| 目的 分析椎管内节细胞神经瘤的MRI征象，以提高术前诊断能力。方法 回顾性分析9例经手术病理证实、累及椎管的节细胞神经瘤MRI资料，观察肿瘤位置、形态、大小、信号和强化程度等。结果 共纳入9个病灶，其中位于颈椎4个，胸椎2个，腰骶椎3个；7个累及椎管内外，呈哑铃状，2个位于椎间孔区，呈结节状；9个病灶T2WI均呈均匀或不均匀高信号，1个病灶内见囊变坏死。8个接受增强扫描的病灶中，3个呈明显强化，5个呈轻中度强化，4个病灶内见条状强化。所有病灶均伴有受累椎间孔扩大，但骨质未见破坏。结论 椎管内节细胞神经瘤MRI表现具有一定特征性，有助于术前准确诊断。 |

| Objective To analyze MRI features of intraspinal ganglioneuroma, in order to improve the ability of preoperative diagnosis. Methods MRI data of 9 patients of intraspinal ganglioneuroma confirmed pathologically were analyzed retrospectively. The location, morphology, size, signal intensity and degree of enhancement of these lesions were observed. Results Totally 9 lesions were enrolled. Four lesions occurred in the cervical spine, 2 in the thoracic spine and 3 in the lumbosacral spine. Seven lesions were dumbbell shaped, involving both intra and extra-canalicular, and 2 lesions present as nodules in the foramen. All the lesions demonstrated homogeneous or heterogeneous high signal on T2WI, with only 1 lesion showed cystic change and necrosis. Contrast-enhanced scanning was performed in 8 lesions, and marked enhancement was shown in 3 lesions, mild-moderate enhancement in 5 lesions. Strand-shaped enhancement took place in 4 lesions. The intervertebral foramina of all the lesions were enlarged, but without bone destruction. Conclusion Intraspinal ganglioneuroma has some characteristics on MRI, which may be helpful to accurate preoperative diagnosis. |
