Chemosis, proptosis and amaurosis in a 19-year-old male.

An ectopic pinealoma was excised in 1966 and the patient received radiotherapy postoperatively. The patient developed diabeted insipidus, hypopituitarism, chemosis, proptosis, and loss of vision in the left eye. The left eye was enucleated in 1974 and a large orbital mass was found to contain malignant cells consistent with the diagnosis of germinoma. The orbital mass was in all likelihood a metastasis from the original focus of the tumor.
