title: Reversible contrast-enhanced lesions of basal ganglia and brain stem on computed tomography.
abstract: Two cases of reversible CT contrast-enhanced lesions simulating brain neoplasms are described. Following steroid therapy and shunting procedure normalization of the clinical signs and of the CT scans occurred. The role of a vasculomyelinopathy as a possible pathogenetic factor of these lesions is stressed.
