A 36-year-old woman with a history of hydat ic cyst complained about abdominal quadrant pain with fever, night sweats and chills. Physical examination did not find any jaundice or fever. Biological tests were normal. Abdominal ultrasound showed a hypo-echoeic mass in segment VII of the liver. This mass measured 4x3 cm and abdominal computed tomography confirmed the presence of a hypodense mass with a peripheral enhancement of segment VII segment of the liver. Hydatic serology was negative. Upper gastrointestinal endoscopy, colonoscopy, thoraco-abdominal computed tomography scan and pelvic examination did not show anything of interest. Percutaneous ultrasound guided biopsy was negative. No anaphylactic reaction occured during the biopsy. The decision was made to operate. As a liver abcessed tumor was discovered per-operatively, in contact with the diaphragm, a resection of the mass was conducted. Histological examination led to a diagnosis of hepatic tuberculosis. The patient received anti-bacillary antibiotics and the clinical and radiological outcomes were expected to be positive.
