Peritoneal tuberculosis may present from mild pain abdomen to more complex presentations as that of intestinal obstruction. They remain a diagnostic and treatment challenge to the surgeon. A thorough history and physical examination along with imaging modalities such as ultrasound, CT- scan abdomen and histopathological investigations like FNAC and biopsy aids the surgeon in making the diagnosis in majority of cases. There have been reported similar cases but mostly were diagnosed after laparotomy. Thus in a
case presenting with ascitis, pain abdomen, bulky adnexa, raised CA-125 and
negative microbiology and histology; the differential diagnosis of peritoneal tuberculosis should always be borne in mind.
