[Bilateral middle cerebellar peduncle infarcts caused by bilateral vertebral artery occlusion: a case report].

Patients with bilateral vertebral artery occlusion have a high incidence of cerebral infarction with poor prognosis. Infarction of bilateral middle cerebellar peduncle (MCP) is extremely rare and only a few cases have been reported in literature. A 74-year-old male patient was admitted to our hospital with a chief complaint of dizziness and walking instability for 13 d. Brain magnetic resonance image showed acute bilateral middle cerebellar peduncle infarction. Digital subtraction angiography showed occlusion of the initiation part of left vertebral artery and whole right vertebral artery, while a large amount of collateral circulations and recanalization were observed. After volume expansion, anti-platelet aggregation and lipid-lowering therapy, the symptoms disappeared. The patient was followed up for 10 months and he recovered well.
