[Musical hallucinosis following infarction of the right middle cerebral artery].
A 44-year-old woman demonstrated a musical hallucinosis four months after a massive infarction in the territory of the right middle cerebral artery. This musical hallucinosis consisting of familiar tunes, was continuous and perceived by both ears. Magnetic Resonance Imaging, middle and late auditory evoked potentials suggested that right Heschl's gyrus and associative areas were imparied. Audiometry demonstrated a low right transmission deafness. The hallucinosis was persistent for seven months and stopped just after hemorrhage of the right ear. This case gives the opportunity to review the different mechanisms responsible for musical hallucinosis.
