title: [Neurophysiology of pain in tentorial irritation: description of a case secondary to medulloblastoma].
abstract: We report the case of a 32-year-old woman who complained of dull and compressing occipital pain, with unilateral radiation to the left frontal and supraorbital areas (of the sickening type). The radiological, clinical, neurosurgical and neuropathologic investigation disclosed a medulloblastoma bulging and tickening the tentorium cerebelli. This case shows how mechanical stimuli of the structures innervated by the tentorial nerve can cause pain with characteristics of trigeminal and cervical involvement.
