The problems presented in the surgical treatment of cerebellar abscess are far from solution; many of the statements current are incorrect, while the operative mortality is still very high.
In order to determine the exact situation of the intradural suppuration and other pathologic facts which may have a surgical application, I have, with the assistance of Dr. Robbins, examined all the recorded postmortem reports of patients dying from cerebellar abscesses.
