Summary
AI-generated from the abstractA 33-year-old man with a right frontal lobe oligodendroglioma experienced complex partial seizures involving a feeling of being projected outside his body, dissociation of mind and self from body (disembodiment), and vestibular vertigo. The case distinguishes these ictal symptoms from autoscopic phenomena such as out-of-body experiences, heautoscopy, and autoscopic hallucinations, and from vestibular phenomena of epileptic origin. The neural origins are discussed in relation to vestibular and multisensory cortical mechanisms of bodily self-consciousness in the temporoparietal and frontal cortex.

Abstract
We describe the case of a 33-year-old man with complex partial seizures characterized by the feeling of being projected outside his body, including dissociation of "mind and self from body" (disembodiment), followed by vestibular vertigo due to right frontal lobe epilepsy caused by an oligodendroglioma. We distinguish the patient's ictal symptoms with respect to autoscopic phenomena (out-of-body experience, heautoscopy, autoscopic hallucinations) and vestibular phenomena of epileptic origin, and we discuss their neural origin with respect to vestibular and multisensory cortical mechanisms of bodily self-consciousness in temporoparietal and frontal cortex.
