[Tumors of the sellar and pineal regions]

Area of Science:

• Neuro-oncology
• Pediatric Radiology

Context:

• The (supra) sellar and pineal regions are common sites for pediatric brain tumors.
• The spectrum of lesions in these areas differs markedly between pediatric and adult populations.

Purpose:

• To highlight the distinct types of space-occupying lesions in the pediatric (supra) sellar and pineal regions.
• To emphasize the critical role of imaging in the early detection and characterization of these pediatric brain tumors.

Summary:

• Craniopharyngioma is the most frequent intrasellar/suprasellar lesion in children, unlike pituitary adenomas common in adults.
• Germ cell tumors predominantly affect the pediatric pineal region, whereas in adults, they are mainly gonadal.
• Imaging aids in early detection, lesion characterization, and anatomical delineation of pediatric brain tumors in these critical regions.

Impact:

• Improved understanding of age-specific brain tumor epidemiology in the (supra) sellar and pineal regions.
• Enhanced diagnostic accuracy through precise imaging of pediatric brain lesions.
• Facilitates timely and appropriate treatment planning for children with brain tumors.
