Centrum semiovale lesion
What are cerebral white matter lesions?
Cerebral white matter lesions can be a harmless secondaryfinding or overture to a severe neurological disease. The comparative image analysis of different sequenceswith identical angulation is crucial. With special regard to the vascular anatomy, different le-sion patterns can be identified.
Which CT scan shows focal hypodensity in periatrial centrum semiovale?
Fig. 1.-A, Contrast-enhanced CT scan suggests focal hypodensity in periatrial centrum semiovale on the right in 5-year-old boy who presented with a history consistent with acute disseminated encephalomyelitis (arrows).
Which vascular diseases exhibit angiocentric lesion pattern on T2 WI?
Vascular-associated diseases as well as inflammatory and neoplas-tic processes may exhibit an angiocentric lesion pattern on T2 WIdue to the anatomically predetermined propagation along thePVS, which is illustrated by taking into account the T1 WI aftercontrast application (pc T1 WI) [39, 66–69]. In addition to sarcoi-dosis (see▶Fig.

In the preterm group, the number of lesions was < 3 in 20%, 3–10 in 27%, and > 10 in 53%. In 14/15 the lesions were linearly organised and located in the centrum semiovale. Other brain abnormalities were absent or minor—that is, “isolated” punctate lesions—in 8/15 and major in 7/15.

so-called rosary-like pattern in the centrum semiovale. However, the relationships between cortical WS infarction and hemodynamic compromise appear more complicated. Thus, although severe hemodynamic compromise appears to underlie combined cortical and internal WS infarction, artery-to-artery embolism may play an important role in isolated ...

centrum semiovale (Fig. 1). A contrast-enhanced MRI (CE-MRI) scan showed a lesion within the left centrum semiovale, with apparent inhomogeneous enhancement and an irregular shape, whereas the surrounding edema showed no enhancement (Fig. 2). Magnetic resonance angiography (MRA) showed no apparent anomalies (Fig. 3).

White matter lesion (WML) in magnetic resonance imaging is commonly observed in patients with cerebral small vessel disease (SVD), but the pathological mechanism of WML in SVD is still unclear. We observed the metabolism and microscopic anatomy of white matter in SVD patients. Twelve subjects clinically diagnosed

matter is especially in the centrum semiovale and nearby the anterior horns border zone between superficial pial, deep sube-pendymal and basal lenticulostriate and thalamo-perforating ar-teries [10]. This makes these deep white matter regions particu-larly vulnerable to vascular compromise (including“Steiner’s Wetterwinkel”).

MR imaging revealed a lesion with a concentric pattern involving the right centrum semiovale with contrast enhancement (Fig 1). A few T2-weighted hyper- intense small lesions could be seen in the white matter. A ste- reotactic biopsy was performed and showed changes consistent with a glial tumor. The lesion was removed subtotally.
