Intraoperative ultrasound (iUS) is a valuable tool-inexpensive, adds minimal surgical time, and involves minimal risk. The diagnostic predictive value of iUS is not fully characterized in Pediatric Neurosurgery. Our objective is to determine if surgeon-completed iUS has good concordance with post-operative MRI in estimating extent of surgical resection (EOR) of pediatric brain tumors. ⋯ The results from this study suggest that iUS is reliable with both residual tumor (PPV-100%) and when it suggests no residual (NPV-98%) in tumors that are easily identifiable on iUS. However, tumors that were difficult to visualize on iUS were potentially excluded, and therefore, these results should not be extrapolated for all brain tumor types.

Review Case Reports
Spontaneous rapid resolution of acute subdural hematoma in children.
Spontaneous rapid resolution of acute subdural hematoma developing secondary to trauma has been reported in the literature, yet it is very rare in pediatric population. The aim of the present review is to analyze mechanisms, characteristics, and outcomes of pediatric acute subdural hematoma cases with spontaneous rapid resolution in conjunction with an exemplary case of ours. ⋯ Analysis of 12 pediatric patients revealed a mean and median ages of 6.87 and 3.9 years, respectively (range = 8 months-18 years). Causes for ASH development were fall, traffic accident, struggle, and child abuse. Main clinical presentations were with depressed sensorium, coma, stupor, drowsiness, headache, motor weakness, lethargy, and seizure. Close follow-up with conservative treatment should be mode of approach in pediatric patients with ASH, if neurological and radiological findings are favorable. However, if patients' neurological status deteriorates after admission to hospital, surgery should be conveyed with no further delay.

Approximately 90% of concussions are transient, with symptoms resolving within 10-14 days. However, a minority of patients remain symptomatic several months post-injury, a condition known as post-concussion syndrome (PCS). The treatment of these patients can be challenging. The goal of our study was to assess the utility and cost-effectiveness of neurologic imaging two or more weeks post-injury in a cohort of youth with PCS. ⋯ In this cohort of pediatric PCS patients, brain imaging in the chronic phase (defined as more than 2 weeks after concussion) was pursued in almost half the study sample, had low diagnostic yield, and had poor cost-effectiveness. Based on these results, outpatient management of pediatric patients with long-term post-concussive symptoms should rarely include repeat neuroimaging beyond the acute phase.

Low brain oxygenation and differences in neuropsychological outcomes following severe pediatric TBI.
Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children. Preventing secondary injury by controlling physiological parameters (e.g. intracranial pressure [ICP], cerebral perfusion pressure [CPP] and brain tissue oxygen [PbtO2]) has a potential to improve outcome. Low PbtO2 is independently associated with poor clinical outcomes in both adults and children. However, no studies have investigated associations between low PbtO2 and neuropsychological and behavioural outcomes following severe pediatric TBI (pTBI). ⋯ Results demonstrate that low PbtO2 may be prognostic of not only mortality but also neuropsychological outcomes.
