Transient loss of consciousness (TLOC) is a common presentation to the emergency department and has a multitude of causes from benign to potentially fatal. We describe the case of a young female presenting with TLOC during sexual activity that was subsequently diagnosed with subarachnoid haemorrhage. She had normal neurology and only moderate headache. She was subsequently transferred to a neurosurgical unit and underwent endovascular coiling of a small anterior communicating artery aneurysm. She was discharged 15 days later without sequelae.
