CT of intrasellar colloid cyst.
Colloid cysts are congenital lesions considered to be derived from the primitive neuroepithelium and are most frequently located in the anterior third ventricle. In this paper a case of colloid cyst with a intra/suprasellar location is presented. Computed tomographic characteristics of this lesion were strongly consistent with the classic features of colloid cysts, particularly when interpreted retrospectively after surgical and histopathological data became available. The unusual occurrence of a colloid cyst in this location supports the theory that epithelial cysts related to sella turcica are derived not solely from Rathke cleft but also from neuroepithelium.
