SPLENIC VEIN-THROMBOSIS SECONDARY TO FOCAL PANCREATITIS DIAGNOSED BY ENDOSCOPIC ULTRASONOGRAPHY

We report splenic vein thrombosis diagnosed by endoscopic ultrasonogra phy (EUS) after thr failure of extracorporeal ultrasound and contrast enhanced computed tomography to establish the diagnosis in a patient w ith gastrointestinal bleeding and anemia. Subsequent preoperative magn etic resonance imaging revealed findings of retroperitoneal fibrosis a nd confirmed the EUS findings. Splenic vein thrombosis is a well-known cause of gastrointestinal bleeding and splenomegaly: pancreatitis and pancreatic tumors are its most common underlying causes. Abdominal ul trasound and computed tomography are frequently used to diagnose splen ic vein thrombosis. We discuss the use of EUS for diagnosis of vascula r anomalies in the gastrointestinal tract and tile association of sple nic vein thrombosis, retroperitoneal fibrosis, and pancreatitis.
