Spontaneous hematoma of posterior mediastinum with an uncommon cause: a case report and review of the literature

Abstract

Spontaneous mediastinal hematoma is exceedingly rare. We described such a case of a 61-year-old male with a posterior mediastinal hematoma from ruptured small aneurysm, which was ascertained via contrast-enhanced computed tomography examination. Subsequent super-selective angiography of left gastric artery revealed a ruptured aneurysm with contrast medium leakage, feeding vessels respectively from caudal and cranial artery. The left gastric artery branch caudally feeding aneurysm was successfully occluded, while cranially feeding artery from the branch of left bronchial artery failed to embolize due to complex anatomic factor. Our management still yields to a satisfactory outcome.
