[A case report on congenital anosmia].

We report 2 cases of congenital anosmia, in a 13-year-old girl and the other in a 10-year-old boy. They reported having no concept of "smell". The girl has no complications but the boy has congenital microphthalmia and is completely blind. They showed scale-out results on both T & T olfactometry and intravenous Alinamin test. Brain MRI detected hypoplasia or lack of the olfactory bulbs, tracts, and olfactory sulci in the frontal lobe of the brain in both patients. Neither had endocrinal dysfunction. In the boy, we biopsied the nasal mucosa in the olfactory cleft and found it had no olfactory epithelial cells at all. We found MRI to be the most useful imaging for diagnosing congenital olfactory disturbance.
