18F-FDG PET/CT Demonstrating Crossed Cerebellar Diaschisis Due to Germ Cell Tumor of the Basal Ganglia: A Case Report

Clin Nucl Med. 2022 Jun 1;47(6):e455-e456. doi: 10.1097/RLU.0000000000004175. Epub 2022 Apr 4.

Abstract

Germ cell tumors of the basal ganglia are rare neoplasms that usually present with hemiparesis or other neurological symptoms. MR and PET/CT with different tracers have demonstrated their usefulness for the correct assessment of disease. Crossed cerebellar diaschisis refers to a depression in metabolism of a cerebellar hemisphere as a result of contralateral supratentorial lesions. We present a case in which MR and PET/CT were crucial for the assessment of left basal ganglia germ cell tumors with the presence of crossed cerebellar diaschisis.
