RESUMEN
A large vestibular aqueduct, an isolated anomaly of temporal bone, is relatively rare and its association with sensorinerual hearing loss in childhood is known as the enlarged vestibular aqueduct syndrome. Using MRI, we found enlarged endolymphatic ducts and sacs in four ears of our two patients. Signal intensity of enlarged endolymphatic sac that is detected higher than that of CSF in Fluid Attenuated Inversion Recovery (FLAIR) image may indicate poor prognisis with respect to bone conduction threshold in pure tone audiogram.

Nevus lipomatosus cutaneous superficialis is a very rare disorder characterized by nevoid fatty growth in the dermis. It usually arises in the pelvic girdle, so is unfamiliar to most otolaryngologists. A case of a 72-year-old male with nevus lipomatosus cutaneous superficialis in the nasal cavity is presented with a brief review of the disease.
