[MR tomography of Kallmann's syndrome].

MR tomography is the only imaging method that can demonstrate atrophy of the olfactory lobe of the brain in olfacto-genital dysplasia (Kallmann's syndrome). The MRT findings in five patients with Kallmann's syndrome are described. The MRT criterion for the presence of Kallmann's syndrome appears to be an interruption or total absence of the olfactory sulcus.
