoneal cavity, or bone. Hydatid cysts of the musculoskeletal system are rare. Since the intramuscular hydatid cyst closely resembles a soft-tissue tumor on clinical examination, the preoperative radiological diagnosis is very important for the identification of the lesion prior to surgery. We describe a rare case of primary intramuscular hydatidosis in a child, together with its clinical presentation and radiological and histological findings. The treatment principles for hydatid cysts are also discussed.     

Retroperitoneal laparoscopic approach for renal hydatid cyst in children. A technical report

Renal hydatid disease is a rare pathological condition in children. Hydatid cyst of the kidney corresponds to 2–4% of all hydatid disease cases. Minimally invasive techniques have been used in the treatment of renal hydatid cysts but surgical experience is limited. We report a 10-year-old patient with a left renal hydatid cyst treated using a retroperitoneal laparoscopic technique.     

Pseudo food allergy

Hydatid disease is a common zoonosis caused by the larval cysts of Echinococcus granulosus (parasitic tapeworm). In children, lung hydatid cysts are more common than liver cysts, whereas in adults the reverse is true. Pulmonary hydatids can be accompanied by concurrent liver cysts. Leakage or rupture of a hydatid cyst can cause allergic reactions including anaphylaxis. Albendazole is effective therapy either alone or as an adjunct to surgery.     

Salmonella typhi-infected lung hydatid cyst

A 12-year-old girl presented with hemoptysis, fever and weight loss. She was initially diagnosed and treated for presumed tuberculosis and a lung abscess. Salmonella typhi was isolated from the abscess. Hydatid cyst was diagnosed at surgery. This is the first reported case of a pulmonary hydatid cyst infected with S. typhi.     

Hydatid cyst of the renal pelvis

Hydatid disease is fairly common and is prevalent worldwide. The principal organs involved are the liver and lungs. Kidney involvement also occurs but usually with involvement of other viscera. Isolated hydatid cyst of the kidney is extremely uncommon. In the kidney, the hydatid cyst usually occurs in the renal parenchyma. We present a rare occurrence of a hydatid cyst of the renal pelvis in a 4-year-old child and discuss measures to decrease surgical morbidity.     

A large cerebral hydatid cyst associated with liver cyst

Hydatid disease in childhood is a serious health problem in Turkey and other places where the parasite is endemic. An 8-year-old girl from a rural area was admitted with headache, recurrent abdominal pain, abdominal distension and hypo-aesthesia and paresis of the right arm. Computerised tomography (CT) scans demonstrated a large intracranial hydatid cyst. A hydatid cyst was detected in the liver also. Her mother had been treated previously for disseminated hydatid disease. The cerebral cyst was removed but only subtotal excision of the hepatic cyst was possible. She was treated with albendazole, has fully recovered and, after 12 months of follow-up, there is no sign of recurrence.     

Bobble-head doll syndrome

A new case of Bobble-head doll syndrome with aqueductal stenosis is presented in a 14 year-old boy. Ventriculocisternostomy performed 8 years after the onset of the abnormal movement resulted in moderate reduction of the head bobbling. Twenty-two cases were found in a review of the literature. In all cases there was a chronic slowly progressive hydrocephalus with usually a cyst of the third ventricle; aqueductal stenosis was less frequent. When recorded, psychomotor development was impaired. Treatment is neurosurgical. Pathogenesis remains unknown.     

Primary hydatid cyst of the thigh: a case report of an unusual localization

The sartorius muscle is a rare location of primary hydatid cyst. In this report, the clinical, pathologic, and radiologic features are discussed, with special emphasis on the pathologic and radiographic features. We report a case of hydatid cyst of the proximal thigh in an eight-year-old girl. Magnetic resonance (MR) images revealed muscular hydatid cyst in the sartorius muscle, with a striking appearance of daughter cysts. We did not find any visceral organ involvement. Wide excision was performed without destroying the cyst wall. Primary muscular hydatidosis should be kept in mind in the differential diagnosis of a cystic mass of a skeletal muscle.     

