Pediatric Brain Tumors

Loyola Researchers Identify Common Characteristics, Outcomes of Rare Pediatric Brain Tumors

In a new study, “Pediatric vestibular schwannomas: case series and a systematic review with meta-analysis,” appearing in the Journal of Neurosurgery, researchers at Loyola University Medical Center and Loyola University Chicago Stritch School of Medicine performed a retrospective review of the diagnosis, treatment and outcomes of 15 patients (21 years of age or younger) with unilateral vestibular schwannomas, without neurofibromatosis type 2 (a genetic disorder that causes noncancerous tumor growth in the nervous system), who underwent surgery at Loyola University Medical Center between 1997 and 2019. The study authors also reviewed existing literature on this type of tumor in pediatric patients.

Overall, the review found that pediatric patients had similar symptoms to those of adult patients with acoustic neuromas; however, the tumor size was typically larger in the pediatric patients at the time of diagnosis, and symptoms of mass effect (secondary effects caused by the tumor) were
