Objective To analyze the clinical data, imaging characters of intracranial melanoma and the keys to its diagnosis. Methods The clinical and imaging data of 5 patients with intracranial melanoma were analyzed retrospectively. The literatures related to the melanoma were reviewed, and its character on CT and MRI and diagnosis treatment were discussed. Results CT and MRI could show the size, location and number of the intracranial melanoma, but its manifestions on CT and MRI were of poor specificity. The signal intensity on MRI depended on the amount of melanian cells within the tumor. Three cases were preoperatively suspected to be metastatic tumor, meningioma and glioma respectively. Multiple lesions were found by preoperative imaging examination in 3 cases. Conclusion It is difficult to diagnose correctly intracranial melanoma, especially primary intracranial melanoma before the operation. Pathological examination can make the definite diagnosis in the patients with intracranial melanoma. The curative effect on the intracranial melanoma can be promisingly heightened by comprehensive treatment.
