Resumo
Este artículo presenta el caso de un hombre mayor que ingresó con cuatro meses de evolución de hemiparesia izquierda progresiva con sospecha de etiología neoplásica. Se le realizó una biopsia cerebral estereotáctica que reveló lesiones granulomatosas con estructuras micóticas intracelulares compatibles con histoplasma. Adicionalmente, el paciente había requerido una orquidectomía debido a una masa testicular con una biopsia que evidenció lesiones granulomatosas. La prueba del VIH y la carga viral fueron negativas, el recuento de linfocitos CD4+ fue inferior a 300 células/µl, y fue positiva la reacción en cadena de la polimerasa para M. tuberculosis en el tejido testicular. Se realizó un nuevo recuento de linfocitos T CD4+ después de seis semanas del diagnóstico que nuevamente fue inferior a 300 células/µl, lo cual confirmó el diagnóstico de linfocitopenia T idiopática de CD4+.
