A 65-year-old man with infratentorial diffuse encephalopathy and hydrocephalus

Tuberculous encephalopathy （TBE） is an important diagnosis in countries with a high prevalence of tuberculosis. TBE is a life-threatening condition but rarely reported in the modern literature. We reported a case of a man with extensive parenchymal lesions involving the brainstem and right cerebellar hemisphere that resolved after treatment. The clinical, laboratory and pathological features of this case are highlighted and the pathogenesis is discussed.
