We report on an unusual tumor of the jugular foramen in a 26-year-old male. The lesion showed moderate enhancement on CT scan and a higher signal intensity on T2-weighted MR images than on T1, with a massive enhancement after gadolinium. Tumor was entirely removed surgically and histology was consistent with a low-grade myxoid chondrosarcoma, an exceptional tumor in this location. The differential diagnosis includes paragangliomas, schwannomas, metastases and meningiomas. Radiological and histological features can also mimic chordomas. However, immunohistochemical analysis certifies the diagnosis.
我们报告了一例26岁男性患者的颈静脉孔罕见肿瘤。该病变在CT扫描上表现为中度强化，在T2加权磁共振图像上的信号强度高于T1加权图像，注射钆剂后有明显强化。肿瘤通过手术完全切除，组织学检查结果与低级别黏液样软骨肉瘤相符，这是该部位罕见的肿瘤。鉴别诊断包括副神经节瘤、神经鞘瘤、转移瘤和脑膜瘤。影像学和组织学特征也可能类似脊索瘤。然而，免疫组化分析证实了诊断。
