Meningeal melanocytoma in the left frontal region.

We report a rare case of meningeal melanocytoma in the left frontal region. A 45-year-old man complained of a headache. Magnetic resonance (MR) scanning showed characteristic patterns: a slightly high signal intensity mass in the left frontal region on the T1-weighted image and a low signal intensity on the T2-weighted image. The patient underwent gross total removal of the tumor. The postoperative course was uneventful. After two years, there was a small local recurrence. The histological finding of the tumor showed meningeal melanocytoma. To our knowledge, this is the second published report of a meningeal melanocytoma in the supratentorial region.
