Cerebellar tonsils

Last revised by Assoc Prof Craig Hacking on 03 Sep 2020

The cerebellar tonsils are ovoid structures on the inferomedial surface of each cerebellar hemisphere. They are attached to the underlying cerebellum by the tonsillar peduncle 1-4.

  • medial: uvula of the vermis
  • superior: flocculonodular lobe
  • anterior: posterior surface of the medulla and the cerebellomedullary fissure
  • posteroinferior: cisterna magna

Arterial blood supply to the cerebellar tonsils is through an anastomosis of branches from the anterior inferior cerebellar and posterior inferior cerebellar arteries 3,4.
