Abstract
Pneumoventricle and liquoric fistula are possible complications of traumatic brain
injury (TBI), the main cause of morbimortality related to trauma in Brazil. Liquoric
fistulae are more common after direct trauma with skull base fractures. However, pneumoventricle
is rare and occurs due to excessive cerebrospinal fluid (CSF) drainage in the presence
of a poorly compliant ventricle system, resulting in the influx of air to its interior.
The pathophysiology of tension pneumoventricle remains uncertain. However, the traumatic
cause is certain and multiple bone fractures of the face and liquoric fistula may
contribute to the process. If symptomatic, the tension pneumoventricle can cause rapid
clinical deterioration. The authors aim to report a rare case of post-TBI tension
pneumoventricle with complete resolution and without signs of recurrence of the liquoric
fistula after surgical treatment.
