“…The corpus callosum, and particularly the posterior corpus callosum, has been implicated by multiple studies as an important white matter tract for CUD. 3,5,[20][21][22][23][24][25] CUD deficits have been reported in moderate to severe TBI. 5,21 These deficits have been studied less in mTBI.…”

This study examined whether peripheral vision reaction time (PVRT) in patients with mild traumatic brain injury (mTBI) correlated with white matter abnormalities in centroaxial structures and impairments in neuropsychological testing. Within 24 h after mTBI, crossed reaction times (CRT), uncrossed reaction times (URT), and crossed-uncrossed difference (CUD) were measured in 23 patients using a laptop computer that displayed visual stimuli predominantly to either the left or the right visual field of the retina. The CUD is a surrogate marker of the interhemispheric transfer time (ITT). Within 7 days after the injury, patients received a diffusion tensor-MRI (DTI) scan and a battery of neuropsychological tests. Nine uninjured control subjects received similar testing. Patients 18-50 years of age were included if they had a post-resuscitation Glasgow Coma Scale >13 and an injury mechanism compatible with mTBI. Healthy controls were either age- and gender-matched family members of the TBI patients or healthy volunteers. CUD deficits >2 standard deviations (SD) were seen in 40.9% of patients. The CUD of injured patients correlated with mean diffusivity (MD) (p < 0.001, ρ = -0.811) in the posterior corpus callosum. Patients could be stratified on the basis of CUD on the Stroop 1, Controlled Oral Word Association Test (COWAT), and the obsessive-compulsive component of the Basic Symptom Inventory tests. These studies suggest that the PVRT indirectly measures white matter integrity in the posterior corpus callosum, a brain region frequently damaged by mTBI.

“…Various kinds of interhemispheric cysts have been reported and are often associated with agenesis of the corpus callosum [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]. Among these cysts, epithelial cysts, in association with agenesis of the corpus callosum, are rarely reported [1, 2, 3, 4, 5, 6, 7, 8].…”

“…Among these cysts, epithelial cysts, in association with agenesis of the corpus callosum, are rarely reported [1, 2, 3, 4, 5, 6, 7, 8]. The histological features of these cysts are varied, being diagnosed with the terminology of ependymal [5, 6], glioependymal [1, 8], choroidal epithelial [4]and neuroepithelial cysts [7].…”

“…A review of the terms employed in the reports discloses a variety of pathologies: 4 epithelial cysts with a lining resembling tela choroidea with choroid plexus tufts [2], 2 ependymal cysts [5, 6], 2 glioependymal cysts [1, 8], 1 choroidal epithelial cyst [4], 1 neuroepithelial cyst containing choroid plexus epithelia [7]and 1 epithelial cyst [3]have been reported when the cyst is lined with a single layer of cuboidal or columnar epithelium, whether or not cells were ciliated. The term glioependymal cyst has been used for those cysts with neuroglial walls and an inner lining of ependyma [15].…”

“…Ventriculomegaly was detected in 3 cases by prenatal ultrasonography. Several anomalies were associated including neocortical maldevelopment such as microgyria, cerebellar hypoplasia, neuronal heterotopia and VATER association (vertebral defects, anal atresia, tracheoesophageal fistula, radial or renal dysplasia) [2]. …”

This report describes a neonatal case in whom a large interhemispheric cyst associated with agenesis of the corpus callosum was revealed by fetal ultrasonography and demonstrated by MRI to be multilobulated. Endoscopic fenestration of cysts was initially designed in view of the development of the patient’s brain and surgical invasiveness. One year later, when motor paresis of the left arm and progressive enlargement of the cyst on MRI were revealed, open surgery was performed. The histological diagnosis was a neuroepithelial cyst with the feature of choroid plexus epithelia. The clinicopathological features of interhemispheric epithelial cysts associated with agenesis of the corpus callosum are reviewed in the light of differential diagnosis and therapeutic considerations.
