Cavum Septum Pellucidum in Pediatric Traumatic Brain Injury

A recent study investigated how the presence, size, and shape of the cavum_septum_pellucidum (CSP), a fluid-filled cavity in the brain, correlates to the diagnoses and severity of traumatic brain injury (TBI) in youths.

The study subjected 98 children with TBI and 34 children in a control group to neuroimaging by MRI; the imaging confirmed the presence of the CSP, assessed the quantitiative values of length and volume of the CSP, and assessed the qualitative values of an abnormally large CSP and rating of the CSP.

Children with TBI were observed via MRI to have larger and more severely graded CSP. Researchers also positively correlated the size of the CSP and the severity of the TBI. These results suggest the CSP should be considered along with other changes in the brain when diagnosing - and observing outcomes - in adolescents with TBI.
