脑原发性恶性淋巴瘤(Prmary MalignantCerebral Lymphoma)非常少见,占中枢神经系统原发肿瘤的0.5%～1.2%,约占颅内肿瘤的0.3%～2%。由于本病缺乏特征性表现,临床及放射学诊断历来较为困难。本文报告4例,临床及 CT 均误诊,后经手术与病理证实为脑原发性恶性淋巴瘤。
Primary malignant lymphoma (Prmary MalignantCerebral Lymphoma) is very rare, accounting for 0.5% to 1.2% of primary tumors of the central nervous system, accounting for about 0.3% to 2% of intracranial tumors. Due to the lack of characteristic features of this disease, clinical and radiological diagnosis has always been more difficult. This article reports 4 cases, clinical and CT are misdiagnosed, after surgery and pathology confirmed as primary brain malignant lymphoma.
