Abstract
Hibernomas are uncommon benign soft-tissue tumors which are composed of brown fat.
They are usually seen in adults in the fourth and fifth decades and the common locations
are thigh, shoulder, and back. Only few cases in the posterior neck region have been
reported in literature. Hibernoma is very uncommon in the pediatric age group and
those in the neck region are extremely rare. We present a hibernoma presenting as
a swelling on the posterior aspect of base of the neck in a 5-month-old male infant.
Considering the rare occurrence in the pediatric age group and difficulty in diagnosis,
the clinical features, radiological features, pathological characteristics, differential
diagnosis, and management of this rare tumor of childhood are discussed herewith.
