Intracranial intradural epidermoids and dermoids. Surgical results of 38 cases

Abstract

This report covers 38 Cases of intradural dermoids (4 cases) and epidermoids (34 cases). In most cases the clinical course extended over several years. At the time of admission to the clinic only 9 patients had purely local symptoms; symptoms from adjacent areas were present in 15 cases and elevated intracranial pressure in 13. Of the 35 operated patients, 16 were able to work again, and 7 died after the operation. Best results are achieved in cases involving young patients, in cases where the tumor is situated in the cerebral hemisphere, and in cases where the tumor can be totally removed. In recent years advances in diagnostic, surgical and anaesthetic techniques have lowered the lethality rate. Computed tomography is especially useful for an early diagnosis.
