FOREARM-WRIST HIBERNOMA: A RARE BENIGN TUMOUR OF BROWN FATTY TISSUE
Abstract
Abstract
Objective: To reveal the magnetic resonance imaging findings of hibernoma which is rarely seen benign brown fat tissue tumor, usually seen in adults, that develops from fetal fat tissue residues.
Case: 14-year-old female who noticed for the last 1 month immobilized soft tissue mass in her left wrist admitted to the orthopedic polyclinic. There was no pain. There was no circulatory problem or neurological deficit in this extremity. After that patient was referred radiology department. Magnetic resonance imaging was performed. On postcontrast T1 weighted fat-suppressed sequence, lesion showed homogeneous contrast enhancement (unlike lipoma) and there was a small hypointense area on central part of the lesion which demonstrates fat tissue. Patient was operated. Histopathological diagnosis was hibernoma.
Conclusion: Hibernoma should be considered in patients with immobilized soft tissue mass without significant symptom on the forearm-wrist.
