Spontaneous intramural esophageal hematoma: case report and review.

Intramural esophageal hematoma is a rare form of esophageal injury. The presenting symptoms are nonspecific. Esophagogastroscopy and computed tomography scan are usually needed to establish the diagnosis of intramural esophageal hematoma. Presented here is a patient with spontaneous intramural esophageal hematoma who was successfully treated with conservative measures.     

The usefulness of contrast-enhanced echocardiography in the diagnosis and management of intramural hematoma and aortic dissection: A case report

Contrast-enhanced transthoracic echocardiography (cTTE) plays an important role in the diagnosis of intramural hematoma (IMH) and aortic dissection (AD), and is also necessary for the adequate management from the assessment of findings. We hereby present an interesting case in which cTTE provides additional value over contrast-enhanced computed tomography (CT) in the diagnosis and the morphological characterization of IMH and AD. A 58-year-old man presented to the emergency department with intermittent chest pain. After emergency consultation, an enhanced CT scan showed an acute aortic intramural hematoma involving aortic arch and descending aorta. Nevertheless, the entry tear and false lumen flow direction were identified by cTTE, which suggested an acute type B AD.     

Intramural duodenal hematoma after endoscopic therapy for a bleeding duodenal ulcer in a patient with liver cirrhosis

We report a case of intestinal obstruction due to intramural hematoma of the duodenum following therapeutic endoscopy for a bleeding duodenal ulcer in a patient with liver cirrhosis. A 44-year-old man was admitted to our hospital with severe epigastralgia, nausea and tarry stool. Two years previously he had undergone endoscopic sclerotherapy for esophageal varices caused by alcoholic liver cirrhosis. Endoscopy revealed an open ulcer with a bleeding vessel in the duodenal bulb, and sclerotherapy was performed by clipping the vessel and injecting 20 ml of 0.2% epinephrine. His platelet count was 3.5x10(4)/mul. Twelve hours later, he again developed epigastralgia and hypotension. Emergency computed tomography and ultrasonography revealed an intramural hematoma, 15x18 cm in diameter, at the dorsal and lateral duodenum. Endoscopy and upper gastrointestinal series revealed severe stenosis of the duodenal lumen caused by intramural hematoma. He received parenteral feeding for 22 days and within 8 weeks the hematoma was gradually absorbed using conservative management. Intramural duodenal hematoma may be diagnosed as a complication of the endoscopic procedure in a patient with a bleeding tendency, such as liver cirrhosis.     

Nontraumatic intramural hematoma of the duodenum

We present a case of nontraumatic intramural hematoma of the duodenum. A 77-year-old woman complained of nausea, vomiting, and abdominal pain during hospitalization. There was no traumatic episode. Laboratory data showed anemia (hemoglobin, 7.7 g/dl). The diagnosis was confirmed by computed tomography (CT), which showed a mixed hyperdense and hypodense mass obstructing the third portion of the duodenum. The cause was considered to be bleeding tendency caused by an antiplatelet drug. The patient was treated conservatively and the size of the hematoma was followed on CT. She was able to resume oral feeding 2 weeks after admission.     

Diagnosis by magnetic resonance imaging of a case of intramural left atrial hematoma

We report a case of spontaneous intramural left atrial hematoma with chest pain and pulmonary edema as the primary clinical manifestations. Echocardiographic techniques revealed obstruction of the left atrial cavity by cyst-like masses attached to the posterior and anterior atrial wall. A large intramural hematoma due to extensive atrial wall dissection was observed by magnetic resonance imaging. Surgery confirmed the diagnosis of intramural left atrial hematoma with no complications. We review the clinical and diagnostic profile of the three cases of spontaneous intramural left atrial hematoma reported in the world medical literature.     

Rapidly growing cardiac mass: a rare case of left atrial intramural hematoma complicating coronary artery stenting

Formation of an intramural left atrial hematoma (ILAH) is a rare complication of coronary artery stenting. Rapid diagnosis with noninvasive multimodality imaging can potentially be lifesaving. We report a case of ILAH that resulted in left ventricular inflow obstruction and pericardial tamponade in a 55‐year‐old male who presented with hemodynamic instability and worsening dyspnea three weeks after seemingly uncomplicated left circumflex artery stenting. We demonstrate features on transthoracic echocardiography with contrast and cardiac computed tomography that were used for diagnosis and management.     

