Tuberculosis Pulmonar y Extrapulmonar. Reporte de un caso

espanolLa tuberculosis representa alta morbilidad y mortalidad infantil, con mayor incidencia en lactantes y adolescentes. Las manifestaciones clinicas en el nino son inespecificas, en algunos casos estan ausentes, lo que retrasa el diagnostico, que depende del aislamiento, identificacion microbiologica y cultivo del Mycobacterium, reportando 13.5% y 40% respectivamente, lo que hace dificil su confirmacion bacteriologica en lactantes. Se describe caso de lactante con desnutricion cronica, que ingresa por sindrome adenomegalico y evacuaciones liquidas, presentando clinica inespecifica, radiografia de torax sugestiva de neumonia, que no mejora con antibioticoterapia, en tomografia de cuello con contraste, multiples plastrones adenomegalicos cervical y supraclavicular bilateral, por lo que se buscaron otros agentes etiologicos. A pesar de resultado negativo de prueba de tuberculina se inicia tratamiento antituberculoso, con buena evolucion clinica. Reporte final de contenido gastrico y cultivo positivo para tuberculosis, y biopsia ganglionar con diagnostico anatomopatologico de infeccion por Mycobacterium tuberculosis. EnglishTuberculosis represents high morbidity and infant mortality, with a higher incidence in infants and adolescents. The clinical manifestations in the child are nonspecific, in some cases they are absent, which delays the diagnosis, which depends on the isolation, microbiological identification and culture of the Mycobacterium, reporting 13.5% and 40% respectively, which makes its bacteriological confirmation in infants difficult . A case of infants with chronic malnutrition, who are admitted due to adenomegalic syndrome and liquid evacuations, presenting a nonspecific clinic, chest radiography suggestive of pneumonia, which does not improve with antibiotic therapy, in contrast tomography, multiple cervical adenomegalic plastrons and bilateral supraclavicular, is described. Therefore, other etiological agents were sought. Despite a negative tuberculin test result, tuberculosis treatment is initiated, with good clinical evolution. Final report of gastric contents and positive culture for tuberculosis, and lymph node biopsy with pathological diagnosis of Mycobacterium tuberculosis infection.
