Choroidal epithelial cyst of the cerebral hemisphere. An immunohistochemical study.
A case of choroidal epithelial cyst in the left cerebral hemisphere of a 4-month-old infant is described. The cyst wall was composed of a single epithelial layer with a basement membrane and fibrous connective tissue. An immunohistochemical study revealed the presence of prealbumin in the cytoplasm of these cuboidal epithelial cells. This fact strongly suggested that the cuboidal epithelium lining the cyst wall originated from choroidal epithelial cells. The diagnostic usefulness of the immunohistochemical study in choroidal epithelial cysts is discussed.
