Intra-abdominal tuberculosis (TB) is rare in Australia, but it can be found in those who emigrate from endemic areas. We report a rare case of a 28-year-old lady from the Philippines who presented with abdominal pain, ascites and an elevated cancer antigen (CA) 125 with an initial concern of ovarian malignancy. She underwent a diagnostic laparoscopy which revealed typical features of intra-abdominal TB and histological features of granulomatous inflammation. The symptoms and signs of intra-abdominal TB are non-specific and can mimic many other conditions. The gold-standard mode of diagnosis in intra-abdominal TB is laparoscopy with tissue biopsy. Ovarian malignancy is relatively rare in pre-menopausal women; hence an elevated CA 125 warrants a broader differential diagnosis. It is important to have intra-abdominal TB as a differential even in the non-endemic settings to avoid delay in diagnosis and appropriate management.
