Imaging of Kallman Syndrome
It is easiest to appreciate the anatomical anomalies present in Kallman syndrome by comparing it to a normal patient.
The normal anatomy of the region consists of the olfactory bulbs (blue arrows) located in the olfactory grooves of the anterior cranial fossa.
The inferior surface of the frontal lobes usually consists gyrus rectus (aka straight gyrus) (R) separated from the medial orbital gyrus (M) by the olfactory sulcus (yellow arrow). These are absent in Kallman syndrome.
