CALVARIAL THINNING IN LOW-GRADE INTRACEREBRAL GLIOMAS PRESENTING WITH EPILEPSY

Intracranial gliomas can erode or thin the skull. These changes are detectable on conventional radiographs but they appear to be rare. Only a few examples of the appearances on computed tomography (CT) are recorded in the literature. This paper describes the CT appearances of 11 cases. All of the patients presented with epilepsy. In most the tumours were small and indolent. Some went undetected or misdiagnosed for several years because of a lack of familiarity with the appearances.
