Unusual “Dumbbell”-Shaped Hibernoma

We present the case of 33-year-old woman who presented with a palpable lump over superior aspect of her thigh associated with pain. Magnetic resonance imaging examination reported a “dumbbell”-shaped soft tissue tumor involving the right side of the pelvis and adductor compartment passing through the obturator foramen into the adductor compartment infiltrating the hip joint. Clinical and imaging features initially suggested liposarcoma, but ultrasound-guided biopsy and final surgical resection yielded the diagnosis of hibernoma. This rare soft tissue tumor can imitate malignancy, but magnetic resonance imaging and possibly guided biopsy are essential for preoperative planning as surgical resection remains the best management pathway.
