RESUMO
Meningitis or meningoencephalitis are the most common presentations of Koch bacilli infection on the central nervous system (CNS), especially in immunosuppressed patients, in whom the bacilli normally reaches the meninges and the cerebral parenchyma.. A least common pathological presentation is the tumoral growth pattern disease known as tuberculoma. This pathological entity is more common in the cerebral hemispheres and is rarely located in the brainstem. The present case report describes a case of a 55-year-old patient under regular antiretroviral therapy who was hospitalized with signs of brainstem and cerebellar disturbances. Computed tomography (CT) and magnetic resonance imaging (MRI) of the brain showed an exophytic lesion in the dorsal region of the pons. The patient underwent total resection of the lesion and the histopathologic analysis was consistent with a tuberculoma.

Cystic lesions inside the brain parenchyma are a common pathological finding in the investigation of patients with suspicion of cerebral tumor. Histological diagnosis is important to guide the patient's treatment and follow-up, and to determine prognosis. Among patients diagnosed with cerebral cysts, most are located in the parenchyma above the tentorium. The authors describe the case of a patient who had been suffering from dizziness and balance disturbance for 4 months; the investigation identified a cyst inside the cerebellar right hemisphere. A surgical procedure was performed, and the biopsy microscopic analysis diagnosis was glial cyst.
Patologias intraparenquimatosas de características císticas são comumente identificadas em pacientes que estão sob investigação de neoplasias cranianas. Lesões císticas são mais prevalentes acima da tenda cerebelar, e o diagnóstico histológico é fundamental para determinar o tratamento, seguimento e prognóstico do paciente. Os autores relatam o caso de um paciente com sintomas de vertigem e alteração no equilíbrio dinämico de 4 meses de evolução, cuja investigação diagnosticou cisto intraparenquimatoso no hemisfério cerebelar direito. Procedeu-se com intervenção cirúrgica cujo diagnóstico histopatológico foi compatível com Cisto Glial
