A case of accessory splenic tuberculosis mimicking a distal pancreatic tumor / 대한내과학회지

ABSTRACT

Abdominal tuberculosis usually affects the gastrointestinal tract, peritoneum, lymph nodes, liver or spleen. Tuberculosis of the spleen is uncommon, except when associated with miliary dissemination. We report a case of a 33-year-old man with tuberculosis of the accessory spleen, which was originally suspected to be a distal pancreatic tumor. He was admitted with a history of left upper quadrant abdominal pain for 3 months. Computed tomography imaging of the abdomen revealed a 4.5 cm sized poorly defined hypodense mass in the distal pancreas and showed multiple focal hypodense lesions in the enlarged spleen. We performed distal pancreatectomy and splenectomy under the preoperative expectation of a distal pancreatic tumor. Microscopic examination of the specimens revealed accessory splenic tuberculosis associated with splenic tuberculosis. Following this, he was treated with appropriate antituberculosis drugs and was discharged without any complications.
