We report a rare case of bilateral pericallosal artery ectasia with stenosis in a 49-year-old man complaining of frontal headache. CT showed a serpiginous calcified interhemispheric fissure lesion with contrast enhancement. Imaging of this lesion was pursued with MR and MR angiography; however, conventional cerebral angiography was needed to make a definitive diagnosis.
我们报告了一例罕见的双侧胼周动脉扩张伴狭窄病例，患者为一名49岁男性，主诉前额头痛。CT显示大脑镰间裂处有一蜿蜒状钙化病变，并伴有强化。对该病变进行了磁共振成像（MR）及磁共振血管造影（MRA）检查；然而，需要进行传统脑血管造影才能做出明确诊断。
