the hippocampus, caudate, and lentiform
nucleus), even on very low dietary levels of silicon, also support this possibility .
In our study, we found that in right frontal white matter, myoinositol levels are increased in bipolars relative to normals, and in the right lentiform
nucleus, NAA, glutamate+glutamine (the levels are so low these compounds are often considered together), and creatine are all decreased in bipolars relative to normals.
Klinik takibinde jeneralize tonik klonik konvulziyon gecirdi, sol kol ve bacaginda gucsuzluk gelisti, bu olayla birlikte bas agrisi yeniden siddetlendi ve kranyal MR'inda sag lentiform
nukleus ve sag kaudat nukleusta T1 de izo-hipointens, kontrastli T1'de kontrast tutulumu gosteren, T2 ve FLAIR agirlikli incelemelerde hiperintens iskemi ile uyumlu lezyonlar saptandi (Resim 1).
A brain scan showed an infarct in the right lentiform
nucleus with involvement of the head of the caudate with marked sinusitis.
Single voxel stimulated echo acquisition mode (STEAM) acquisition of the right lentiform
nucleus for magnetic resonance spectroscopy revealed diminished N-acetylaspartate (NAA), suggestive of neuronal loss/dysfunction (Fig.
In the right frontal white matter, myo-inositol was significantly increased, and in the right lentiform
region, N-acetylaspartate, glutamate/glutamine, and creatine were significantly decreased in bipolar patients, compared with healthy normals, Dr.
Magnetic resonance imaging disclosed a large, left frontal, lentiform
, extra-axial mass abutting the brain with underlying edema.
On CT it appears as well-defined lentiform
hypodense lesion with peripheral ring enhancement in extracoronal space adjacent to the bony orbital wall.
Signs of acute infarction include obscuration of normal brain structures, such as the insular ribbon (2) and lentiform
nucleus, (3) hyperdense artery, (4) or in less acute cases, parenchymal hypodensity and mass effect (Figure 1).
Lacunar infarcts were seen in the right lentiform
nucleus and thalamus and in the superficial white matter.
The MRI imaging showed no differences between bipolar subjects and controls in total brain volume, cerebellar volume, lentiform
nucleus, corpus callosum area, cerebellar vermis area, or thalamic area.
One of the early CT findings in acute Middle Cerebral Artery (MCA) infarction is that of obscuration of lentiform
nucleus, which is due to cellular oedema in the basal ganglia.
