Colobomatous microphthalmia and orbital neuroglial cyst: case report.

We present the case of a boy with a congenital right orbital cyst with bilateral colobomatous microphthalmia. Neuroimaging studies excluded communication between the cyst and the eye and between the cyst and the central nervous system. Analysis of cyst fluid obtained by aspiration detected beta 2-transferrin by high resolution immunofixation (IFE). The cyst recurred two months following aspiration. It was then completely excised and histopathologic studies demonstrated a cyst containing neuroglial tissue. No recurrence was observed for 12 months following excision.
