Nasal glioma is a rare congenital midline malformation composed of heterotopic masses of neuroglial tissue. We report a case of fetal nasal glioma diagnosed by sonography at 22 weeks' gestation as a vascular hypoechoic mass located on the left nasal bone. Fetal MRI excluded an underlying bone defect. At birth, the lesion appeared as a reddish mass. Post natal imaging confirmed the vascularisation within the lesion with an arterial low-flow velocity and a high-resistance spectrum, consistent with a glioma. The child underwent surgery at 5 months and final diagnosis was made on pathological examination. Therefore, a vascular lesion and a clinical aspect mimicking a haemangioma should not be considered sufficient to reach the final diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
