Figure 2.1 Axial FLAIR MRI brain showing ovoid, periventricular and juxtacortical lesions also involving the corpus callosum highly characteristic of MS lesions in this patient without classical clinical features of…
Figure 8.1 Axial FLAIR and T1 with gadolinium MRI brain shows abnormal signal within the left tegmentum of the pons with patchy peripheral enhancement without mass effect, with scattered T2…
Figure 9.1 Sagittal T2 MRI cervical spine shows a solitary area of increased T2 signal at the prior level of compression, now relieved by spinal decompressive surgery. Three-step assessment 1…
Figure 18.1 Case 1. Brain MRI FLAIR (a) and T2 sequences (b) showing punctate subcortical white matter lesions. None were located on the cerebellum or in the cerebellar or vestibular…
Figure 15.1 Brain CT showing two cortical strokes (left frontal lobe and right parieto-frontal lobe) and several subcortical vascular lesions. Discussion This patient had recurrent strokes and imaging evidence of…
Figure 6.1 MRI diffusion-weighted imaging shows acute ischemia in the primary motor cortex and in neighboring white matter along the MCA–anterior cerebral artery (ACA) boundary zone (arrow). Figure 6.2 CTA…
Figure 8.1 MRI scans of the head. (a) Diffusion-weighted MRI scan demonstrated minimal restricted diffusion involving the left posterior limb of the internal capsule. (b) The perfusion-weighted MRI demonstrated a…
– Eclampsia-associated vasoconstriction – Drug-induced angiitis (“angiitis” is a misnomer as there is no vessel inflammation) – Migraine “angiitis” (again, a misnomer) – Thunderclap headache with reversible vasospasm – CNS…
Figure 17.1 CT scan of the head demonstrating an acute intracranial hemorrhage in the medulla (a, axillary image), extending into the lower pons (b, sagittal image). The remainder of the…
