KJ is a 15-year-old boy. About a year ago, he lost his appetite, felt dizzy and had double vision. Brain imaging showed a 3.8 X 3.7 cam mass in the pineal region and a 1.3 cam mass in the supra-sellar region. KJ’s problem was diagnosed as extensive pineal gland germinoma with hypopituitarism and diabetes insipidus. The doctors suggested chemotherapy and radiotherapy but KJ’s parents refused further medical treatment.
