Background:
The natural history of colloid cysts is imperfectly understood, and controversies remain in defining broad management strategies for incidental colloid cysts. The gradual asymptomatic regression of a colloid cyst has not been reported.
Case Description:
We present a unique case demonstrating the clinically silent, gradual regression of a colloid cyst over many years.
Conclusions:
Gradual regression of a colloid cyst is possible. The philosophical and practical implications of this case on the neurosurgeon's approach to managing patients with colloid cysts are discussed.
