Upside-down spleen as cause of suprarenal mass.
An upside-down configuration of the spleen can be mistaken for a left suprarenal mass. A radioisotopic liver-spleen scan will demonstrate a characteristic appearance of the spleen with its hilus superiorly and its convex border medially and adjacent to the kidney. When a left suprarenal mass is identified, we advocate the liver-spleen scan as the first step in the diagnostic workup. If the typical configuration is found, no further studies are necessary.
