Parietal Wall Abscess Perforating to Transverse Colon: A Rare Presentation

Extrapulmonary tuberculosis affects an isolated organ or presents secondary to pulmonary involvement. Lymph nodes are the common sites for extrapulmonary tuberculosis. Primary extrapulmonary tuberculosis involving parietal wall is an unusual presentation. Tubercular abscess of the abdominal wall perforating to large bowel has not been reported. Here, we are reporting a very rare case of anterior abdominal wall abscess of tubercular origin in a 57-year-old female patient who presented with complaints of pain in upper abdomen for four months. CT scan and intraoperative findings revealed perforation of the abscess into transverse colon. Histopathology report confirmed the aetiology and origin of the abscess.
