Abstract:
UNASSIGNED: Oculomotor nerve palsy is often associated with diabetes mellitus or caused by compression by a cerebral aneurysm. Here, we report a rare case of oculomotor nerve palsy caused by compression by the posterior cerebral artery (PCA).
UNASSIGNED: A 66-year-old woman suddenly developed diplopia and right blepharoptosis. Her symptoms suggested incomplete right oculomotor nerve palsy. Magnetic resonance imaging showed that a sharp curve in the right PCA had compressed the right oculomotor nerve. Microvascular decompression surgery was performed. Intraoperative findings showed that the P2 portion of the PCA had caused an indentation in the oculomotor nerve in the prepontine cistern. The transposition of the PCA with a prosthesis released the pressure. After the operation, her right blepharoptosis gradually improved. She had fully recovered by 48 days after the operation.
UNASSIGNED: Neurovascular compression (NVC) is recognized as the cause of hemifacial spasms, trigeminal neuralgia, and glossopharyngeal neuralgia. This case report demonstrated that NVC can also cause oculomotor nerve palsy. A high index of clinical suspicion can detect vascular compression of the oculomotor nerve. Prompt diagnosis and appropriate surgical management can achieve clinical improvement.
摘要:
动眼神经麻痹通常与糖尿病有关或由脑动脉瘤压迫引起。这里,我们报告了一例罕见的大脑后动脉(PCA)压迫引起的动眼神经麻痹。
一名66岁的女性突然出现复视和右上睑下垂。她的症状提示右眼球运动神经麻痹不完全。磁共振成像显示,右侧PCA的锐利曲线压缩了右侧动眼神经。行微血管减压手术。术中发现表明,PCA的P2部分引起了前脑池动眼神经的压痕。PCA与假体的移位释放了压力。手术后,她的右上眼睑逐渐好转。手术后48天,她已经完全康复。
神经血管压迫(NVC)被认为是半面肌痉挛的原因,三叉神经痛,和舌咽神经痛.该病例报告表明,NVC也可引起动眼神经麻痹。高临床怀疑指数可以检测动眼神经的血管压迫。及时诊断和适当的手术治疗可以实现临床改善。
