RT Journal Article SR Electronic T1 Imaging Findings of a Hibernoma of the Neck JF American Journal of Neuroradiology JO Am. J. Neuroradiol.

Yousem YR 2006 UL http://www.ajnr.org/content/27/8/1658.abstract AB SUMMARY: Hibernoma is an uncommon benign fatty tumor that arises from the vestiges of fetal brown fat. We present a case report of a hibernoma of the neck in an asymptomatic 19-year-old girl and describe the important imaging findings. Computed tomography (CT) shows a well defined hypodense mass with septations. Magnetic resonance imaging (MRI) shows intermediate T1 and bright T2 signal of the mass and also demonstrates the characteristic marked contrast enhancement.
