Melanotic neuroectodermal tumor of infancy(MNTI)is a rare, pigmented neoplasm of neural crest origin, and it often follows a benign course. We report a case of a 3-month-old girl with MNTI. On MRI, MNTI shows less conspicuous high signal on T1-weighted images compared to other melanin-producing tumors, and there are some findings that may suggest malignancy. It is important to consider these issues in diagnostic imaging and to list them as differential diagnoses for maxillary masses in infants and young children.
