Evaluation of Posterior Fossa Lesions by Computer Assisted Tomography (CAT)

Authors: THOMAS LOTT MD, TAHER EL GAMMAL MD, ILDEMARO VOLCAN MD

Abstract

ABSTRACTValuable neuroradiologic information can be obtained with routine examination of the posterior fossa by computer assisted tomography (CAT). The diagnosis can be difficult in the posterior fossa due to the relatively small size of the compartment and its proximities to large bony masses and air in the mastoid cells. However, many lesions can be accurately diagnosed when close attention is given to anatomic detail and the frequent use of contrast enhancement. We introduced a new CAT classification of posterior fossa neoplasms.
