Radiological investigation of sellar region masses in children.

The treatment and prognosis of sellar region masses in children differ according to the type of tumor, and thus accurate determination of the extent and characteristics of the lesion is important. Evaluation by conventional skull radiography, complex-motion tomography, radionuclide imaging, computed tomography, cerebral air studies, and cerebral angiography has demonstrated definable characteristics of the various types of tumors and often allows distinction from benign processes.
