The area and volume of the sella turcica in childhood primary hypothyroidism.

Sellar area and volume are compared to chronological age, stature, and osseous maturation (bone age) in a series of control children of short stature and in those with primary hypothyroidism and idoiopathic pituitary deficiencies. Sellar area is increased most significantly in relation to bone age in primary hypothyroidism; volume is less useful than area in the diagnosis of this disease.
