This paper has two main purposes: (1) to report a rare case of paediatric gliosarcoma that invaded the surrounding orbit and (2) to demonstrate chlorpromazine injection as a potential treatment option for blind, painful eye caused by tumour invasion. A 12-year-old man who presented with headaches was found to have glioblastoma multiforme and it was excised and treated with radiation and chemotherapy. Seven months later, the tumour recurred as gliosarcoma, a rare variant of glioblastoma multiforme containing distinct gliomatous and sarcomatous components. In spite of treatment, the tumour progressed and eventually invaded into the right orbit. He subsequently developed a proptotic, blind, painful eye and was treated with retrobulbar chlorpromazine injection, which provided immediate symptomatic relief.
