Deltoid Hibernoma of Atypical Presentation: Clinical Case
https://doi.org/10.58531/ijmhr/1/1/3
INTRODUCTION. Hibernoma, a benign tumor of brown fat, first described as “pseudolipoma” by Merkel (1906), was named “hibernoma” by Gery (1914) due to its morphological resemblance to brown fat observed in hibernating animals. They are uncommon, accounting for<2% of benign lipomatous tumors and 1% of all adipocytic tumors. CLINICAL CASE. Soft tumor in the right anterior deltoid region, 8x10 cm, ovoid in shape, does not beat or fluctuate, nor adheres to deep planes, painful movement and becomes more evident with flexion-abduction-external rotation of the right upper limb. Abscessed Cystic Lesion, covered by fibrous and calcified wall. Encapsulated and Sclerosed Abscess Wall. Negative for Malignancy. The patient evolved satisfactorily. The stitches were removed 14 days later and he returned to his usual activities 2 months after the operation. DISCUSSION. In a case of hibernoma, radiographs do not show calcifications or bone erosion. Ultrasonography of a hibernoma reveals a well-circumscribed, uniformly hyperechogenic mass. On computed tomography, the lesion is usually lobulated, septate, and well-defined, with fat density and variable contrast enhancement. On T1-weighted MRIs, Hibernoma appear hypo intense with respect to fat, whereas on T2-weighted images they are usually is intense with respect to subcutaneous fat. Radiological and histological differential diagnoses of Hibernoma include other benign soft tissue tumors such as lipomas, rhabdomyomas, neurofibromas, fibromas, hemangiomas, as well as malignant tumors including well-differentiated liposarcomas or metastatic carcinoma.
