Bilateral paramedian thalamic infarctions in a young woman with patent foramen ovale
Timocki medicinski glasnik(2016)
摘要
Background: Simultaneous bilateral thalamic infarctions are rare and in most cases associated with typical clinical pattern which, beside other things, include neuropsychological changes. Case report: We report a case of a 37- year-old woman with acute onset ofdiplopia from skew deviation, right-sided central facial nerve palsy, left hemihypesthesia, ataxia, with normal level of consciousness and without any neuropsychological disturbances except minor memory deficit. She was diagnosed with bilateral thalamic infarction due to the cardioembolisation via patent foramen ovale. Conclusion: In cases of bilateral thalamic infarction one can presume the existence of rare anatomic variant of thalamic perfusion commonly known as the artery of Percheron, single artery trunk that branches to irrigate both paramedian territories of thalamus. The cause of infarction can be cardioembolism trough the patent foramen ovale, especially in young adults. Our case represents a combination of two specific pathological conditions - patent foramen ovale and bilateral thalamic infarction. Clinical presentation in this case was unusual for the bithalamic paramedian infarction.
