Abdominal Tuberculosis: Utility of Laparoscopy in the Correct Diagnosis
- 411 Downloads
Abdominal tuberculosis is one of the most prevalent form of extra-pulmonary disease, and the diagnosis is difficult because of non-specific clinical features.
We presented a case of a Tunisian woman with cough, nausea, decreased appetite and pelvic-abdominal pain. CT scan showed peritoneal thickening, peritoneal tiny nodules and enlarged mesenteric lymph nodes ascitic fluid. Sputum analysis was negative. Abdominal paracentesis was performed, and no malignant cell was detected. The Ziehl staining revealed a negativity for acid-fast bacilli.
Diagnostic laparoscopy was performed. Biopsy specimens of peritoneum, liver, omentum and diaphragm showed omental epithelioid granulomas with a centrale caseous necrosis and Langhans giant cells. The patient received anti-tubercular treatment.
In case of suspicion of tuberculosis, when bacteriologic and cytologic analysis is negative, laparoscopy with biopsies is helpful for correct diagnosis and appropriate management.
