\Supratentorial brain\Supratentorial brain part\The cerebrum is the regional structure of the brain, which is the adult equivalent of the forebrain or prosencephalon. It is constituted by the structural derivatives of the telencephalon and diencephalon including the cerebral hemispheres, epithalamus, thalamus, hypothalamus, lateral ventricles and third ventricle.

Partial epileptic seizure of occipital lobe with impairment of consciousness	Finding site	False	Occipital lobe structure	Inferred relationship	Some	1
A rare genetic neurological disorder characterised by late infancy to early-adolescence onset of prolonged, nocturnal seizures which begin with autonomic features (e.g. vomiting, pallor, sweating) and associate tonic eye deviation, impairment of consciousness and may evolve to a hemi-clonic or generalised convulsion. Autonomic status epilepticus may be the only clinical event in some cases.	Finding site	False	Occipital lobe structure	Inferred relationship	Some	1
Benign occipital epilepsy is a rare, genetic neurological disorder characterized by visual seizures and occipital epileptiform paroxysms reactive to ocular opening which present in infancy to mid-adolescence. Vomiting, tonic eye deviation and impairment of consciousness are typically associated with the Panayiotopoulos type, while visual hallucinations, ictal blindness and post-ictal headache are commonly observed in the Gastaut type. Electroencephalographic findings in both types are similar and include bilateral, synchronous, high voltage spike-wave complexes in a normal background activity located predominantly in the occipital lobes.

A rare genetic neurological disorder with characteristics of childhood to mid-adolescence onset of frequent, brief, diurnal simple partial seizures which usually begin with visual hallucinations (e.g. phosphenes) and/or ictal blindness and may associate non visual seizures (such as deviation of the eyes, oculo clonic seizures), forced eyelid closure and blinking and sensory hallucinations. Post-ictal headache is common while impairment of consciousness is rare.	Finding site	True	Occipital lobe structure	Inferred relationship	Some	1

A rare, genetic, multiple congenital anomalies/dysmorphic syndrome characterized by occipital atretic cephalocele associated with a specific facial dysmorphism (consisting of prominent forehead, narrow palpebral fissures, midface deficiency, narrow, malformed ears, broad nose and nasal root, grooved nasal tip and columella, laterally angulated, hypoplastic nares, short philtrum, thin upper lip, clift lip/palate, severe oligodontia, prominent chin) and large feet with sandal gap. Intellectual disability, developmental delay and hypoplastic finger and toenails have also been reported.	Finding site	False	Occipital lobe structure	Inferred relationship	Some	2
Lethal occipital encephalocele-skeletal dysplasia syndrome is a rare, genetic, bone development disorder characterized by occipital and parietal bone hypoplasia leading to occipital encephalocele, calvarial mineralization defects, craniosynostosis, radiohumeral fusions, oligodactyly and other skeletal anomalies (arachnodactyly, terminal phalangeal aplasia of the thumbs, bilateral absence of the great toes, pronounced bilateral angulation of femora, shortened limbs, advanced osseous maturation). Fetal death in utero is associated.	Finding site	False	Occipital lobe structure	Inferred relationship	Some	4

An epileptic seizure originating within unilateral networks limited to the occipital lobe. Seizures arising in the occipital lobe are characterised by subjective visual phenomenon and/or oculomotor features such as forced eye closure, eyelid fluttering, eye deviation and nystagmus.

Primary malignant ependymoma of occipital lobe	Finding site	True	Occipital lobe structure	Inferred relationship	Some	1
A rare occipital epilepsy syndrome with onset most commonly between four and seventeen years (mean eleven years; range one to fifty years). Seizures are triggered by photic stimuli such as flickering sunlight. Focal sensory visual seizures which may evolve to bilateral tonic-clonic seizures are mandatory for the diagnosis. Focal sensory visual semiology includes colored spots, formed visual hallucinations, or visual blurring/loss that moves across the visual field. There is associated head and eye version. Seizures may progress to a cephalic sensation (including headache), autonomic epigastric sensation or vomiting, and impaired awareness or to a focal to bilateral tonic-clonic seizure. Seizures are typically brief (less than three minutes), although prolonged seizures may occur. Development and cognition are typically normal. Neurological examination is normal. The background electroencephalogram (EEG) activity is normal. Occipital epileptiform abnormalities facilitated by eye closure and intermittent photic stimulation are seen. Epileptiform activity is elicited by sleep deprivation and by sleep. MRI is normal or has nonspecific findings.	Finding site	True	Occipital lobe structure	Inferred relationship	Some	1
