Imaging as an alternate diagnostic modality in a presumptive case of abdominopelvic TB in a COVID-19 patient.

A 30-year-old, multiparous widow, with postpolio residual paralysis, presented with complaints of dull aching abdominal pain for 15 days. Ultrasound showed a mixed echogenic right adnexal mass with free fluid in the pelvis and abdomen. CT abdomen and pelvis revealed partially defined peripherally enhancing collection in lower abdomen and right adnexa suggestive of tubo-ovarian abscess. There was mild ileal wall thickening and few enlarged mesenteric lymph nodes. Ascitic fluid did not show acid fast bacilli and cultures were sterile. Extensive diagnostic laboratory work was done which was inconclusive. Diagnostic laparoscopy could not be performed due to non-availability of elective operation theatre in the COVID-19 pandemic. Presumptive extrapulmonary tuberculosis was clinically and radiologically diagnosed. She was started on daily anti tuberculosis treatment. This case shows us the importance of imaging as a diagnostic tool and as an alternative for laparoscopy in COVID-19 pandemic to diagnose abdomino-pelvic tuberculosis.
