Objective. Progressive multifocal leukoencephalopathy (PML) is a demyelinating infectious disease that occurs in patients with HIV at the AIDS stage. It is characterized by multifocal lesions in the cerebral white matter that produce neurological and ophthalmological manifestations mimicking a space-occupying lesion without being one. The coexistence of other conditions may complicate the differential diagnosis. We report a case in which an interdisciplinary assessment led to the identification of advanced glaucoma as the main cause of visual loss.
Case Report. A male patient presented with progressive visual acuity loss. During history taking, hindered by marked cognitive and language impairment, he reported a previous hospitalization for altered sensorium, during which he had been diagnosed with PML secondary to HIV infection in the AIDS stage. Comprehensive neurological and ophthalmic evaluations confirmed advanced glaucoma as the underlying ocular disease responsible for the visual decline.
Conclusion. This case highlights the diagnostic and therapeutic challenges that arise when cognitive or language disorders interfere with the doctor–patient relationship. Accurate identification of the visual deficit’s etiology in complex neurological contexts is crucial to prevent misdiagnosis and guide appropriate management.
