Simultaneous renal vein thrombosis and bilateral adrenal hemorrhage: MR demonstration.

A case of simultaneous renal vein thrombosis and bilateral adrenal hemorrhage is presented, demonstrating the ability of magnetic resonance (MR) imaging to identify these abnormalities without the use of intravenous contrast agents or radiopharmaceuticals. Adrenal hemorrhage appeared as markedly enlarged adrenal glands with homogeneous high signal intensity on both T1 and T2 weighted spin echo MR images. The kidney involved with renal vein thrombosis was enlarged and demonstrated increased signal from the renal parenchyma on T2 weighted images.
