This case report describes clinical, surgical, MR, and pathologic findings of an intraventricular fibroma, a rare, benign mesenchymal neoplasm. Relatively isointense with normal brain parenchyma on T1-weighted images, the tumor exhibited hyperintense signal on T2-weighted pulse sequences and enhanced intensely and homogeneously after intravenous administration of gadopentetate dimeglumine. Choroid plexus papilloma/carcinoma, meningioma, ependymoma, and subependymal giant cell astrocytoma should be included in the differential diagnosis.
本病例报告描述了一例脑室内纤维瘤的临床、手术、磁共振成像（MR）及病理检查结果，脑室内纤维瘤是一种罕见的良性间叶性肿瘤。在T1加权图像上，该肿瘤与正常脑实质信号相对等，在T2加权脉冲序列上呈高信号，静脉注射钆喷酸葡胺后呈明显且均匀强化。鉴别诊断应包括脉络丛乳头状瘤/癌、脑膜瘤、室管膜瘤和室管膜下巨细胞星形细胞瘤。
