Objective: Presentation of a case of cervical hibernoma.
Methods: Case report and review literature.
Subject: A 16-year-old woman with a right posterior triangle neck mass.
Results: Hibernoma is a rare, benign tumour of brown fat. The cervical area is an unusual localization. The presented case posed difficulties in the differential diagnosis of cervical masses, particularly with other hypervascular lesions such as sarcomatous tumours. A US-guided core biopsy was decisive in the identification of hibernoma. No meaningful bleeding or other complications biopsy related have been noticed.
Conclusion: Image-guided core biopsy is an indispensable tool to obtain an accurate preoperative diagnosis of cervical hibernoma.
