The dorsum sellae in infancy and childhood

Abstract

Abslract. Evaluation of the dorsum sellae in infants and children is often difficult. Understanding its normal development and anatomy will help in the detection of pathologic states. The normal central concavity of the dorsum, normal pointing and tapering of the superior dorsum, variation in size and shape of the posterior clinoids, ossified dural bridging and a variable size of the dorsum occur at these ages. Changes associated with hydrocephalus, intrasellar and suprasellar turnouts in the early stage may mimic variations of the norm. Multiple tomographic sections and projections of the sella and clinical correlation are essential.

Qualitative and Quantitative Radio-Anatomical Variation of the Posterior Clinoid Process

“…The dorsum increases in size until puberty after which no significant change takes place. 7,14,15 Significant wide variations in the PCP in different individuals and even between the opposite sides of the same individual have been reported, such as fusion of the ACP and PCP through an ossified interclinoid ligament. 9,10 One study reported bilateral complete ossification of the interclinoid ligament in 6% of autopsy cases.…”
