摘要

良性增强大孔病变先前被描述为T2高信号小的、位于硬膜内椎动脉后方的增强病变。我们提出了第一个具有病理相关性的病例。这些病变是附着在脊髓副神经上的纤维结节。虽然在随后的检查中，它们可以随着时间的推移而扩大，但根据成像特征和位置，它们不需要手术切除。

Benign Enhancing Foramen Magnum Lesions.

Benign enhancing foramen magnum lesions have been previously described as T2-hyperintense small, enhancing lesions located posterior to the intradural vertebral artery. We present the first case with pathologic correlation. These lesions are fibrotic nodules adhering to the spinal accessory nerve. While they can enlarge with time on subsequent examinations, on the basis of the imaging characteristics and location, they do not necessitate surgical resection.
