Pain was localized in the hypogastrium area for 3 months. The patient had menometrorrhagia, fever and shivering, and development ascites and diagnosis of pelvic mass required hospitalization.\nShe has been addicted to opium for 5 years and also used methadone. Her vital signs were stable and her lung sounds were clear but sometimes she had a fever of about 38. There was a 53×65 mm cyst in left ovary region in ultrasonography but the ovaries, uterus, liver, kidney and spleen were normal and ascites fluid was reported.\nAn ovarian malignant mass was reported in spiral CT scan (computerized axial tomography) with contrast. The patient underwent laparotomic surgery in which her uterine tubes were swollen with adhesion in both ovaries with multiple military peritoneal deposits. No mass has been observed in the abdomen and pelvis. The results of histologic examination demonstrated abdominal tuberculosis on her uterus, tubes, omentum, liver and intestinal surface. The results of laboratory test are shown in  table 1 . After surgery, she received anti-tuberculosis medical treatment using four drugs:  isoniazid,  pyrazinamide, ethambutol hcl and  rifampin.\n. Results of laboratory parameters in this patient\n\nAbdominal tuberculosis with series of clinical signs may mimic ovarian cancer ( 9 ). This often leads to unnecessary expensive surgery in women of reproductive age. However most cases can be diagnosed using a laparoscopy ( 10 ). CA 125  can be considered as a marker for the evaluation of treatment response. This patient shows rapid decline in CA 125  level paralleling clinical response to antituberculosis ( 11 ). For preoperative detection of tuberculosis, ascetic fluid adenosine (ADA) and PCR analysis have proven to be useful ( 12 ,  13 ). High level of ADA and the response after an antituberculosis regimen is helpful to avoid invasive diagnostic procedures which are potentially dangerous. In a study of 138 patients suspected to have ovarian malignancies, 5.7% of them showed ovarian tuberculosis after surgery. In these patients, pain and abdominal distension were usual presenting signs ( 12 ).\nAbnormal menstruation, pain, mass and distension of abdomen were the usual signs of 26 patients with ovarian malignancy diagnosed in a study in India that confirmed abdominal tuberculosis after laparoscopy and histopathology test ( 8 ). In addition, frozen section laparoscopy is a non-invasive method in diagnosis and it is suggested during surgery ( 13 ). Therefore, the presence of mass in abdomen, ascites and increasing of CA 125  may suggest the possibility of tuberculosis.\nIn conclusion, abdominal tuberculosis should be considered in the differential diagnosis of women with adnexal mass, ascites and elevated CA 125  even with negative cytology and bacteriological test results. The use of imaging techniques and laparoscopy or finally laparotomy is recommended. In endemic areas, physicians should consider tuberculosis in the differential diagnosis of any case with unusual manifestations.","source_license":"CC-BY-4.0","license_restricted":false}
