A 77-year-old man with a low grade fever persisting for 30 days consulted a local physician. A computed tomographic scan of the abdomen showed a mixed density mass on the left adrenal gland. He was referred to our hospital for further examination. Hormonal assay demonstrated a slightly high level of noradrenalin in the serum (18 pg/ml) and vanillyl mandelic acid in the urine (6.2 ng/ml). Magnetic resonance imaging revealed a heterogeneous mass lesion 3 cm in diameter with a high signal intensity on both T1 and T2 weighted images. Angiography showed a hypovascular mass in the supra-renal region suggesting an adrenal tumor or malignancy. Left adrenalectomy combined with en bloc nephrectomy was performed because of severe adhesion. Histologic evaluation showed hematoma without malignant cells due to idiopathic adrenal hemorrhage.
