Bilateral thalamic infarction and DSA demonstrated AOP after thrombosis
نویسندگان
چکیده
Bilateral paramedian thalamic stroke is a special ischemic pattern that results from occlusion of the artery of Percheron (AOP), a rare anatomic variant of the paramedian arteries. We report a case of bilateral thalamic infarctions, with a dramatic improvement after thrombolysis. DSA demonstrated recanalization of AOP with possible unreported variation.

BACKGROUND AND PURPOSE Occlusion of the AOP results in a characteristic pattern of ischemia: bilateral paramedian thalamus with or without midbrain involvement. Although the classic imaging findings are often recognized, only a few small case series and isolated cases of AOP infarction have been reported. The purpose of this study was to characterize the complete imaging spectrum of AOP infarct...

Acute bilateral paramedian thalamic and mesencephalic infarcts are uncommon. Occlusion of the artery of Percheron (AOP) is presumed to cause this specific stroke syndrome. However, occlusion of the AOP is rare and early diagnosis is challenging. Here we described a 70-year-old male patient who presented with acute disturbance of consciousness due to acute bilateral paramedian thalamo-mesencepha...

The artery of Percheron (AOP) infarction always manifests as paramedian bilateral thalamic infarcts and might present as paramedian midbrain infarcts. Despite the limited MRA evaluation, due to small size of the artery, careful evaluation of the patient's history, the clinical presentation with imaging findings can facilitate the proper diagnosis.
