Solitary fibrous tumors are primary mesenchymal tumors, which may occur in any part of the body. Overall, these tumors are considered to have intermediate malignant potential with 5- and 10-year metastasis-free and overall disease-specific survival rates of 74% and 55%, and 89% and 73%, respectively (Demicco et al, 2012). Herein we present an unusual case of solitary fibrous tumors involving the ischioanal fossa in a 19-year-old woman with radiologic-pathologic correlation. This case was complicated by extensive tumor vascularity and was thus managed with preoperative embolization followed by en bloc surgical resection.

孤立性纤维瘤是原发性间叶组织肿瘤，可发生于身体的任何部位。总体而言，这些肿瘤被认为具有中等恶性潜能，5年和10年无转移生存率及疾病特异性总生存率分别为74%和55%，以及89%和73%（德米科等人，2012年）。在此，我们报告一例罕见的孤立性纤维瘤病例，该病例发生于一名19岁女性的坐骨肛门窝，并进行了放射学与病理学相关性分析。该病例因肿瘤血管丰富而复杂化，因此先进行术前栓塞，然后行整块手术切除。
