Abstract
Abstract Back ground: Adrenal hematoma is a rare yet potentially life-threatening event that occurs both in traumatic conditions and in a variety of nontraumatic conditions. In the present study, we report the two cases with idiopathic unilateral adrenal hematoma, presenting as a huge adrenal mass. Case presentation: Case 1 involved a 72-year-old man who was complaining of upper abdominal pain. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a giant mixed density tumor in the right retroperitoneal space. Based on the radiological findings, the preoperative differential diagnoses included adrenal cancer, pheochromocytoma, an adrenal hematoma, and a primary retroperitoneal tumor. To remove the tumor we carried out an adrenalectomy on the right adrenal gland, resecting a specimen measuring 15 × 13.5 cm. The histopathological findings of the specimen revealed a hematoma with normal adrenal tissue. Case 2 involved a 53-year-old woman who complained of an uncomfortable feeling in her left upper abdomen. An Abdominal CT and MRI showed that a retroperitoneal tumor had formed a multicystic lesion. Due to the tumor’s size, the left renal vein had become compressed and therefore, was resected by left adrenalectomy. The resected specimen was 10.5 × 10 cm in size and revealed an adrenal hematoma. In the absence of any obvious etiology, the diagnoses in both cases were idiopathic adrenal hematoma. Conclusion: An accurate diagnosis of idiopathic adrenal hematoma is quite difficult to make prior to surgery. Some imaging modalities are useful in generating a differential diagnosis
