[Unspecific abdominal complaints: diagnosis with szintigraphy].

This case report describes a 65-year old man with symptomatic abdominal and pelvic splenosis. 50 Years ago he has had splenectomy after a road traffic accident. Ultrasound and CT revealed a bulky mass in the iliac fossa and multifocal intraabdominal nodules suggesting peritoneal carcinomatosis. Scintigraphy with Tc-99m-labelled heat damaged red blood cells led to definitive diagnosis. RBC-scintigraphy is a specific, easy performable diagnostic tool. It is cost-effective and can avoid other diagnostic procedures or explorative surgery.
