We aimed to demonstrate the use of neuroimaging studies in vascular compression of the oculomotor nerve.
A 24-year-old woman was noted by her dentist to have anisocoria, with the left pupil being larger than the right. After detailed ophthalmologic and neurological examination, we proceeded to perform neuroimaging. T2-weighted images (2 mm) and constructive interference in steady-state (0.3 mm) images were utilized.
Magnetic resonance imaging showed that duplicated left superior cerebellar artery, a prominent posterior communicating artery, and a posterior cerebral artery combined to compress the superomedial portion of the left oculomotor nerve.
With continued improvements in neuroimaging, we think that more cases of isolated cranial neuropathies previously labeled as "idiopathic" will be shown to result from vascular compression.
我们旨在证明神经影像学研究在动眼神经血管压迫中的应用。
一名24岁女性被牙医发现有瞳孔不等大，左侧瞳孔大于右侧。经过详细的眼科和神经科检查后，我们进行了神经影像学检查。使用了T2加权图像（2毫米）和稳态构成干扰图像（0.3毫米）。
磁共振成像显示，左侧小脑上动脉重复、后交通动脉突出以及大脑后动脉共同压迫左侧动眼神经的上内侧部分。
随着神经影像学的不断改进，我们认为更多以前被标记为“特发性”的孤立性颅神经病变病例将被证明是由血管压迫引起的。
