Dermoid tumor with involvement of the frontal lobes.
Intraparenchymal location of a dermoid tumor is extremely rare, and there are only four reports in the literature. This article presents a patient with a dermoid tumor with trilobulated components; an extra-axial component in the basal frontal/ethmoidal region, and two intra-axial components located in each frontal lobe. In addition, two small fat-density lesions anterior to the component in the left frontal lobe were present, probably due to partial intraparenchymal rupture of the tumor. The pathogenesis of intra-axial locations is still controversial, and this article proposes that in at least some cases intraparenchymal rupture of dermoids can cause intra-axial dermoids.
