What is the importance of radiology in obstructive sleep apnea?

Lipomas are rare, and they rarely arise in deep soft tissue. Only few cases associated with obstructive sleep apnea (OSA) have been reported. Because of radiologic examinations (computed tomography and magnetic resonance imaging) in a case with OSA, a rarely observed large lipoma was encountered in the retropharyngeal region. In the case that was followed, the apnea-hypopnea index was measured. The radiologic examination of the upper airway of the case with OSA symptoms was presented.
