title: Computerized tomography findings in posterior fossa lesions.
abstract: In 190 of 7000 brain CT studies performed between April 1978 and September 1984, abnormalities of the posterior fossa were found. Of these, 51.5% were primary tumors, 15.3% metastases, 12.1% vascular lesions and 5.8% congenital or developmental lesions. Frequencies, age and sex distribution and radiologic characteristics of the various posterior fossa pathologies are reviewed and discussed.
