Bochdalek's flower basket is the eponymous name for the incidental finding of protrusion of the choroid plexus through the foramina of Luschka. This is a relatively common finding.

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  or a cerebellopontine angle mass.

History and etymology

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 .
