Abstract:
Nasal angiomas are rare. We report a case showing osseous metaplasia and discuss pathogenesis hypotheses. A 41-year-old woman presented with a right lateronasal firm, immobile mass, and interfering with glass wearing. The computed tomography scan imaging was suggestive of chondroma while the magnetic resonance imaging showed on T1-weighted images nodule isosignal, on T2-weighted images hypersignal, and intense enhancement after contrast substance injection. The lesion was surgically resected. Histological examination revealed a 0.8 cm angioma with multifocal osseous metaplasia. The diagnosis of nasal angiomas with extensive osseous metaplasia is difficult requiring microscopic examination. Conservative surgery is the treatment of choice even at an early stage due to the limited effectiveness of embolization or drugs on the osseous component.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
