[Meniscus ganglia. Diagnosis and differential diagnosis]

3% of isolated meniscectomies were performed on patients with cysts of the meniscus. The etiology is not yet fully elucidated. The problems in clinical and radiological diagnosis are discussed using the examples of two operatively verified cases. In computerized tomography the density values of these lesions range from 20 to 35 Hounsfield units thus allowing specific diagnosis. Localization and extent of the cyst can be shown exactly by computerized tomography.