So-called spontaneous intramural dissection of the esophagus

We report two cases of spontaneous esophageal intramural dissection in two women aged 65 and 79 years. Initial symptoms were a constrictive retrosternal thoracic pain during a meal. Minor hematemesis accompanied by dysphagia or odynophagia appeared during the following hours. After excluding a cardiovascular emergency, diagnosis was confirmed by upper GI endoscopy that found a large mucosal longitudinal dissection; the lesion extended from mid-esophagus until short above the gastro-esophageal junction. Intramural parietal dissection characteristically appeared on barium swallow as a "double-barrelled" esophagus related to a thin radiolucent mucosal membrane separating the false and true lumens. Medical treatment with total parenteral nutrition, intravenous gastric antisecretory drugs, antibiotics in 1 patient was continued until symptoms disappeared; oral feeding was then started without incident. Follow-up endoscopic examinations confirmed complete healing. Regardless of etiology which remains speculative, spontaneous intramural dissection of the esophagus probably results from an intramural hematoma in most cases.     

Recurrent massive bleeding due to dissecting intramural hematoma of the esophagus： Treatment with therapeutic angiography

Spontaneous or traumatic intramural bleeding of the esophagus, which is often associated with overlying mucosal dissection, constitutes a rare spectrum of esophageal injury called dissecting intramural hematoma of the esophagus (DIHE). Chest pain, swallowing difficulty, and minor hematemesis are common, which resolve spontaneously in most cases. This case report describes a patient with spontaneous DIHE with recurrent massive bleeding which required critical management and highlights a potential role for therapeutic angiography as an alternative to surgery.     

Achalasia combined with esophageal intramural hematoma: case report and literature review

A 62-year-old male patient was admitted to our hospital due to severe chest pain,odynophagia,and hematemesis.Chest computed tomography showed an esophageal submucosal tumor.Esophagogastroduodenoscopy(EGD) revealed a longitudinal purplish bulging tumor of the esophagus.Endoscopic ultrasound(EUS) showed a mixed echoic tumor with partial liquefaction from the submucosal layer.The patient was diagnosed with esophageal intramural hematoma as well as achalasia by upper gastrointestinal endoscopy,esophagography an...     

Computed tomography of aortic intramural hematoma and thrombosed dissection

A retrospective study was undertaken to evaluate the appearance of the aortic wall on computed tomography for the purpose of developing criteria for differentiating acute aortic intramural hematoma from thrombosed false lumen seen in aortic dissection. Computed tomography angiography findings of the thoracoabdominal aorta in 23 patients with suspected intramural hematoma and 25 with thrombosed false lumen were reviewed. The more common features of an intramural hematoma were hyperattenuation of the aortic wall, wall thickness less than a quarter of the aortic diameter, intrinsic wall calcification, a lesion extending around the entire aortic circumference, and ulcer-like projections that may be precursors of intramural hematoma. Wall thickness less than a quarter of the aortic diameter, lesion extending around the entire aortic circumference, and ulcer-like projections were the most useful indicators for distinguishing intramural hematoma from the thrombosed false lumen in aortic dissection.     

CT灌注成像原始像点征预测急性自发性脑出血血肿扩大的初步研究

Dissecting intramural hematoma in esophageal carcinoma.

A 50-year-old man with esophageal carcinoma developed severe, refractory, retrosternal chest pain. The diagnosis was made four days later when contrast studies showed an intramural dissecting hematoma of the esophagus. The patient responded to conservative management.     

A rare case of penetrating atherosclerotic ulcer of the aorta

We are reporting a case of 66 year-old man who presented to a regional hospital with sudden onset of inter-scapular pain, radiating to anterior chest. Initial assessment was unremarkable except for high blood pressure and computed tomography (CT) of chest showing an intramural haematoma in the thoracic descending aorta. He was transferred to our institution for the medical management of his blood pressure and intramural haematoma of the aorta. A transoesophageal echocardiography confirmed the diagnosis but in addition demonstrated a penetrating atherosclerotic ulcer (PAU). Subsequently CT aortogram revealed a slow leak from the PAU. Endovascular repair with stent-grafting was urgently performed. He improved clinically and remained well on discharge. This case demonstrated that PAU, although rare and often under-recognised, is potentially life-threatening and should be considered in the evaluation of chest pain. Multi-modality imaging techniques can aid the diagnosis and guide appropriate and timely management.     