Children presenting with hydatid cysts in common bile duct and choledochal cyst

Hydatid cysts developing primarily in the common bile duct are extremely rare. Occasionally, hydatid cysts rupture into the extrahepatic biliary ducts and cause obstruction [1–7]. Two children with intact hydatid cysts in the common bile duct and choledochal cysts were seen during a 2-year period in the Paediatric Surgery Division of the Children's Hospital, Banaras Hindu University, Varanasi. The details of their presentation and operative management are reported.     

Aqueductal stenosis presenting as isolated tremor: case report and review of the literature

Essential tremor is rare in children, particularly in the absence of a significant family history. We report the case of a child with compensated hydrocephalus secondary to aqueductal stenosis whose sole presenting symptom was tremor. An otherwise healthy 6-year-old male developed a fine hand tremor, which over the course of 4 years both increased in intensity and spread to involve the lower limbs and head. After an MRI had confirmed hydrocephalus due to aqueductal stenosis, the patient underwent an endoscopic third ventriculostomy. His tremor improved markedly, but did not completely resolve. Occult hydrocephalus should be considered in the differential diagnosis of new-onset tremor. Progression of the tremor should halt with treatment of the hydrocephalus, and clinical improvement may be seen.     

Surgical treatment of pulmonary hydatid cysts in children: report of 66 cases.

AIM OF THE STUDY: Hydatid disease is a parasitic infestation which is endemic in many sheep and cattle raising areas and is still an important health problem in the world. The aim of our study was to present our surgical experience and strategy in the management of pulmonary hydatid disease. METHODS: Sixty-six patients with 83 pulmonary hydatid cysts underwent surgical treatment in our institution between January 1990 and March 2003. We used double-lumen endotracheal tubes in children older than 12 years who were operated on for hydatic cyst in the last 8 years. RESULTS: There were 38 boys and 28 girls with a mean age of 9.6 +/- 7 years (range 5-15 years). Of the 83 cysts, 61 were intact and 22 were ruptured cysts. Isolated pulmonary hydatid cyst was seen in 61 patients (92.4 %), while 5 patients (7.6 %) had combined pulmonary and hepatic cysts. Lateral thoracotomy was performed in 54 patients (82 %), thoracophrenotomy in 5, bilateral thoracotomy in 4, and median sternotomy in 3 patients. Cystotomy and capitonnage was performed in 58 cysts, cystotomy alone in 21, and resection techniques were used in 4. There were 8 postoperative complications in 7 patients. The most common complication was atelectasis. CONCLUSIONS: Surgery is the treatment of choice for most patients with pulmonary hydatid cysts. The usage of double-lumen tubes may decrease intra- and postoperative complications. Thoracophrenotomy can be chosen as the surgical procedure in the management of hepatic and pulmonary hydatid cysts.     

Hydatid cysts in children. Diagnostic and therapeutic aspects. Apropos of 1195 cases

Hydatid cysts represent a true social problem in Tunisia where 2.1% of rural inhabitants are affected. Hydatid disease is responsible for 10% of the country's surgical activity and costs approximately 800 $ per patient. From April 1967 through January 1987, 1,195 cases of hydatid cyst in children aged 2 to 15 years were treated at the Children's Hospital in Tunis. The involved organ was the lung in 643 cases, the liver in 486 cases, the spleen in 27 cases, and the kidney in 18 cases. With the exception of seven patients with malignant forms, surgery was always performed, with a 1.4% mortality rate and a 2% morbidity rate. We analyze the diagnostic and therapeutic particularities of the various locations of hydatid cyst. Diagnosis rests mainly on ultrasound findings and treatment on conservative procedures as hydatid disease in children carries a good prognosis.     

Severe mitral regurgitation and hepatopulmonary hydatid cysts: what should be treated first?

Hydatid cyst can simultaneously affect the liver and lung. Some patients might have additional comorbidities that can make management more challenging. Here, we present a 10-year-old boy with hepatopulmonary hydatid cysts and severe mitral regurgitation, who was successfully managed with a staged surgical approach treating the lung first, followed by the liver and finally, the heart.     

