What is a septum cavum pellucidum?
My son has bi-lateral retinoblastoma and during a routine MRI of the brain/orbits a "septum cavum pelludicum" was noted. Please tell me what this is.
Cavum septum pellucidum is an anatomic variant in which a brain structure, the septum pellucidum, has a division within it. It is fairly commonly seen on MRI scans and is generally not of any clinical significance.
