Idiopathic nontraumatic adrenal hematoma: a case report

This is a report of a rare case of an adrenal hematoma presenting as an incidentally detected abdominal mass in an otherwise asymptomatic patient, not associated with a neoplastic growth, a history of trauma or a coagulation disorder. The preoperative computed tomography findings were of a heterogeneously enhancing lobulated mass, thus prompting adrenalectomy for suspicion of malignancy. The surgical specimen, appearing intraoperatively to be a tumor with an attached adrenal gland, was then found upon histopathologic examination to consist of a hematoma of the periadrenal tissue and an unremarkable adrenal gland.
