Peritoneal Chlamydia trachomatis Infection as a Cause of Ascites: A Diagnosis Not to Be Missed.

Ascites is a common complication of several conditions, but it is rare in cases of Chlamydia trachomatis infection. We report a 36-year-old patient presenting with abdominal swelling for a week prior to hospitalization. An extensive workup excluded liver or heart disease and malignancy. A computed tomography scan demonstrated massive ascites and severe thickening of peritoneal reflections. Laboratory tests showed low serum-ascites albumin gradient, high total protein, and low adenosine. Diagnostic laparoscopy revealed inflammatory signs of both fallopian tubes. The histopathological results from peritoneal biopsy were consistent with lymphoid proliferation with reactive lymphoplasmacytic infiltrate. A gynecological investigation showed a positive DNA for C. trachomatis in the cervical swab. After treatment with doxycycline, there was a complete resolution of ascites.
