A full-term, 7-month-old male infant presented to an outpatient pediatric otolaryngology clinic with a firm, irregularly shaped posterior neck mass. He had been diagnosed prenatally with cerebellar hypoplasia, so a magnetic resonance imaging study of the brain was performed at 1 month of age. This study demonstrated an incidental solid, homogenous mass in the subcutaneous fat of the right occiput with irregular borders and infiltration into the paraspinal musculature (Figure, A). On examination, the upper posterior neck mass was deep to palpation without overlying skin changes. The patient had no discomfort, and neck movement was not restricted.
