Hibernoma is a slow growing, rare benign tumour, which
derived from brown adipose tissue. This tumour is usually
found in the area where foetal fat persists such as back,
axilla, retro peritoneum and thorax. Hibernoma rarely occurs
in the retro pharynx. We report a case of retropharyngeal
hibernoma in a 44-year-old male. He presented with
obstructive symptoms for six months and a retropharyngeal
mass upon examination. His CT scan findings showed a
mass in the prevertebral region from level of C2 until C5
causing narrowing of upper aero digestive tract.
Histopathological examination reported as hibernoma.
