ROLE OF MRI IN THE DIAGNOSIS OF OTITIC HYDROCEPHALUS

The pathogenesis of otitic hydrocephalus still remains doubtful. Magne tic resonance imaging (MRI) demonstrated sigmoid and transverse sinus thrombosis in two consecutive patients. The role of MRI in the diagnos is and pathogenesis of this complication, together with literature fin dings, is discussed. Until now lumbar puncture, which is a minimally i nvasive technique, was the only diagnostic measure. MRI, however, can be used to establish the diagnosis of otitic hydrocephalus by showing the thrombosis in the sigmoid and transverse sinus.
