title: A Rare Case of Retropharyngeal Hibernoma.
abstract: 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.
