Midline shift of brain

Those who suffer from a concussion may expect headaches or changes in sleep patterns, at least for a few days. Unfortunately, even mild traumatic brain injuries (TBIs) can have much more severe consequences, including problems like Visual Midline Shift Syndrome. This condition affects many accident victims who experience a blunt force impact to the head and can cause vision and balance problems for years to come. Although often treatable, this kind of trauma-related brain injury can have significant repercussions for a person’s life. Those repercussions can be particularly frustrating for those who were injured in accidents through no fault of their own. If you are suffering from Visual Midline Shift Syndrome or another TBI-related medical condition, you could be entitled to compensation for treatment and therapy.

Visual Midline Shift Syndrome (VMSS) is a type of medical condition that causes a visual and sensory shift in the concept of someone’s bodily midline. Basically, the brain is unable to process visual and spatial information properly, causing someone to feel as though his or her center of balance is shifted too far in one direction. A common result of traumatic brain injury, VMSS can cause serious problems with balance and motor function, making it difficult to coordinate movements and maintain central balanc...

It may occur following traumatic brain injury in association with raised intracranial pressure or an intracranial hematoma which can push the brain towards one side causing a midline shift. Midline brain shifts cause extreme pressure on parts of the brain resulting in the blood supply to various parts of the brain being compromised. This can be fatal and is considered a medical emergency. Midline brain shift may be evident in neuroimaging such as CT scanning. The sign is considered ominous because it is commonly associated with a distortion of the brain stem that can cause Watch the video below to learn more: Symptoms of Midline Brain Shift Midline shift is often associated with high intracranial pressure (ICP), which can be deadly. In fact, midline shift is a measure of ICP; the presence of the former is an indication of the latter. https://en.wikipedia.org/wiki/Midline_shift The presence of midline shifts is an indication for neurosurgeons to take measures to monitor and control ICP. The main causes of elevated intracranial hypertension symptoms are papilledema and neurological irritation, compression, or displacement. Almost all cases of non-specific headaches are recorded, and they are probably mediated by the trigeminal nerve's Frequent transient visual abnormalities can cause one or both It is possible to report peripheral vision loss, which typically starts in the nasal inferior quadrant and progresses to loss of the central visual field. Visual acuity changes that ...

Midline shift is a term used to describe a shift of the brain structures to the side of the head. Normally the brain is symmetric from side to side and there are structures that are directly in the midline. This is a term that reflects raised pressure inside the skull which can be from a mass, bleed, infection or anything that shifts the midline structures to the side and causes the brain to look asymmetric. Shift of the midline structures on head CT reflects raised intracranial pressure which is a medical emergency. Many symptoms can accompany raised intracranial pressure and midline shift to include: headache, visual problems, decreased consciousness, nausea/vomiting and even death. The symptoms are non specific which can prompt extensive testing. When symptoms are thought to originate from the nervous system, a head CT is often ordered. A head CT showing midline shift will often look asymmetric and the normally midline structures will be shifted to the side. This is often measured between the septum pellucidum, which is a thin membrane between the lateral ventricles in the midline and the attachment of the falx cerebri along the front and back part of the skull which is also along the midline. If there is measurable distance between the septum pellucidum and falx attachments, then there is midline shift. Often the reason for the midline shift will also be seen on a head CT. Some of the common causes include a bleed, mass, infection, stroke to include some. A bleed along...

This is a basic article for medical students and other non-radiologists Intracranial mass effect describes what happens around a tumor in the brain. It is important to make the distinction between an abnormality that causes mass effect and compresses adjacent structures, and one that does not.

Emergency physicians frequently evaluate patients with complaints requiring brain imaging for diagnosis and treatment. The diversity of imaging modalities and variations of these modalities may be daunting, creating uncertainty about the most appropriate, sensitive, and specific modality to evaluate the presenting complaint. An evidence-based approach is essential, with modality and technique chosen based on patient characteristics and differential diagnosis. In this chapter, we begin with a brief summary of computed tomography (CT) and magnetic resonance (MR) technology. Next, we present a systematic approach to interpretation of head CT, along with evidence for interpretation by emergency physicians. Then, we discuss the cost and radiation exposure from neuroimaging, as these are important reasons to limit imaging. We review the evidence supporting the use of CT and magnetic resonance imaging (MRI) for diagnosis and treatment of emergency brain disorders, concentrating on clinical decision rules to target imaging to high-risk patients. We also consider adjunctive imaging techniques, including conventional angiography, plain films, and ultrasound. By chapter’s end, we consider the role of neuroimaging in the evaluation of headache, transient ischemic attacks (TIAs) and stroke, seizure, syncope, subarachnoid hemorrhage (SAH), meningitis, hydrocephalus and shunt malfunction, and head trauma. Neuroimaging Modalities Indications for neuroimaging are diverse, including traumat...

This topic has come up in As far as external FOAMresources go, one cannot go past Diagnosis of stupour and coma, the definitive resource for all information related to head injury. There, on page 95 of my tattered 4 th edition one may find Herniation syndromes: intracranial shifts in the pathogenesis of coma. The link is to a Googlebook which may not be complete. Another excellent article is this paper by Anyway: there are eight major patterns of herniation: • Falcine herniation • Lateral displacement of the diencephalon ("midline shift") • Uncal herniation • Central transtentorial herniation • Rostrocaudal brainstem deterioration • Tonsillar herniation • Upward brainstem herniation • Transcalvarial herniation(i.e. out of a defect in the skull) In brief summary, with only the most important features picked out: Herniation Radiological features Clinical features Subfalcine, or "midline shift" • Displacement of the cingulate gyrus under the falx cerebri • Midline shift of the septum pellucidum • Leg weakness • A decreased level of consciousness, proportional to the degree of shift. Uncal • Uncus and medial temporal lobe displaced medially • Effacement of the suprasellar cistern • The hippocampus obliterates the quadrigeminal cistern • midbrain effaced and displaced laterally • Ipsilateral fixed dilated pupil (3rd nerve palsy) • Decreased level of consciousness • Hemiparesis • Cortical blindness Central tentorial • Obliteration of basal subarachnoid cisterns • Increased brain...
