“…In the present study i.e table 3,the most common neurological deficit -hemiplegia or hemiparesis was found in 34 cases (i.e 68%) and in accordance with study by Abraham et al(1970) and Chopra et al (1979) (5,6) . The most common CT finding was an acute cortical infarction seen in 27 cases (i.e54%) and the second most common finding was lacunar infarction seen in 14 cases i.e 28% and was accordance with study done by Regli L et al 1993 (7) . Hemorrhagic stroke accounted for 3 cases i.e 6 % and was correlated to study by Ladurner G et al and Regli L et al (15-25%) who found the same finding (7,8) .…”

“…Acute lacunar infarct could be seen either as a hyperintense lesion or a lesion which has a central hypointensity and a hyperintense surrounding rim representing gliosis 6 . Contrast enhancement could persist up to eight weeks after the acute episode 19 . In addition, dilated VRSs are more circular or linear while lacunar infarcts are wedge-shaped 1,4,11 .…”

Virchow-Robin spaces are lesions often seen in the brain parenchyma but their etiopathogenesis remains unsettled. Giant Virchow-Robin spaces placed in the midbrain are extremely rare. We describe three patients with a diagnosis of giant Virchow-Robin spaces in the midbrain, and their clinical and radiologic findings. We reviewed the literature in terms of the etiopathology, anatomic and radiologic appearance and differential diagnosis of the giant Virchow-Robin spaces. The diagno-stic role of the high Tesla magnetic resonance devices and new sequences techniques such as three dimensional isotropic acquisition and diffusion tensor imaging were also evaluated in this case series.

“…Due to their small size, they are often not recognized on CT scans. Some early subacute lacunar infarctions may enhance following contrast administration [45]. On MR scans they are seen as round lesions, hyperintense on T2-weighted sequences (Fig.…”

Non-traumatic neurological emergencies: imaging of cerebral ischemia

Cardiovascular disease is the leading cause of death worldwide with almost one-third of all cardiovascular deaths ascribed to stroke. Imaging modalities, such as CT, MRI, positron emission tomography (PET), and single photon emission CT (SPECT) provide tremendous insight into the pathophysiology of acute stroke. Computed tomography is considered the most important initial diagnostic study in patients with acute stroke, because underlying structural lesions, such as tumor, vascular malformation, or subdural hematoma, can mimic stroke clinically. Diffusion-weighted imaging (DWI) has the ability to visualize changes in diffusion within minutes after the onset of ischemia and has become a powerful tool in the evaluation of patients with stroke syndrome. Territories with diffusion and perfusion mismatch may define tissues at risk, but with potential recovery. An alternative strategy with CT technology uses rapid CT for dynamic perfusion imaging, with similar goals in mind. Angiography can be performed in the hyperacute stage if thrombolytic therapy is being considered. Indications for diagnostic angiography include transient ischemic attacks in a carotid distribution, amaurosis fugax, prior stroke in a carotid distribution, a high-grade stenotic lesion in a carotid artery, acquiring an angiographic correlation of magnetic resonance angiography (MRA) or computed tomographic angiography (CTA) concerning stenotic findings. In 50% of all angiograms performed in the hyperacute stage, occlusion of a vessel is observed; however, the need for angiography has been made less necessary due to the improvements of MRA, duplex ultrasound, and CTA. Numerous etiologies can lead to infarction. In children, pediatric stroke is very uncommon. The most common cause is an embolus from congenital heart disease with right-to-left shunts. Also a dissection of large extracranial vessels may result in cerebral infarction, and although the brain is equipped with numerous venous drainage routes, the occlusion of a large sinus or a widespread vein obstruction will eventually lead to venous infarction. Thus, optimal stroke care requires not only early and exact identification of ischemia, but also a close collaboration between the clinician and radiologist.
