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.
