Pineal cysts are usually asymptomatic; however, they may rarely cause symptoms such as chronic headache, paroxysmal headache with gaze paresis, postural syncope, loss of consciousness, and sudden death. A 30-year-old woman with no specific medical history except chronic headache was found collapsed in a public toilet per se. Postmortem examination revealed no external injuries or internal diseases except a cystic lesion of the pineal gland. Histologic examination showed an internal cyst surrounded by glial tissues and pineal parenchyma that was diagnosed as a glial cyst of the pineal gland. Although the pineal cyst cannot be confirmed as the cause of death, it was considered, as no other cause was evident. Herein, we report a pineal cyst considered as an assumed cause of death.
