MELO, Valdinaldo Aragão de et al. Tuberculosis of the cystic duct lymph node. Braz J Infect Dis [online]. 2004, vol.8, n.1, pp. 112-114. ISSN 1678-4391. http://dx.doi.org/10.1590/S1413-86702004000100009.
Tuberculosis of the cystic duct lymph node associated with cholelithiasis is rare. We report a case of a 40 year-old woman with this pathology. She presented with anorexia, biliary colic, postprandial fullness and fever. Imaging studies revealed cholelithiasis and several visible portal lymph nodes. Cholecystectomy was performed and histopathological examination showed tuberculosis of the cystic duct lymph node without affecting the gallbladder. The presence of gallstones and lymphadenopathy in computed tomography, associated with persistent fever and symptoms that resemble cholecystitis, should cause suspicion of tuberculosis. However, diagnosis is usually achieved by microscopic appearance of caseating granulomas and isolation of Mycobacterium tuberculosis. The treatment in this case consisted of cholecystectomy and antitubercular chemotherapy.
