Abstract
An intraosseous lipoma is a rare histologic variant of lipoma, accounting for only 0.1% of all primary bone tumors. This may not be the actual incidence because most of these lesions are frequently asymptomatic, but imaging modalities, such as computed tomography or magnetic resonance imaging (MRI) seem to have increased the detection rate. Lipoma occasionally undergoes osseous metaplasia and becomes an osseous lipoma. Although there are numerous papers discussing intraosseous lipoma and some authors have tried to differentiate lipomas from osseous lipomas, there is still a great deal of confusion with regard to characteristic radiologic features and the use of terms. Use of the mDixon sequence in MRI could be an effective, noninvasive method of lesion detection and differential diagnosis. Texture analysis is a useful technique for capturing intratumoral characteristics. We report what is possibly the first use of the mDixon MRI sequence in the measurement of tumoral texture in a case of the extremely rare inferior nasal turbinate intraosseous lipoma in a 58-year-old female. We conclude that mDixon and texture analysis are helpful methods for differentiating intraosseous lipomas from other masses and confirming the benign characteristics of lipoma. Our review of head and neck intraosseous lipoma could be of particular interest to head and neck surgeons and dental clinicians.
