Abstract：
Reports of cervical thymoma with myasthenia gravis are rare. In addition, 99mTc-MIBI (methoxyisobutylisonitrile:sestamibi) scintigraphy is a useful diagnostic examination for enlarged parathyroid tumours; however, there are a few reports of its accumulation in thymoma. Among them, there are no reports of cervical thymomas with 99mTc-MIBI accumulation complicated by myasthenia gravis. In this study, we performed surgery on a patient with preoperative myasthenic crisis accompanied by a cervical thymoma and a parathyroid tumour. Preoperatively, the cervical mass was determined to be a parathyroid tumour and was complicated by myasthenia gravis without thymic tumour. However, a pathological examination revealed that the cervical tumour with 99mTc-MIBI accumulation was a Type B2 thymoma, and a parathyroid tumour was identified in the vicinity. We report a very rare case in which symptoms improved with surgery.
摘要：
宫颈胸腺瘤合并重症肌无力的报道很少。此外,99mTc-MIBI（甲氧基异丁基异腈：Sestamibi）闪烁显像是一种有用的诊断检查甲状旁腺肿大的肿瘤；然而，有一些关于它在胸腺瘤中积累的报道。其中,无99mTc-MIBI累积并发重症肌无力的宫颈胸腺瘤的报道。在这项研究中,我们对一名术前肌无力危象伴有宫颈胸腺瘤和甲状旁腺肿瘤的患者进行了手术。术前,宫颈肿块被确定为甲状旁腺肿瘤，并伴有无胸腺肿瘤的重症肌无力。然而,病理检查显示99mTc-MIBI积聚的宫颈肿瘤为B2型胸腺瘤，在附近发现了甲状旁腺肿瘤。我们报告了一个非常罕见的病例，手术后症状得到改善。
