Tuberculosis is still a common problem in immigrant population with peritoneal tuberculosis as the most common presentation of extrapulmonary disease.
A 36-year-old woman presented with abdominal distention, night sweats and weight loss. Physical examination and radiologic studies revealed ascites, omental caking and bilateral enlarged ovaries with an elevated serum Ca-125 of 353 U/mL. Acid-fast stain and culture were negative for Mycobacterium tuberculosis. Diagnostic laparoscopy and biopsy revealed multiple granulomas with epithelioid cells and caseification necrosis confirming tuberculosis. Treatment with anti-tuberculin drugs resulted in resolution of symptoms with a reduction in Ca-125 to normal.
Laparoscopic biopsy with frozen section evaluation would spare patients with peritoneal tuberculosis from unnecessary extensive surgery. Serum Ca-125 level may be useful in monitoring treatment response.
