The majority of melanotic neoplasms of central nervous system(CNS) are metastatic
in origin and rarely a primary CNS melanomas, and are usually histologically and
clinically malignant in nature. The meningeal melanocytomas are benign, primary
melanotic neoplasm and are less common than primary CNS melanoma. They usually
present in early adult and have a characteristic appearance in light and electron
microscope. A 42-year-old male is presented with pain on the neck and suboccipital
region which was worse with flexion and Valsalva's maneuver. MRI revealed
homogenous high signal intensity on the T1 weighted image and low
signal intensity on the T2 weighted image. At operation, the tumor was
well composed of spindled and epithelioid cells with often prominent nucleoli, without
evidence of mitosis and necrosis.
