摘要

目的：分析结节型脑膜转移瘤的CT影像表现及探讨结节型脑膜转移瘤的组织来源。方法：回顾性分析35例经手术病理、穿刺活检或CSF细胞学检查阳性证实为结节型脑膜转移瘤的病例，每例进行CT常规平扫和增强扫描。结果：35例结节型脑膜转移瘤的CT影像表现为位于颅骨内板下密度均匀的高密度影，边缘清楚。结节型脑膜转移瘤分结节状脑膜转移瘤和团块状脑膜转移瘤2型，结节状和团块状脑膜转移瘤伴颅骨破坏分别为6例（6/27，22.22%）和5例（5/8，62.50%），差异有统计学意义（P＜0.05）；结节状和团块状脑膜转移瘤为单发的脑膜转移瘤分别为5例（5/27，18.52%）和5例（5/8，62.50%），差异有统计学意义（P＜0.05）；并且结节状脑膜转移瘤和团块状脑膜转移瘤组织来源有明显不同。结论：结节型脑膜转移瘤CT影像表现具有特征性，CT是结节型脑膜转移瘤的重要检查方法。

Abstract

Objective: To analyze the CT imaging manifestations and investigate the origination of nodular meningeal carcinomatosis(NMC). Methods: Thirty-five cases with NMC confirmed by operation and pathology or positive CSF examination were analyzed retrospectively. All cases were examined by plain and contrast CT. Results: CT imaging manifestations of NMC: the lesions were homogeneously high density shadows under the inner table of the skull, the edge of the lesion was well-defined, the lesions enhanced markerly on contrast CT scan. NMC divided into tubercular meningeal carcinomatosis(TMC) and mass-like meningeal carcinomatosis(MMC), there were 5(5/8, 62.50%) patients accompanied with destruction of the skull in MMC group, while only 6(6/27, 22.22%) in TMC group(P＜0.05), the solitary meningeal carcinomatosis of patients in 5 cases(5/27, 18.52%) in TMC was lower than that of in 5(5/8, 62.50%) in MMC group(P＜0.05). There were obvious differences of the origination in TMC and MMC. Conclusion: CT imaging manifestations was characteristic of NMC, CT was an important examination method for NMC.
