A case of inflammatory pseudotumor is described, in which CT revealed a hyperdense intraventricular lesion with a trapped temporal horn, and MR imaging showed decreased T1 and markedly hypointense T2 signal with homogeneously intense enhancement. Radiologically and grossly the tumor resembled a meningioma; however, histologically it was composed purely of inflammatory, nonneoplastic components. The lesion was resected with no evidence of recurrence at 5-month follow-up.
本文描述了一例炎性假瘤病例，其中CT显示脑室内高密度病变伴颞角受压，磁共振成像显示T1信号减低，T2信号明显低信号，强化均匀。影像学和大体表现上肿瘤类似脑膜瘤；然而，组织学上它完全由炎性非肿瘤成分组成。病变被切除，5个月随访无复发迹象。
