Mediastinal hibernoma

Mediastinal hibernoma: a case report.

Hibernomas are rare benign tumours that arise most often in adults from the remnants of fetal brown adipose tissue. They usually affect muscle and subcutaneous tissue and are asymptomatic and slow growing. The distribution of this tumour follows the sites of persistence of brown fat. Out of more then 100 cases described in the word literature only three hybernomas were mediastinal. A recent cli...

Mediastinal Hibernoma: A Rare Case with Radiologic-Pathologic Correlation

Hibernomas, especially located in the mediastinum, are extremely rare benign tumors, which are important to consider in the differential diagnosis of a heterogeneously enhancing mass with areas of fat attenuation on imaging of an often incidentally discovered mass. Other common possibilities in the differential include malignant tumors, such as liposarcoma, hence histopathology is usually requi...

Intrathoracic hibernoma.

loculated fat cells morphologically similar to the hibernating gland tissues found in animals was first recognized 95 years ago. It was subsequently termed “hibernoma.” In 1966, 38 cases had been recorded, 4 of which were intrathoracic. Thirty years later, approximately 100 cases had been reported, of which only 7 were intrathoracic. A recent review of the English literature reveals 13 intratho...

Cervical hibernoma and lipoblastomatosis

Lipoblastoma and lipoblastomatosis are rare benign soft-tissue tumoral lesions resembling fetal adipose tissue. A total of 16 cases of lipoblastoma of the neck were reported in the literature, and only 3 were described in the posterior side of the neck. Hibernoma is a rare benign adipose tumor composed of brown fat cells and only about ten cases occurring in the cervical area have been reported...
