| 目的 探讨多发性脑胶质瘤(MCG)的MRI特点。 方法 对15例经手术病理证实MCG患者的MRI特点及病理学类型进行回顾分析。结果 15例患者共检出50个病灶,其MRI特点如下:①病灶数目不一,累及部位不同,以海马(海马旁回)最常受累(11/15,73.33%);②同一病例不同病灶的MRI信号特点及强化程度不同;③随访观察3例患者,各病灶进展程度亦各不相同;④病理类型以间变性星形细胞瘤最多见(10/15,66.67%)。结论 MCG的MRI表现有一定特征性;病灶的信号特点可在一定程度上反映其组织分化程度,分析其MRI特点对诊断该病有重要价值。 |

| Objective To investigate MRI features of multiple cerebral gliomas (MCG). Methods MR images of 15 patients with MCG confirmed surgically and pathologically were analyzed retrospectively. Results Totally 50 lesions were detected in 15 patients with MCG. MRI finding were as follows: ①The amount and location of lesions in different cases were variable, and hippocampus (hippocampal gyrus) were the most commonly involved area (11/15, 73.33%). ②Histological grades of lesions in every case were also variable and presented differential features of MRI signal and degree of enhancement. ③The progression of lesions in 3 followed-up cases was markedly different. ④Fifteen lesions were pathologically confirmed, and anaplastic astrocytoma was proved to be the most common histological type (10/15, 66.67%). Conclusion MRI findings of MCG have certain characteristic features that may reflect tissue differentiation of lesions and may play a valuable role in diagnosis of MCG. |
