- Septocallosal interface
The callososeptal interface is located on the inferior surface of the corpus callosum, where the septum pellucidum abuts it.
It came to radiological attention when T2 hyperintense lesions affecting this region were believed to be specific for multiple sclerosis. This has, as is usually the case, been shown not to be quite as cut and dry, with ischemic lesions also potentially affecting this region 1.
Practical points
Involvement of the callososeptal interface may help in distinguishing multiple sclerosis from Susac syndrome as the latter predominantly involves the central part of the corpus callosum rather than the interface 2.
