RESUMO
The occurrence of disseminated tuberculosis in combination with acute leukemia is rare. A 28 year old male undergoing induction chemotherapy for AML presented with fever of unknown origin. Upon the studies to make the diagnosis this case turned out to be disseminated tuberculosis including meningitis. The chest CT showed multiple enlarged mediastinal lymphadenopathy. The Brain CT showed noncommunicating obstructive hydrocephalus. Disseminated tuberculosis was pathologically proven by theliver, bone marrow and mediastinal lymph node biopsies. As clinical course improved, radiological lesions were completely resolved after antituberculosis therapy. It is important to consider disseminated tuberculosis for the etiology of FUO inpatient with AML who had suffered from long standing fever.
