Calvarial hyperostotic syndrome(CHS)
Also known as: Calvarial hyperostosis · Schädelhyperostose · Calvarium-Hyperostose-Syndrom · Cortical hyperostosis of the skull
Overview
What it is
Calvarial hyperostotic syndrome is a rare bone disorder affecting the skeletal system of young dogs, specifically causing abnormal, non-cancerous thickening of the skull roof, known as the calvarium. This bone overgrowth occurs during the rapid growth phase, leading to localized inflammation and pressure on surrounding tissues.
How it presents
Symptoms typically appear in young dogs between 5 and 10 months of age, manifesting as visible, firm bumps on the top of the head. Owners may also notice extreme sensitivity to touch in the affected area, fever, and general lethargy.
Treatment
The condition is treatable and usually resolves on its own once the dog's growth phase is complete. Treatment is temporary, focusing on pain management and anti-inflammatory medications, with typical costs ranging from 500 to 2000 EUR.
