Subcutaneous Fat Necrosis in a Newborn after Brief Therapeutic Hypothermia: Ultrasonographic Examination

Abstract

A 7-day-old infant developed erythematous indurated plaques on the back, left shoulder, and arm a few days after therapeutic hypothermia. Ultrasonographic study along with Doppler blood flow analysis of lesional skin areas revealed flogistic fat involvement and calcifications. On the basis of clinical appearance, patient history, and ultrasonographic study, a diagnosis of subcutaneous fat necrosis of the newborn was established.
