内耳性めまいが疑われた小脳梗塞の2症例 Two cases of cerebellar infarction with a suspicion of labyrinthine vertigo
Two patients were admitted to our hospital with a suspicion of labyrinthine vertigo. The first case, a 61-year-old male with a history of hypertension and diabetes mellitus, was suffered from rotatory vertigo. CT ofthe head region revealed no abnormalities. With a diagnosis of horizontal dextro-rotary mixed vertigo, he wasadmitted to our department. MRI revealed the presence of an infarction at the posterior inferior cerebellarartery (PICA); but ENG findings showed a left labyrinthine disorder. Case 2, a 56-year-old male, also had ahistory of hypertension and diabetes mellitus. He experienced rotary vertigo one week earlier. Meanwhile hedeveloped rotatory vertigo and right tinnitus, in addition to horizontal levo-rotatory mixed nystagmus. MRIindicated the presence of an infarction at the right PICA region. Those patients suffering from vertigo withbackground conditions such as hypertension are likely to suffer from cerebellar infarction.
