Pinealoma.

A patient was admitted to the Emergency Department of the Montreal General Hospital and referred to the Ophthalmology Clinic. He reported disorientation, dizziness, frontal headaches, and near vision problems. He had reduced near vision, binocular vision anomalies, Collier's sign, and abnormal pupil sizes, shapes, and responses. A diagnosis of pinealoma with a poor prognosis due to metastases was made.
