“…Bone infarcts are source of diagnostic confusion, as it contains fat and often have a low signal intensity rim while calcaneal intraosseous lipoma is an expansile lesion that remodels cancellous and cortical bone, which is not a feature of bone infarction [2]. Intraosseous lipoma is often confused histologically or radiologically with fibrous dysplasia, enchondroma, osteoblastoma, chondrosarcoma, bone cyst, and bone infarct [2,3,5,6]. The lesion may appear as purely lytic with ill-defined margins, mimicking osteomyelitis, metastasis, or eosinophilic granuloma [7].…”

Calcaneal Intraosseous lipoma is a very rare lesion usually benign tumor, which constitutes not more than 2% of bone tumors. On plain radiographs, an intraosseous lipoma is usually seen as benign-appearing osteolytic bone lesion with well-defined margins and calcified/ossified dense matrix. Plain radiographs alone cannot establish the diagnosis of intraosseous lipoma as it imitates several other benign and malignant bone lesions. Intraosseous lipoma contains calcified necrotic fat with mature adipose tissue and characteristically induces expansion/remodeling of the affected bone.

Intraosseous lipoma of the third lumbar spine: a case report

IntroductionIntraosseous lipoma is a benign bone tumor, and the tumor occurs more frequently in the lower extremities. We present a very rare case of intraosseous lipoma occurring in the lumbar vertebral arch and spinous process.Case presentationA 54-year-old Japanese man presented with a three-month history of lumbar pain. Magnetic resonance imaging of the L3 vertebral arch and spinous process revealed high intensity on T1- and T2-weighted imaging, and it was suppressed on fat-suppression imaging and no enhancement showed on gadolinium contrast-enhanced imaging. Computed tomography imaging revealed an osteolytic change accompanied by marginal osteosclerosis in his third lumbar vertebral arch and spinous process, as well as a thinned and bulging bone cortex. An analgesic had been administered prior to his visit, but low back pain had persisted, so we performed curettage and filled the defect with hydroxyapatite bone. His low back pain was improved immediately after surgery, and no recurrence of tumor has been observed on computed tomography imaging as of three years postoperatively.ConclusionsSymptomatic intraosseous lipoma of spine is very rare, but the patient may be surgically well-treated by curettage and reconstruction of the benign tumor.

Lipomas are the most common form of benign mesenchymal tumors and are composed of mature adipocytes. They can occur anywhere in the body where fat is found and thus, called as the ‘universal tumor’ or the ‘ubiquitous tumor’. Intraosseous lipomas (IOL) are among the rarest (0.1%) of primary bone tumors and are very rarely seen in head and neck bones. They have been subdivided based on the site of origin within bone, into intramedullary and intracortical. Of the two, few cases of intramedullary lipoma have been reported intraorally and none of the latter. Intraosseous lipomas are usually asymptomatic and are detected incidentally on radiographs taken for other complaints. Here, we report a case of intraosseous lipoma in the mandible presenting as a large swelling.
