目的　探讨少见的颅内原发恶性淋巴瘤的临床规律与影像特征。方法　总结分析经手术后病理证实的 2 7例颅内原发恶性淋巴瘤的临床规律与影像特点 ,其中全部病例行CT扫描 ,2 0例同时进行CT及MRI检查。结果　临床大多以头痛为首发症状 ,其次为癫痫发作、头晕、偏瘫等 ,40岁左右男性多发 ,幕上多见。CT平扫病灶多呈等或高密度 ,MRI上T1WI绝大多数呈等或稍低信号 ,而T2 WI多接近灰质信号。增强扫描肿瘤明显均匀强化 ,约 1/3病灶中央可有囊变坏死 ,可单发或多发。结论　结合临床及影像学改变 ,对原发性颅内恶性淋巴瘤可提出较准确的临床诊断

Objective To investigate the clinical features and imaging features of rare intracranial primary malignant lymphoma. Methods The clinical features and imaging features of 27 cases of primary intracranial malignant lymphomas confirmed by pathology were analyzed. Among them, CT scan was performed in all cases and CT and MRI were performed in 20 cases at the same time. Results Most of the clinical headache as the first symptom, followed by seizures, dizziness, hemiplegia, etc., 40-year-old men, multiple, more common on the screen. CT scan lesions were mostly equal or high density, MRI T1WI vast majority of equal or slightly lower signal, and T2 WI more close to gray signal. Enhanced scan of the tumor was significantly enhanced, about 1/3 of the central lesion may have cystic degeneration, single or multiple. Conclusion Combined with clinical and radiological changes, the diagnosis of primary intracranial malignant lymphoma can be more accurate clinical diagnosis
