Abstract

Two cases of subdural tension pneumocephalus were introduced after posterior fossa surgery in the sitting position. The possible mechanism for entry of air into the subdural space is explained as the fluid pours out air bubbles to the top of the container. All of two cases manifested generalized seizure at recovery room and were diagnosed with plain skull series and computed tomogram. Subdural air evacuated patient fail to recover as expected, following posterior fossa surgery in sitting position.
