pacchionian bodies

Smaller granulations are called villi, large calcified ones are referred to as pacchionian bodies.

Near the groove are several depressions, best marked in the skulls of old persons, for the arachnoid granulations (Pacchionian bodies).

Occasionally, they are referred to by their old name: Pacchioni's granulations or pacchionian bodies, named after Italian anatomist Antonio Pacchioni.

Most of the cerebral veins from the outer surface of the hemisphere open into these lacunæ, and numerous arachnoid granulations (Pacchionian bodies) project into them from below.

Paccioni's granulations (or pacchionian bodies), where the arachnoid layer protrudes through the dura, are named for him (although they are now generally known as arachnoid granulations).
