We report the MR imaging findings in two patients with solitary craniocerebral plasmacytoma, a benign plasma cell tumor that can arise from the skull, the dura, or, rarely, the brain. In both patients, the lesion was extraaxial and nearly isointense with gray matter on T2-weighted MR images, and diffusely enhanced after administration of contrast material, bearing some similarities to meningioma. A diagnosis of solitary craniocerebral plasmacytoma should be considered when a mass with these imaging features is seen, because total excision may not be necessary for this radiosensitive tumor.
我们报告了两名孤立性颅脑浆细胞瘤患者的磁共振成像（MR）表现。孤立性颅脑浆细胞瘤是一种良性浆细胞肿瘤，可起源于颅骨、硬脑膜，或极少情况下起源于脑实质。两名患者的病变均位于脑外，在T2加权MR图像上与灰质信号近乎等强，注射对比剂后呈弥漫性强化，与脑膜瘤有一些相似之处。当发现具有这些影像学特征的肿块时，应考虑孤立性颅脑浆细胞瘤的诊断，因为对于这种对放疗敏感的肿瘤，可能无需进行全切。
