A case of intracranial primary meningeal melanoma misdiagnosed as cortical venous infarction with hemorrhage.

Abstract

Intracranial primary melanoma is a rare and highly differentiated borderline or malignant tumor. The prognosis of tumors varies significantly depending on their location and resection range. Therefore, accurate diagnosis before surgery together with complete resection of the tumor as much as possible and adjuvant chemoradiotherapy is the key to improve the prognosis of patients. Imaging is important for preoperative diagnosis. The tumor in the patients was dominated by pial meningeal lesions. It was obviously uneven after MRI enhancement, and there was no obvious low T2WI signal. It is not easy to distinguish it from cortical venous infarction with hemorrhage. Moreover, the tumor often shows different imaging manifestations due to the different melanin contents, and it is easy to be misdiagnosed before operation. The final diagnosis depends on pathological and immunohistochemical examination.
