目的总结7例误诊为胶质瘤的脱髓鞘假瘤(DPT)的临床病理及影像学特点,以提高对本病认识。方法回顾性分析7例DPT临床病理学及影像学。结果 7例术前影像学及临床怀疑为胶质瘤,术后病理诊断为DPT;1例在外院手术,冰冻及常规病理诊断为星型细胞瘤,最后在我院重切腊块并行免疫染色诊断为DPT。结论 DPT极易误诊为胶质瘤,提高对其不典型影像学认识,并结合临床是降低误诊的关键,对难以分辨者,可给予激素进行诊断性治疗,避免不必要的手术。
Objective To summarize the clinicopathological features and radiological features of seven deratomized pseudotumor (DPT) misdiagnosed as gliomas in order to improve the understanding of this disease. Methods Retrospective analysis of 7 cases of DPT clinical pathology and imaging. Results 7 cases of preoperative imaging and clinical suspected glioma, postoperative pathological diagnosis of DPT; 1 case of surgery in the outpatient, frozen and routine pathological diagnosis of astrocytoma, and finally in our hospital paraffin blocks parallel immunostaining Diagnosed as DPT. Conclusions DPT can be easily misdiagnosed as glioma, which enhances its atypical imaging knowledge. Combined with clinical treatment is the key to reduce misdiagnosis. It is difficult to distinguish those who can be given hormone diagnostic treatment, to avoid unnecessary surgery.
