Abstract
Most common non-tumorous lesion of the pineal gland is a pineal cyst. Prevalence of pineal cyst in general population is 0.7-1.5%.
Most PCs are asymptomatic, and their diagnosis is rather incidental. Surgical treatment in patients with non-specific symptoms is controversial.
However, literature suggests improvement in majority of patients. Other non-tumorous lesion of the pineal gland are calcifications, apoplexy and arteriovenous malformation.
