Background: A rare neurological tumor i.e. primary meningeal melanocytoma; it may occur at the base of the brain, it is extremely rare at the anterior cranial fossa. Case & Result: A 24–year–old lady presented with headache, vomiting and blurring of vision at our radiotherapy department after surgery. Neurological exams were otherwise normal. CT Scan Brain and Contrast Enhanced MRI scan showed a heterogenous hyper intense lesion on T2 and isointense on T1 measuring 39x53 mm in left frontal lobe extending to basal ganglia. Mass displacing the midline and right ventricle was dilated. Prior to surgery, malignant glioma was diagnosed and near total excision was performed. On postoperative histopathological exam, the tumor proved to be a meningeal melanocytoma, WHO Grade–I. There was no skin melanoma was found but on the left side of the face and scalp nevus of Ota was diagnosed. After surgery, the patient received radiation therapy. Patient was normal after first follow up after radiation therapy. Conclusions: Our case of primary meningeal melanocytoma at the anterior cranial fossa is very rare. Primary meningeal melanocytoma is benign, it may behave aggressively. Complete surgical resection is curative for most cases, but recurrences have also been seen. Radiation therapy is significant to prevent relapse of the tumor, especially in cases of incomplete surgical resection.
