CA 125 and TB.

We present two unusual presentations of extrapulmonary tuberculosis (EPTB) and more specifically intra-abdominal tuberculosis (TB). These cases were initially suspicious for ovarian cancer, presenting with non-specific symptoms, ultrasound-confirmed ascites and elevated cancer antigen 125 tumour marker (CA 125). However, in both cases chest imaging demonstrated enlarged mediastinal nodes amenable to endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), which confirmed the diagnosis of TB. Both cases were successfully treated with quadruple TB therapy. © BMJ Publishing Group Limited 2021. No commercial re-use. See rights and permissions. Published by BMJ.
