Esophageal intramural hematoma: an unusual complication of endoscopic biopsy

An atypical case of fatal 'esophageal apoplexy': post-mortem findings and differential diagnosis

Forensic pathologists need to have comprehensive knowledge of a large variety of causes of sudden natural death. We describe a case of sudden and unexpected death in woman in her sixties due to rupture of a large paraesophageal hematoma. The post-mortem examination and differential diagnosis are discussed. The combined findings of whole-body post-mortem CT imaging (PMCT), targeted PMCT angiography, autopsy, and histology are most in keeping with 'esophageal apoplexy'; a rare cause of hemorrhage in the esophageal wall. A review of the literature indicates that most cases of esophageal apoplexy are self-limiting and that fatal complications are exceedingly rare. Our case demonstrates that esophageal apoplexy can present as sudden unexpected death.

Unusual clotted haemothorax caused by spontaneous intramural haematoma of the oesophagus: a case report

Spontaneous intramural haematoma of the oesophagus (SIHO) is a relatively rare event with benign courses. Most of the patients with SIHO may experience spontaneous healing without complications. We report a case of SIHO with clotted haemothorax. Uniportal video-assisted thoracic surgery (VATS) was successfully applied as a diagnostic and therapeutic method. Although conservative treatment is adequate for the majority of patients with SIHO, uniportal VATS may be a suitable option if there was clotted haemothorax.

Intramural hematoma of the esophagus after endoscopic pinch biopsy

Intramural hematoma of the esophagus (IHE) is an uncommon form of esophageal injury, which may be an intermediate of mucosal tear (Mallory-Weiss syndrome) or transmural rupture (Boerhaave's syndrome). To date, the pathogenesis of IHE has not been well documented. IHE may occur within the submucosal layer of the esophagus following dissection of the mucosa. The most commonly presented symptoms are sudden retrosternal pain, dysphagia and hematemesis. The disorder can occur spontaneously or secondarily to trauma. In this report, we present a case of IHE which occurred after endoscopic biopsy and was recovered following conservative management in a patient who was taking long-term aspirin medication.

Nonvascular, nontraumatic mediastinal emergencies in adults: a comprehensive review of imaging findings

Given their high frequency, mediastinal emergencies are often perceived as being a result of external trauma or vascular conditions. However, there is a group of nonvascular, nontraumatic mediastinal emergencies that are less common in clinical practice, are less recognized, and that represent an important source of morbidity and mortality in patients. Nonvascular, nontraumatic mediastinal emergencies have several causes and result from different pathophysiologic mechanisms including infection, internal trauma, malignancy, and postoperative complications, and some may be idiopathic. Some conditions that lead to nonvascular, nontraumatic mediastinal emergencies include acute mediastinitis; esophageal emergencies such as intramural hematoma of the esophagus, Boerhaave syndrome, and acquired esophagorespiratory fistulas; spontaneous mediastinal hematoma; tension pneumomediastinum; and tension pneumopericardium. Although clinical findings of nonvascular, nontraumatic mediastinal emergencies may be nonspecific, imaging findings are often definitive. Awareness of various nonvascular, nontraumatic mediastinal emergencies and their clinical manifestations and imaging findings is crucial for making an accurate and timely diagnosis to facilitate appropriate patient management.

Bowel obstruction caused by an intramural duodenal hematoma: a case report of endoscopic incision and drainage

Complications associated with an intramural hematoma of the bowel, is a relatively unusual condition. Most intramural hematomas resolve spontaneously with conservative treatment and the patient prognosis is good. However, if the symptoms are not resolved or the condition persists, surgical intervention may be necessary. Here we describe internal incision and drainage by endoscopy for the treatment of an intramural hematoma of the duodenum. A 63-yr-old woman was admitted to the hospital with hematemesis. The esophagogastroduodenoscopy (EGD) showed active ulcer bleeding at the distal portion of duodenal bulb. A total of 10 mL of 0.2% epinephrine and 2 mL of fibrin glue were injected locally. The patient developed diffuse abdominal pain and projectile vomiting three days after the endoscopic treatment. An abdominal computed tomography revealed a very large hematoma at the lateral duodenal wall, approximately 10 x 5 cm in diameter. Follow-up EGD was performed showing complete luminal obstruction at the second portion of the duodenum caused by an intramural hematoma. The patient's condition was not improved with conservative treatment. Therefore, 21 days after admission, endoscopic treatment of the hematoma was attempted. Puncture and incision were performed with an electrical needle knife. Two days after the procedure, the patient was tolerating a soft diet without complaints of abdominal pain or vomiting. The hematoma resolved completely on the follow-up studies.

Intramural hematoma of the esophagus: a pictorial essay

Intramural hematoma of the esophagus (IHE) is a rare but well-documented condition that is part of the spectrum of esophageal injuries which includes the more common Mallory-Weiss tear and Boerhaave's syndrome. Acute retrosternal or epigastric pain is a common clinical feature, which can be accompanied by dysphagia, odynophagia, or hematemesis. An early differentiation from Mallory-Weiss tear, Boerhaave syndrome, ruptured aortic aneurysm, aortic dissection, acute myocardial infarction, or pulmonary pathology can be difficult. Computed tomography (CT) is the imaging modality of choice and characteristically reveals a concentric or eccentric thickening of the esophageal wall with well-defined borders and variable degree of obliteration of the lumen. Measurement of the attenuation values within the lesion will reveal blood density which varies according to the age of the hematoma. CT should be considered the preferred diagnostic technique, thereby facilitating proper clinical management. Early diagnosis is crucial as most patients may be treated conservatively with good outcome.
