Teaching Case: Crossed Cerebellar Diaschisis with Atrophy

This Eurorad teaching case demonstrates crossed cerebellar diaschisis (CCD) with atrophy, a phenomenon where a supratentorial lesion causes decreased metabolism and perfusion in the contralateral cerebellum, visible on MRI and PET.

• Single case from Eurorad illustrating imaging hallmark of CCD.
• Cerebellar atrophy indicates chronicity of the supratentorial insult.
• Important for radiologists to recognize to avoid misdiagnosis of primary cerebellar pathology.
