Brainstem edema in hypertensive encephalopathy usually occurs in association with typical supratentorial parieto-occipital changes and is usually asymptomatic. Bethesda, MD 20894, Help 2019;10:804. Check for errors and try again. Widespread involvement on imaging can raise the consideration of encephalitis or vasculitis, such as systemic lupus erythaematosus; however, relative acute presentation, reversible diffusion restriction on DWI and variable enhancement on post-gadolinium study can differentiate between them . Eiji Matsushita, Kosaku Takita, Akira Shimada. Knowledge of the imaging appearances of various toxic injuries to the brain may help narrow the differential diagnosis in a case of acute encephalopathy. It is cranio-caudally made up of diencephalon-midbrain, pons, and medulla. Objectives: To examine the clinical characteristics of autoimmune encephalitis associated with the glutamate decarboxylase 65 (GAD 65) antibody. Posterior reversible encephalopathy syndrome (PRES) refers to a potentially reversible neurotoxic state occurring in association with vasogenic cerebral edema. Neurological manifestations, commonly seen with serotypes 2 and 3. This user-friendly book includes basic information often omitted from other texts: a practical method of image analysis, sample dictation templates and didactic information regarding lesions/diseases in a concise outline form. Diffusion-weighted imaging (DWI) determined that diffusion was also partially restricted (Fig. Japanese encephalitis (JE) is the commonest endemic encephalitis in southeast Asia, including India [1]. Hitoshi S, Iwata M, Yoshikawa K. Mid-brain pathology of Wilson's disease: MRI analysis of three cases. 2011; 261:235–42. We used conventional sequences like T1WI, T2WI, FLAIR and DWI in all cases. Probst C, Saschenbrecker S, Stoecker W, Komorowski L. Anti-neuronal autoantibodies: Current diagnostic challenges. Medical records of all patients that diagnosed with GAD 65 antibody-associated encephalitis were retrospectively analyzed. CSF analysis revealed lymphocytic pleocytosis, normal glucose levels, and increased protein levels. Data regarding demographics and symptoms, neurological signs, laboratory and imaging results, treatment and prognosis were collected. Rabies is an endemic in the Indian subcontinent and rabies encephalitis can be detected reasonably early through MRI of the brain. Rabies involves predominantly the grey matter nuclei of the basal ganglia, thalamus, mid-brain and pons. In primary encephalitis, the virus directly involves the CNS. The face of the giant panda sign in neuroimaging refers to the appearance of the midbrain, when the red nucleus and substantia nigra are surrounded by high T2 signal in the tegmentum.. Materials and methods: Medical records of all patients that diagnosed with GAD 65 antibody-associated encephalitis were retrospectively analyzed. It contains numerous cranial nerve nuclei and is traversed by multiple tracts between the brain and spinal cord. 2019;21(5):437-442.

Knowledge of the vascular territories is important, because it enables you to recognize infarctions in arterial territories, in watershed regions and also venous infarctions. MRI was carried out on a 1.5 T system within 10-60 days of onset. Psychiatr. It is also the story of how one brilliant man, Syria-born Dr Najar, finally proved - using a simple pen and paper - that Susannah's psychotic behaviour was caused by a rare autoimmune disease attacking her brain. 4. Imaging and cytological examinations are important for the diagnosis of JE. “Midbrain imaging might be a way in the future to diagnose injury from a single concussive head hit, as well as from repetitive sub-concussive head hits.” ‘Silent brain injuries’ Found insideThis practical, comprehensive and highly illustrated book will be invaluable to students and doctors of neurology and internal medicine in Africa.
