A 23-year-old female university student was admitted to the Department of Neurology with near vision difficulty and fatigue for 2 months. She was on neither eye drops nor any systemic medication. Her medical history revealed that she had presented to her physician with left shoulder pain six months ago. A mediastinal mass was found and a thymectomy was planned. She had an erythrocyte sedimentation rate (ESR) of 70 mm/h, moderate leukopenia (2600/uL) and thrombocytopenia (118,000/uL) at that time. Hematological investigations including bone marrow aspiration and biopsy all appeared normal. A thymectomy was performed through left sided thoracotomy. The mass was a benign thymoma (type B1) with cystic components. A left sided Horner's Syndrome developed just after the surgery and resolved over time. She reported a six to eight kilogram weight loss in four months following the operation. Two months after the operation she noticed difficulty with near vision.
