Bochdalek's flower basket

Last revised by Rohit Sharma on 24 Mar 2025

Bochdalek's flower basket is the eponymous name for the incidental normal variant finding of protrusion of the choroid plexus through the foramina of Luschka.

This is a relatively common finding, with calcified Bochdalek's flower basket found in 38% of patients above the age of 51 years in one study using CT 4.

The finding is named after Vincent Alexander Bochdalek (1801-1883), the Czech anatomist who is most recognized for characterizing what is now known as the Bochdalek hernia 3.

It is an important normal variant to recognize as the presence of protruding calcified choroid tissue in the fourth ventricle can be confused with subarachnoid hemorrhage 2 or a cerebellopontine angle mass.
