Extracranial internal carotid artery occlusive disease usually produces stroke in the middle cerebral artery territory or the border zone between the middle and anterior cerebral arteries. It is unusual for occipital infarction in the posterior cerebral artery territory to be caused by internal carotid artery disease despite the fact that the posterior cerebral artery may arise directly from th...

Visually directed pointing has been examined in a group of patients with occipital lobe infarction and in an age-matched control group. The visual field ipsilateral to the infarct showed normal localisation; there was no evidence that right sided infarction produced a bilateral disturbance. In quadrantanopia the spared quadrant on the affected side showed abnormal localisation in a few patients...

The presence of hemichorea associated with a lesion in the cortex is exceedingly rare. We report a case of a 62-year-old female who developed delayed left hemichorea after an ischemic infarct in the right temporal–occipital lobe. This case is unique because of the location of infarct and expands our knowledge of hemichorea arising after an ischemic stroke. A 62-year-old female patient was initi...

occipital neuralgia is a condition manifested by chronic occipital headaches and is thought to be caused by irritation or trauma to the greater occipital nerve (gon). treatment for occipital neuralgia includes medications, nerve blocks, and pulsed radiofrequency ablation (prfa). landmark-guided gon blocks are the mainstay in both the diagnosis and treatment of occipital neuralgia. ultrasound is...

Stroke occurs due to the interruption of blood flow to the brain and it is divided into ischemic and hemorrhagic. In the ischemic strokes, while the most commonly affected vessel is median cerebral artery (MCA), it is particularly affected bilateral posterior cerebral artery (PCA) is very rare condition. In this study, a case of sudden loss of vision and bilateral occipital infarct associated w...

OBJECTIVE To assess the temporal course of homonymous visual-field defects due to occipital lobe infarction, by using automated perimetry. METHODS 32 patients with ischaemic infarction of the occipital lobe were studied prospectively, using a Humphrey Visual Field Analyser II. The visual field of each eye was divided into central, paracentral and peripheral zones. The mean visual sensitivity ...

BACKGROUND Structural anomaly of the cervical spine or craniocervical junction has been reported as one of the rare causes of ischemic stroke. We report a case of a young patient with recurrent posterior circulation infarction that may have been associated with an anomalous occipital bony process compressing the vertebral artery. CASE PRESENTATION A 23-year-old man experienced recurrent poste...
