Pelvic tuberculosis (TB) in pregnancy and puerperium is rare. Its atypical presentation as puerperal shock is more rare. We describe a case of pelvic TB that manifested as shock in a teenager who was two weeks postpartum. She failed to respond to antibiotics. Ziehl-Neelsen staining of aspirated pus from the left fossa collection in the abdominal cavity was positive for mycobacterium TB. Prompt treatment with antitubercular therapy could save patients from this life-threatening condition.