Intramural Duodenal Hematoma: An Unusual Complication of Endoscopic Small Bowel Biopsy

We report a case of intestinal obstruction secondary to intramural duodenal hematoma after endoscopic small bowel biopsy. Review of the literature indicates that intramural duodenal hematoma occurs mainly in infants and children after trauma to the abdomen. The diagnosis can be made by upper gastrointestinal series and confirmed by computerized axial tomography of the abdomen. Conservative management in the form of nasogastric suction and total parenteral nutrition resulted in amelioration of obstructive symptoms within 10 days. Physicians should be alerted to the possibility of developing intramural duodenal hematoma after small bowel biopsy. This is the first report of such an unusual complication after endoscopic small bowel biopsy in children.     

Pulmonary embolism and deep vein thrombosis complicating acute aortic dissection during medical treatment

Acute aortic dissection of Stanford type A with intramural hematoma was diagnosed based on computed tomography (CT) findings in a 60-year-old man. During medical treatment, pulmonary embolism and deep vein thrombosis developed. CT revealed thrombosis in the right pulmonary artery, and 99mTc pulmonary perfusion scintigraphy showed defects in the right lung field. CT showed thrombus in the common iliac vein. An inferior vena caval filter was placed because anticoagulation therapy was contraindicated. A CT scan before discharge showed no thrombus in the pulmonary artery or common iliac vein, but a newly captured thrombus was found inside the filter.     

Circumferential intramural esophageal dissection successfully treated by endoscopic procedure and metal stent insertion

Spontaneous intramural esophageal dissection is a rare disorder characterized by a lengthy laceration between the mucosal and submucosal layers of the esophageal wall, without perforation. The majority of previously reported cases of spontaneous intramural esophageal dissection were partial, and the circumferential type of intramural esophageal dissection has not been reported previously. Most spontaneous intramural esophageal dissection responds to conservative management, and usually it dose not lapse into a long protracted course of dealing with sequelae. We report an unusual case of circumferential intramural esophageal dissection, in which initial conservative management failed to alleviate the patient's dysphagia, necessitating the use of several endoscopic treatments, including incision of the septum between the false and true lumens, transection of the true esophageal wall, balloon dilatation, and metal stent insertion.     

Intramural hematoma of the esophagus caused by minor head injury 6 hours previously

The diagnosis of extensive intramural hematoma of the esophagus due to a bicycle trauma was considerably delayed because symptoms did not develop until 6 h after the accident. This report underscores the importance of a barium meal and computed tomographic (CT) scan in cases of unexplained chest pain, even after minor trauma.     

Spontaneous Intramural Hematoma of the Esophagus

Spontaneous intramural hematoma of the esophagus (SIHE) is a rare condition usually affecting middle-aged or elderly women. It presents as acute substernal or epigastric pain, typically accompanied by dysphagia or hematemesis. SIHE is not usually associated with vomiting, and is therefore clearly distinguished from emetogenic esophageal disorders, such as the Mallory-Weiss lesion and the Boerhaave syndrome. The diagnosis has traditionally been made by barium esophagram. Therapy is conservative; a favorable prognosis is the rule. The pathogenesis is in dispute. We present a case of SIHE without a discernible mucosal breach, suggesting a primary intramural bleed as the initiating event. We document the utility of computed tomographic scan and magnetic resonance imaging in the diagnosis of SIHE.     

Laparoscopic drainage of an intramural duodenal hematoma

A 21-year-old man was admitted with vomiting and abdominal pain 3 days after sustaining blunt abdominal trauma by being tackled in a game of American football. A diagnosis of intramural hematoma of the duodenum was made using computed tomography and upper gastrointestinal tract contrast radiography. The hematoma caused obstructive jaundice by compressing the common bile duct. The contents of the hematoma were laparoscopically drained. A small perforation was then found in the duodenal wall. The patient underwent laparotomy and repair of the injury. Laparoscopic surgery can be used as definitive therapy in this type of abdominal trauma.

Esophageal tuberculosis presenting as intramural esophagogastric hematoma in a hemophiliac patient.

A spontaneous intramural esophagogastric hematoma developed in a patient with hemophilia A. The hematoma did not resolve after antihemophiliac factor replacement but ruptured into the stomach causing massive gastrointestinal bleeding. The associated enlarged right tracheobronchial gland and the histopathological finding of fibrocaseating granuloma at the esophagogastric junction indicated that the primary disorder was esophageal tuberculosis. The whole process responded rapidly to antituberculous treatment.
