Coexisting renal vein thrombosis and bilateral adrenal hemorrhage: renoscintigraphic demonstration.

A rare case of simultaneous renal vein thrombosis and bilateral adrenal hemorrhage is presented, showing the utility of Tc-99m DTPA and DMSA renal scans to identify the condition and to assess renal function. The characteristic appearances of suprarenal tracer-free areas encircled by peripheral radioactive rims over the inferiorly displaced kidneys on a Tc-99m DTPA renal scan, and that of the flattened upper poles of the kidneys on a Tc-99m DMSA scan, were pathognomonic and strongly indicative of bilateral adrenal hemorrhage. These two scans also showed markedly diminished tracer uptake in the poorly functioning right thrombosed kidney. Follow-up imaging using these two renal scans well demonstrated the functional and morphologic alterations and recovery of the kidneys.
