Nasal dermoid


MR – Axial T1, T2, diffusion-weighted and apparent diffusion map images demonstrate a small oval lesion present within the soft tissues just anterior to the nasal bridge with homogeneous T1 and T2 signal hyperintensity and restricted diffusion.


Nasal dermoids, as well as nasal dermal sinuses and epidermoid cysts, develop secondary to anomalous closure of the anterior neuropore during development and can occur at multiple locations from the glabella to the columella. These lesions may be associated with external skin ostia or deep sinus tracts, which may extend intracranially. CT attenuation and MR signal intensity varies depending on content. Dermoid and epidermoid cysts are firm, nonpulsatile lesions that do not transilluminate and do not change in size with crying or with compression of the jugular veins.
