Osteoma is the most common benign tumor of the nose and paranasal sinuses, and the frontal sinus is its most frequent location. This tumor may be discovered incidentally on radiographs or may enlarge to produce symptoms and, rarely, complications referable to its location near the orbit and anterior cranial vault.

Frontal sinus osteoma surgery.

No report has mentioned osteomas 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 ¹⁾.
