后颅窝室管膜瘤在组织学上被称为低度恶性肿瘤。尽管转移的特征是良性的,但仅报告了几次同时诊断为原发性肿瘤的患者的转移病例。间隔性转移或自发性第二远端肿瘤是非常罕见的,在大多数情况下,在原发性肿瘤切除术后几个月内被诊断出来。在这里,我们报告一个2级儿童PFE患者表现出20年的时间间隔,以第二个骶骨室管膜瘤。患者最初在10岁时被诊断为PFE,并接受了肿瘤切除和术后放疗。在20多岁时,患者出现基底动脉闭塞并发危及生命的鼻出血。溶栓后,患者出现骶骨1级大型粘液乳头状室管膜瘤伴马尾综合征样症状。在这里,我们提出了一个罕见的情况下,两个室管膜瘤与20年的时间间隔在同一个病人的复合合并症。
Posterior fossa ependymomas (PFEs) are designated histologically as low-grade neoplasms. Despite being characterised as benign, cases of metastasis have been reported only a few times with the patients concurrently diagnosed with the primary tumour. Interval drop metastasis or spontaneous second distal tumours are extremely rare and, in most cases, are diagnosed within a few months of primary tumour resection. Here, we report a patient with a grade 2 paediatric PFE exhibiting a 20-year interval to a second sacral ependymoma. The patient was initially diagnosed with a PFE at the age of 10 years and underwent tumour resection and postoperative radiotherapy. In their late 20s, the patient presented with basilar artery occlusion complicated by life-threatening epistaxis. Post-thrombolysis, the patient presented with a large sacral grade 1 myxopapillary ependymoma with cauda equina syndrome-like symptoms. Here, we present a rare case of two ependymomas with a 20-year interval in the same patient with compounding comorbidities.
