A 64-year-old female presented with hemangiopericytoma arising from a dural fascia graft placed after a previous operation for the total removal of a benign meningioma. The patient also had multiple pulmonary metastases identified as hemangiopericytoma. The tumor resected at the first operation was benign based on all grading systems for meningiomas. We considered that the tumor was a kind of scar tumor. The hemangiopericytoma probably developed from a scar tumor at the graft. We emphasize the importance of long-term follow-up for patients who have undergone surgery for benign tumors.
一名64岁女性，因先前手术全切良性脑膜瘤后植入的硬脑膜筋膜移植物发生血管外皮细胞瘤而就诊。该患者还发现有多处肺转移，病理证实为血管外皮细胞瘤。根据所有脑膜瘤分级系统，首次手术切除的肿瘤为良性。我们认为该肿瘤是一种瘢痕性肿瘤。血管外皮细胞瘤可能由移植物处的瘢痕性肿瘤发展而来。我们强调对接受过良性肿瘤手术的患者进行长期随访的重要性。