A sacral hydatid cyst mimicking an anterior sacral meningocele

Hydatid disease is a zoonosis caused by Echinococcus granulosus. It is a progressive disease with serious morbidity risks. Sacral hydatid disease is very uncommon, accounting for < 11% of spinal hydatidosis cases. The diagnosis of a sacral hydatid cyst is sometimes difficult because hydatidosis can simulate other cystic pathologies. The authors report on 9-year-old boy admitted to their service with a paraparesis that allowed walking without aid. The boy presented with a 2-year history of an evolving incomplete cauda equina syndrome as well as a soft cystic mass in the abdomen extending from the pelvis. Radiological examination revealed an anterior meningocele. A posterior approach with laminectomy from L-5 to S-3 was performed. Three lesions with classic features of a hydatid cyst were observed and removed. The diagnosis of hydatid cyst was confirmed histopathologically. Antihelmintic treatment with albendazole (15 mg/kg/day) was included in the postoperative treatment. The patient's condition improved after surgery, and he recovered normal mobility. The unusual site and presentation of hydatid disease in this patient clearly supports the consideration of spinal hydatid disease in the differential diagnosis for any mass in the body, especially in endemic areas.     

Bronchogenic cyst of the lung mimicking a pulmonary hydatid cyst in a child

Lung bronchogenic cyst may be infected and present with symptomatology and chest radiological findings compatible with an infected lung cyst, including pulmonary hydatid cyst. We describe a case of a 5-year-old girl with a symptomatic solitary mass in the right lower lobe that was initially treated as a hydatid cyst. Eventually, a lobectomy was performed, and a final diagnosis done on pathology showed an infected congenital bronchogenic cyst.     

Classic and unusual appearances of hydatid disease in children

BACKGROUND: In endemic regions, hydatid disease is commoner in children than in adults. The hydatid cysts may have classic appearances, but unusual sites and appearances may cause diagnostic difficulties. OBJECTIVE: To assess the classic and unusual appearances of hydatid disease in children. MATERIALS AND METHODS: A 3-year retrospective review of available imaging of proven hydatid disease at a tertiary paediatric institution. RESULTS. Review of imaging of 21 children (9 boys, 12 girls), with a mean age of 8 years and 1 month, demonstrated cysts in the liver ( n=9), lung ( n=8), brain ( n=7), spleen ( n=2), heart ( n=1), orbit ( n=1) and soft tissues ( n=1). Multi-organ involvement occurred in eight cases with two cases that did not involve the liver. Complicated cysts were found in 13 cases and usually involved the liver ( n=8) and lung ( n=5). An unusual case of spontaneous cerebrospinal fluid (CSF) spread was also documented. CONCLUSIONS: Hydatid disease in children classically involves the liver, lung and brain but can involve almost any organ and numerous organs simultaneously. Whether hydatid disease is discovered incidentally or by intentional imaging, extended imaging is recommended to identify multifocal disease which may also display complicated cysts that may assist in the diagnostic process. All patients with one known site should undergo a minimum of an abdominal US and CT scan of the chest and brain. CT may be used instead of US of the abdomen, and MRI may be used to replace CT of the brain. Over 50% of cases in our study showed complicated cysts. Unique findings of this study include multi-organ involvement without liver cysts. Multiplicity and complications of cysts can assist diagnosis. Intraventricular and intrathecal CSF spread of a spontaneously ruptured intracerebral cyst has not, to our knowledge, been previously reported.     

Pericardial hydatid cyst with a fatal course

Cases with cardiac hydatid cyst disease are uncommon, being approximately 0.2–2% of all cases. Most cardiac hydatid cysts are located in the interventricular septum or left ventricular wall. Pericardial location is very rare. We report on a 12 year old girl with pericardial hydatid cyst disease who was otherwise asymptomatic, having no cardiac symptomatology. Unfortunately the course of her disease was fatal. This is the first report of uncommon localized hydatid disease with a fatal outcome.
