Hypergranulation and crust formation after cranial neurosurgery is rare. We report three patients with an uncommon form of hypergranulation with extensive crust formation after cranial neurosurgery, associated with a St. Aureus infection of the scalp, and propose that this is a form of pyogenic dermatitis, as is commonly seen among domestic animals with a coat of fur. It can be treated conservatively. We propose a treatment algorithm.
