Typical tumors of suprasellar region of a child
Craniopharyngiomas are cystic lesions that often contain calcium. These may be confused with Rathke cleft cysts, which are remnants of the Rathke pouch, the structure that forms the anterior portion of the pituitary gland. Other tumors include tumors of hypothalamic origin (gliomas or hamartomas), optic nerve tumors (e.g., tumors seen in NF-1), germinomas arising from the pituitary stalk, and pituitary adenomas. Langerhans cell histiocytosis (eosinophilic granuloma) can manifest as thickening of the infundibulum and loss of visualization of the normal posterior pituitary bright spot on T1-weighted images and is associated with a clinical history of growth delay.
