Objective To analyze the diagnosis of intracranial malignant melanoma. Methods Ten cases of melanoma without definite primary extracranial lesions were reported and their epidemiological characteristics, clinical symptoms, signs and imaging data were analyzed. Results The results showed that the clinical symptoms and signs were similar to those of brain tumors and intracerebral hemorrhage. However, the course of disease was short. Two cases were accompanied by skin mole. The density of CT scan was more common in tumors. MRIT1WI mostly showed high signal and T2WI low signal , With significant enhancement, often accompanied by stroke; pathological malignant melanoma; preoperative misdiagnosis in 8 cases (80%). Conclusion To comprehensively analyze the epidemiology, clinical manifestations, extracranial signs and imaging features of the disease to improve the preoperative diagnosis
