A 39-year-old man with alcoholism for 20 years complained of fever, intermittent diffuse abdominal pain, and progressive abdominal distention for 2 weeks. Results of physical examination and abdominal sonography revealed ascites without jaundice. Results of acid-fast staining and polymerase chain reaction of the aspirated ascitic fluid, with numerous lymphocytes, were negative for any bacilli or Mycobacterium tuberculosis. Abdominal magnetic resonance imaging showed septate fluid-containing cavities and thickened peritoneum (Figure 1). Laparotomy revealed violin string–like fibrinous strands, white miliary nodules, and omental thickening (Figure 2).
