“…In our case, as in the case reported by Kim and Lee, 18F-FDG-PET/CT was able to depict this fatty tumor [6]. In our patient, the 18F-FDG-PET/CT scan resulted to be useful due to the whole-body coverage and incidentally identified the hibernoma, as a highly metabolic lesion.…”

Hibernoma is a benign tumor arising from brown fat tissue. Conventional imaging techniques are not able to differentiate it from other benign lesions or malignant fatty tumors. We report the case of a 73-year-old patient who underwent a thorax computed tomography (CT) and was then referred to our department for metabolic assessment of a solitary lung nodule. An F18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) scan was performed and demonstrated, in addition, a highly metabolic fat-containing lesion mimicking a malignant fatty tumor in the left great pectoralis muscle. The lesion was excised and resulted to be a hibernoma. This case shows that hibernoma can appear as a malignant-like lesion on 18F-FDG-PET/CT scan as per other imaging techniques, and the grade of FDG uptake does not accurately reflect malignancy in this fat-containing tumor. However, 18F-FDG-PET/CT with its whole-body scanning capability may represent a useful imaging tool in identifying, in the course of an imaging study for oncological evaluation, additional incidental findings such as benign fat-containing lesions that may require a surgical approach.

“…1,[65][66][67] Although metabolic measures may be useful to differentiate between low-and high-grade tumors, particularly of the same histologic type, PET has a more limited ability to discriminate between benign tumors and low-grade malignant tumors, due to overlapping metabolic activity. 64,68 It should also be noted that several benign MSK tumors may have striking FDG activity, such as giant cell tumor of bone, 69 tenosynovial giant cell tumor, 70 and hibernoma, 71 whereas malignant lesions may present with negligible uptake, such as myxoid liposarcoma 68 and low-grade chondrosarcoma. 72…”

The role of quantitative magnetic resonance imaging (MRI) and positron emission tomography/computed tomography (PET/CT) techniques continues to grow and evolve in the evaluation of musculoskeletal tumors. In this review we discuss the MRI quantitative techniques of volumetric measurement, chemical shift imaging, diffusion-weighted imaging, elastography, spectroscopy, and dynamic contrast enhancement. We also review quantitative PET techniques in the evaluation of musculoskeletal tumors, as well as virtual surgical planning and three-dimensional printing.

“…It is more vascular than normal lipomas and, because it is metabolically active, will demonstrate intense uptake on positron emission tomography. 19 Lipoblastoma is a rare benign lipomatous tumor seen in children; it contains immature fat cells (lipoblasts) and is thought to later evolve into lipoma. 20 Although not a true variant, some intramuscular lipomas will be infiltrated by traversing muscle fibers, giving a heterogeneous appearance that in some cases can be confused with welldifferentiated liposarcoma.…”
