A patient had an intracranial solitary extraskeletal plasmacytoma (SEP). To date, only 12 similar cases have been reported in the English literature. This report includes the first description of computed tomographic findings in a patient with intracranial SEP. There is a striking similarity between the features of intracranial SEP and meningiomas. A detailed comparative study of the features of these two neoplasms was done. The findings indicate that the age and sex distribution, clinical features, location of the tumors, roentgenographic findings, and even the gross pathologic nature of the two neoplasms are very similar. The course and prognosis, however, are probably different. Intracranial SEP, although rare, should be included in the differential diagnosis of brain tumors that arise in areas where meningiomas commonly arise.
一名患者患有颅内孤立性骨外浆细胞瘤（SEP）。迄今为止，英文文献中仅报道了12例类似病例。本报告首次描述了颅内SEP患者的计算机断层扫描结果。颅内SEP的特征与脑膜瘤有显著相似之处。对这两种肿瘤的特征进行了详细的比较研究。研究结果表明，这两种肿瘤的年龄和性别分布、临床特征、肿瘤位置、X线表现，甚至大体病理性质都非常相似。然而，其病程和预后可能不同。颅内SEP虽然罕见，但在脑膜瘤常见发生区域出现的脑肿瘤鉴别诊断中应予以考虑。
