[[Osteoma]] is the most common [[benign tumor]] of the [[nose]] and [[paranasal sinus]]es, and the [[frontal sinus]] is its most frequent location. This tumor may be discovered incidentally on [[radiograph]]s or may enlarge to produce [[symptom]]s and, rarely, [[complication]]s referable to its location near the [[orbit]] and anterior [[cranial vault]].

===== Case reports =====

No [[report]] has mentioned [[osteoma]]s in blood supply on [[MRI]]. A 57-year-old male patient presented with a prolonged declined activity and a gigantic [[bone tumor]] that originated from the [[frontal sinus]], which markedly compressed the bilateral [[frontal lobe]]. MRI revealed a slightly enhanced front basal part of the tumor by [[gadolinium]], with blood supply from the [[ethmoidal artery]]. The patient underwent surgery, and the diagnosis of [[osteoma]] was made based on histological findings. Watanabe et al. reported a case of giant osteoma originating from the [[frontal sinus]] with unusual blood supply on 4-dimensional [[MR angiography]]
