Congenital cholesteatoma of the mastoid bone is a rare, non-epithelial cyst or tumor that exists in the mastoid bone at birth. Computed tomography (CT) and magnetic resonance imaging (MRI) are useful in evaluating congenital cholesteatoma and can help determine the extent of involvement of the mastoid bone and surrounding structures. Surgical removal is usually required to prevent complications like bone erosion and hearing loss.
