Epidermoid tumour (tumor perlee, cholesteatoma) of the fourth ventricle: case report and review of literature

“…To the best of my knowledge, no one has reported this pattern in an air study of an epidermoid in the third ventricle. Patriquin et al (1969), Tytus andPennybacker (1956), andSheldon et al (1953) have reported that the pneumoencephalographic appearance of the epidermoid tumour in the fourth ventricle is similar to that reported in the lateral ventricles.…”

The Relative Merits of Encephalography and Ventriculography for the Investigation of Intracranial Tumours

“…In recent years several cases and series of cases have been reported where this modern technique has been used also in posterior fossa tumours and in cases where the intracranial pressure is raised (Lindgren, 1951;Falk, 1953;Ruggiero, David, and Talairach, 1955;David, Ruggiero, and Talairach, 1954;Ruggiero, 1956;Robertson, 1941Robertson, , 1946Dressler and Albrecht, 1956;Sheldon, Wickbom, and Pennybacker, 1953;Wickbom and Sheldon, 1953) among many others. Falk, in his series of 195 tumour cases (including 37 tumours in the posterior fossa) examined by encephalography, reported no ventricular filling in 24 cases (eight supraand 16 infratentorial tumours).…”
