Fig. 18.1 Acute infarct. Diffusion-weighted images showing acute lacunar infarct (arrow) in posterior limb of right internal capsule Less common etiologies, representing less than 5 % of acute stroke, include vasculopathies, immune-related diseases, hypercoagulable states, arterial dissection, global hypoperfusion, venous infarction, and mitochondrial disorders.

Differentiating hemorrhagic infarct from parenchymal intracerebral hemorrhage can be difficult. The immediate and long-term management of the two conditions are different and hence the importance of accurate diagnosis. Using a series of intracerebral hemorrhage cases presented to our stroke unit, we aim to highlight the clues that may be helpful in distinguishing the two entities. The main

Postictal headache occurs in more than half of patients (epilepsy–migraine sequence). An occipital nerve block is a relatively safe and simple procedure to block the occipital nerve to help diagnose and treat certain types of head pain. There are 2 greater occipital nerves, on each side of the head. These emerge from between bones of the spine in the upper neck. 2014-07-01 · Yet, this study considerably extends our knowledge about occipital, occipito-temporal and occipito-parietal infarction through detailed descriptions of infarct topography, neurological, neuropsychological symptoms, and importantly, the definition of anatomical correlates of neuropsychological dysfunction by using a lesion-symptom mapping approach. The occipital bone is composed of the basiocciput, supraocciput, exocciput, and occipital squamosa.

Occipital infarct radiology

In 1988, Anderson and Montesano [ 13 ] described their classification system in six patients who had occipital condyle fractures. 2018-11-01 The occipital lobe covers 12% of the neocortex, which is involved in cognition, reasoning, motor skills, and sensory perception (6). The right and left occipital lobes are separated by a cerebral fissure (7). The parietal lobe, temporal lobe, and occipital lobes are medially separated by a deep groove called the parieto-occipital sulcus (8). 2018-11-01 Watershed infarct: T1 MRI of an ischemic stroke in the brain without (left) and with (right) contrast.

We describe a classic case of selective apperceptive prosopagnosia due to an ischemic infarct of the left occipital lobe with extension to the lingual gyrus. It is well-established that acquired prosopagnosia usually involves the right more than the left occipital cortex, with localization of lesions bilaterally more than unilaterally.

Since most patients in previous reports were not studied with CT, it is impossible to say how often these patients will have residual occipital infarctions. Our two cases suggest that … Anatomy of the CCJ. Understanding the anatomy of the CCJ is essential to adequately evaluate the patient for potential injuries.

Low density of the left hemisphere correlates with the anatomical position of the whole middle cerebral artery (MCA) territory; Hyperdense MCA sign due to thrombus; The infarct is causing swelling of the brain with mass effect - effacement of the sulci and ventricles with shift of midline structures to the right occipital infarct in the PCA territory likely caused by local embolism from a subtotal ICA occlusion. Our patient's right PCA also filled from the basilar artery, making embolism from the posterior circu-lation a possibility. However, the absence of verte-brobasilar atheromatous disease on angiography or 2015-05-28 · resulting from bilateral lesions of the striate cortex in the occipital lobes. In most cases, these patients deny their blindness and their behavior is as if they have an intact vision. We report the case of an 84-year-old man with bilateral cortical blindness resulting from bilateral occipital lobe infarcts. The patient presented Function films of the atlanto-occipital joint may show fixation or moderate or normal movement of the nonfused part of the arch of C-l (Fig. 1).

The involvement of the medial aspect of the occipital lobe (arrow) indicates posterior cerebral artery territory. This lesion may represent an asymmetrical watershed lesion. Cortical blindness, a particular type of cerebral blindness, is defined as the total loss of vision in the presence of normal pupillary reflexes and in the absence of ophthalmological disease [2], resulting from bilateral lesions of the striate cortex in the occipital lobes [1].

The main clue to the presence of hemorrhagic infarct on computed tomography scan is the topographic distribution of the stroke. Additional imaging modalities such as computed tomography angiogram, perfusion, and magnetic resonance imaging may provide additional information in differentiating hemorrhagic infarct from primary hemorrhages.

Findings are suggestive of occipital meningocele herniating through a small cranial defect with moderate ventriculomegaly and a suspected small sacral meningocele. Prenatal MRI is valuable in cases of cystic lesions related to the head & neck as it delineates findings that can't be accurately assessed using ultrasound and helps to differentiate between cervical cysts (e.g cystic hygroma ) and 2011-10-17 Radiology Cases and Radiology Case Reports. Dr Balaji Anvekar FRCR Neuro and MSK Consultant Radiologist. Monday, 24 September 2012.

Seven patients, each with a different pattern of homonymous visual loss caused by ischemic infarction of the occipital lobe, were studied with computed tomography. The retinotopic representation of the visual field on the occipital lobes, as determined by these studies, fully confirms those deduced by previous investigators.
