Tuberculous peritonitis mimicking carcinomatosis peritonei: CT findings and histopathologic correlation.

The distinction between tuberculous peritonitis and peritoneal carcinomatosis is extremely difficult in patients with omental cake appearance on computed tomography and elevated CA-125 level. A 21-year-old female presented with abdominal distention, diarrhea, nausea, fever, weight loss, and night sweats. Serum CA-125 level was 563 U/L (normal range: <35 U/L) and other tumor markers were within normal range.
