A case of fronto-basal traumatism with isolated fracture of the left sphenoidal sinus is reported. Meningitis occurred 5, 8 and 11 years, respectively, after injury. Cerebrospinal fluid cranio-nasal fistula was observed at the first time 8 years after injury and remained intermitent in the last 6 years. The surgical technic was accomplished according to the procedure devised by Dietz and consisted of plastics of the anterior floor of the skull accompanied by galeaperiosteal junction taken out from the scalp.
A case of cryptococcal meningoencephalitis occurrying in a 26-year-old white man disclosing clinical as well radiological features of a expanding process localized in the right cerebral hemisphere is reported. A definitive diagnosis was established through histopathologic examination following right fronto-temporo-parietal exploratory and decompressive craniotomy.
