Extramedullary hemangioblastoma is a very rare entity that has been rarely reported in the literature.
A 17-year-old female presented with limping that rapidly progressed to paraparesis and urine incontinence over a one-month duration. Clinically, she had a small swelling on her spine. There was a diagnostic challenge when an enhanced magnetic resonance imaging (MRI) suggested dumbbell - shaped intradural extramedullary mass in the lower thoracic spine, hypointense on T1 and hyperintense on T2 sequences and heterointense on post contrast sequence. The radiologic differentials were pictures of nerve sheath tumors. However, histopathological examination of en bloc excisional biopsy showed hemangioblastoma with a differential of solitary fibrous tumor. Complete excision of the mass was done intraoperatively and the patient improved clinically.
Contrast-enhanced MRI and histopathologic correlation are important for evaluating these rare tumors.
髓外血管母细胞瘤是一种非常罕见的实体瘤，文献中鲜有报道。
一名17岁女性患者，起初表现为跛行，在一个月内迅速发展为双下肢轻瘫和尿失禁。临床上，她的脊柱有一个小肿块。增强磁共振成像（MRI）显示下胸椎硬膜内髓外哑铃形肿块，T1序列呈低信号，T2序列呈高信号，增强后序列呈混杂信号，这带来了诊断挑战。影像学鉴别诊断考虑为神经鞘瘤。然而，整块切除活检的组织病理学检查显示为血管母细胞瘤，需与孤立性纤维瘤鉴别。术中完整切除了肿块，患者临床症状改善。
对比增强MRI和组织病理学相关性对于评估这些罕见肿瘤很重要。
