title: Computerized tomography in a calcified postoperative extradural cyst.
abstract: Extradural cysts resulting from dural/arachnoidal tears are unusual postoperative complications. A case of a calcified cyst is reported, emphasising its mechanism of formation, clinical significance and radiographic features. It is quite surprising today that the question should still arise as to whether computerized tomography is able to enrich the process of diagnosis, and if so in what circumstances.
