A case report on a 30-year old female patient who underwent resection of a haemangiopericytoma followed by radiation therapy in 1988 is presented. 6 months ago a space-occupying lesion was detected within the radiation field, which was classified as a plexiform fibrohistiocytic tumour (PFT). On MRI PFT showed the similar signal intensities as the muscles in T1, as well as T2-weighted images. After gadolinium-DTPA no enhancement within the tumour could be measured. Based on its exclusively dermal and subcutaneous location, and its signal behaviour uncommon for a malignant soft tissue mass, PFT must be included in differential diagnosis in any examining for local tumour recurrence.
本文报告一例30岁女性患者，该患者于1988年接受了血管外皮细胞瘤切除术，随后接受放射治疗。6个月前，在放疗区域内检测到一个占位性病变，被分类为丛状纤维组织细胞瘤（PFT）。在MRI上，PFT在T1加权像和T2加权像上显示出与肌肉相似的信号强度。注射钆喷酸葡胺后，肿瘤内未检测到强化。基于其仅位于真皮和皮下的位置，以及其信号表现不同于恶性软组织肿块，在任何检查局部肿瘤复发时，PFT都必须列入鉴别诊断。
