ReviewTumor and Tumorlike Masses in Pediatric Patients that Involve Multiple Spaces.
There are several tumors and tumorlike masses involving multiple spaces in the pediatric brain. Accurate diagnosis of tumors and distinguishing them from tumorlike masses is an important aspect in the diagnostic workup and plays a key role for management and prognosis. Neuroimaging plays an important role in (1) identification of a brain mass, (2) determining its location, (3) demonstrating involvement of a single space versus multiple spaces, and (4) distinguishing a tumor from tumorlike masses.
