[A case of tuberculous mesenteric lymphadenitis and peritonitis with symptoms of acute abdomen].

Both of tuberculous mesenteric lymphadenitis and tuberculous peritonitis are now rather rare in parallel with the decrease of the incidence of tuberculosis as a whole. Here, we report a case of tuberculous mesenteric lymphadenitis complicated with tuberculous peritonitis. A 28-year-old man was admitted to our hospital with pulmonary tuberculosis. Antituberculous chemotherapy was started and his chest X-ray findings were improved. After 11 weeks of the treatment, high fever of 39.0 degrees C developed suddenly and he complained right lower abdominal pain. During laparotomy performed on suspicion of acute appendicitis, swelling of mesenteric lymph-nodes, numerous miliary tubercles on mesentery and turbid ascites were noticed. Diagnoses of tuberculous mesenteric lymphadenitis and tuberculous peritonitis were confirmed by bacteriological and histological examinations of lymph-nodes and tubercles. Ileocecal resection was performed and clinical course after the surgery was favourable.
