An Uncommon Presentation of Extrapulmonary Tuberculosis Masquerading as Ovarian Malignancy in a Young Female.

Tuberculosis (TB) is chronic granulomatous infection caused by bacteria, Mycobacterium tuberculosis, which primarily involves the lungs. Abdominal TB is an extrapulmonary disease which can mimic malignancy, especially in women with ascites, weight loss, and high cancer antigen-125 levels. Here, we report a case of young female, where clinical and radiological features were suggestive of ovarian malignancy. However, the pattern of uptake on flourine-18 fluorodeoxyglucose positron emission tomography/computed tomography raised the suspicion of a chronic infectious disease. The final diagnosis was confirmed as TB by cytology and started on antituberculous treatment. She had a good response and remission of lesions after 4 months of treatment.
