Simple choristoma of the anterior segment containing brain tissue.
We report an unusual case of a simple choristoma of the anterior segment that contained only brain tissue. The clinical characteristics and findings of pathological examination of this unusual ocular malformation were reviewed. A newborn girl was seen with a fleshy, highly vascular cystic mass arising from the inferior limbus and extending across the cornea. On a computed tomographic scan, gross disruption of the anterior segment was present, with subluxation of the lens into the cyst. Excision of the abnormal tissue was followed by evisceration; polyglactin (Vicryl) ball implantation; patch graft of the globe; and, later, prosthetic fitting. Pathologic findings showed a choristomatous malformation, containing only mature brain tissue. To our knowledge, a choristoma in which the sole constituent is brain tissue has not previously been reported.
