BACKGROUND
Brain infarction secondary to stenosis of the posterior cerebral artery is uncommon. We report a patient with midbrain infarction and symptoms of both Benedikt's and pupil-sparing oculomotor palsy syndromes secondary to posterior cerebral artery stenosis.
CASE DESCRIPTION
A 51-year-old woman developed diplopia, left ptosis, and right hemiataxia and hyperactive tendon reflexes. Pupils were equal and reactive. Radiological examination revealed stenosis of the posterior cerebral artery and left-sided midbrain infarct.
CONCLUSIONS
Stenosis of the posterior cerebral artery may cause only midbrain infarction and may be responsible for Benedikt's and pupil-sparing oculomotor palsy syndromes.
背景
大脑后动脉狭窄继发脑梗死并不常见。我们报告一例因大脑后动脉狭窄继发中脑梗死且出现 Benedikt 综合征和瞳孔保留动眼神经麻痹综合征症状的患者。
病例描述
一名 51 岁女性出现复视、左侧上睑下垂、右侧半身共济失调和腱反射亢进。双侧瞳孔等大且对光反射灵敏。影像学检查显示大脑后动脉狭窄及左侧中脑梗死。
结论
大脑后动脉狭窄可能仅导致中脑梗死，并可能引发 Benedikt 综合征和瞳孔保留动眼神经麻痹综合征。
