Bilateral medial medullary infarction.

We report a case of a 42-year old man with a bilateral medial medullary str oke (MMS) with favorable outcome. First described by Spiller in 1908, the M MS accounts for less than 0,5% of all cerebral infarcts. It may be unilater al or more rarely bilateral, and may often be the consequence of the athero sclerosis. The clinical features of MMS classically associate contralateral hemiparesis and lemniscal hypoesthesia accompanied by ipsilateral lingual palsy and sometimes oculomotor disturbances (upbeat nystagmus). With the ad vent of magnetic resonance imaging, some restricted or unusual clinical man ifestations can be attributed to this localization. The benign form of MMS seems much more common than MMS with poor prognosis.
