Contrast enhancement of cranial lesions in computed tomography
tmt medium was evaluated in B series oi 41 patients

Diagnostic criteris are elalwrated. The study shows that small cerebrllo. pontine angle totnom coo be detected by use of CT machines of the newer generation, which perform scanti@ witt thin and overlopping slices. Author’s
