- A patient was admitted to the Internal Medicine Department after suffering from fever for 4 days. A splenic abscess was found in an ultrasound examination and was confirmed by an abdominal computerized tomography and galium scan. Antibiotic treatment was successful, however barium enema was performed due to the lack of a predisposing factor for this unusual abscess. A polypoid mass was found in the splenic flexure of the colon. Colonoscopy and histologic examination confirmed the mass to be colonic adenocarcinoma. Either an endoscopic examination or barium enema are recommended to exclude colonic lesions in cases of splenic abscess without an obvious cause.
