Intracerebral malignant melanoma presenting as an Arteriovenous Malformation: case report and literature review

Background: The authors introduced a rare case of intracranial malignant melanoma. Case presentation: A 32 year-old male patient presented to the hospital with signs and symptoms commonly seen in the presentation of a hemorrhagic stroke. The patient was diagnosed as having an Arteriovenous Malformation (AVM) after a thorough history, physical examination and radiographic imaging were performed and assessed. However, intraoperative findings and postoperative histopathology findings revealed that the supposed AVM was in fact a malignant melanoma, appearing as an AVM of the brain, on radiographic imaging. Conclusion: After reviewing related literature, our team realized that it was a rare finding for a melanoma pretending as a brain AVM.
