A Rare Case of Huge Intraosseous Vascular Malformation of the Mandible: a Case Report

Abstract

Unlike malignant tumors, vascular malformations are regarded as hamartomas or congenital malformations of vascular tissue. Vascular malformations are more uncommon in bones than in soft tissue, with the mandible accounting for 0.5–1.0% of all intraosseous malignancies, highlighting the rarity of mandibular vascular anomalies. We present a case of a huge bony swelling present in the mandible of a 21-year-old man which showed a multilocular appearance on the MRI and CBCT. The rarity of this case lies in the huge intraosseous extent of the lesion present for 10 years which slowly increased in its size to the current extent. Cone Beam Computed tomography (CBCT), magnetic resonance imaging (MRI), and Fine Needle Aspiration (FNA) were made for diagnostic purposes. The FNA when performed gave a passively filling blood aspirate. On the basis of available investigations, a diagnosis of the lesion being a vascular malformation was made.
