A 9-month-old female presented to the ENT clinic for a rapidly enlarging left neck mass over 3 months. The mass extends from the supraclavicular region to the occiput, involving the entire left neck. The patient exhibited weakness of the left upper extremity and no other symptoms. Magnetic resonance imaging (MRI) showed a well encapsulated, high-signal intensity mass with low-signal intensity septa on T1 sequence (Figure 1). On fat suppressed sequence, the corresponding mass demonstrated homogenous low signal intensity (Figure 2). Histologic analysis identified lobules of fat with occasional collections of lipoblasts and areas of myxoid degeneration. The mass was resected with no subsequent complications.Lipoblastoma is a rare benign neoplasm of fetal white fat cells presenting in different maturation stages within a mucopolysaccharide dominant myxoid matrix. 1 It typically occurs in children under the age of 3 with predilection for the extremities and can rarely occur at other locations such as the head and neck, as seen in our patient. Males are 3 times more frequently affected than females. 2,3 Patients typically present with a nontender enlarging mass of the soft tissue. 3 Symptoms can occur
