Pediatric supratentorial tumors

There is a multitude of variables that must be taken into account when interpreting an imaging study and deriving a differential diagnosis. These include the clinical as well as the imaging findings. An intelligent analysis of the imaging findings, whether CT or MR, and whether enhanced or not, will, in most cases, narrow the differential diagnosis. The imaging information, when taken along with the clinical information, should provide guidelines as to the next step, diagnostic or therapeutic. Ultimately, there is no substitute for histologic characterization when the diagnosis remains unresolved and there is a need to institute treatment.
