title: Primary nasal amelanotic melanoma: MR appearance.
abstract: The appearance on magnetic resonance (MR) images of a primary amelanotic malignant melanoma of the nasopharynx is reported. The factors affecting the MR appearance of melanomas of the head and neck are reviewed. The case is compared with a previously reported case of primary nasopharyngeal melanotic melanoma, and the importance of considering the tumor in all nasopharyngeal neoplasms is emphasized.
