Dear Sirs,

Melanocytoma, a benign tumor derived from the leptomeningeal melanocytes, involves the posterior cranial fossa in more than a half of the cases [ 1, 2, 3]. Melanocytoma has shown neurotologic findings mostly when involving the cerebellopontine angle (Table  1, Supplementary file). Since melanocytoma may show a malignant behavior, an early diagnosis is important [ 4]. Herein, we first describe a patient with melanocytoma involving the dorsal medulla and lower pons, which presented hemifacial spasm and recurrent attacks of paroxysmal vertigo and tinnitus mimicking vestibular paroxysmia.
