title: [Computer tomographic detection of an intraspinal arachnoid cyst].
abstract: Clarification of the subjective complaints caused by meningeal malformations represented by an arachnoidal cyst in the sacral region was achieved for the first time by analysing an arachnoidal cyst which had been determined by myelography, computed tomography, biopsy and histological examination. Principles of mechanics and dynamics play an important part. The pattern of complaints is mainly due to the communication between the cyst and the CSF space, as well as a valve mechanism with filling of the cyst. Surgical reduction or removal of the cyst, and elimination of the connection with the CSF, produced freedom from complaints.
