case_images: (A, B) 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) detected the presence of an FDG-avid tumor (arrow) in the ascending colon (A) and peritoneal nodules (arrowheads) (B). (C) A biopsied peritoneal nodule showed epithelioid cell granuloma with partial necrosis on hematoxylin-eosin staining. (D) Abdominal CT showed a thickened peritoneum with massive ascites at the onset of tuberculosis peritonitis.

case_images: Three months later, a solitary tumor at the ascending colon and several peritoneal nodules were identified by colonoscopy and 18F-fluorodeoxyglucose-positron emission tomography combined with computed tomography (Figure 1A and B). Laparoscopic surgical resection of the colon tumor and peritoneal nodules resulted in a histologic diagnosis of adenocarcinoma for the ascending colon tumor and epithelioid cell granulomas with partial necrosis for the peritoneal nodules (Figure 1C). A CT scan showed the emergence of an abnormally thickened peritoneum and massive ascites (Figure 1D).
