Compared to the normal elderlies, ReHo values decreased in aMCI patients in the left temporal lobe (middle temporal gyrus and inferior temporal gyrus), left parahippocampal gyrus, occipital lobe
, lingual gyrus, precuneus, and other regions.
Encephalofacial angiomatosis sparing the occipital lobe
and without facial nevus: on the spectrum of Sturge-Weber syndrome variants?
Cranial magnetic resonance imaging (cMRI) revealed multiple areas of T2/ flair hyperintensity involving white matter in the posterior parietal lobes, occipital lobes
and cerebellar white matter (Fig.
Site-specific analyses suggested adverse associations between higher mean [PM.sub.10] over 1999-2007 or 1990-2007 and smaller total brain volumes, occipital lobe
volumes, and deep-gray volumes in Minnesota (Table 4).
(a) T1-weighted MR image demonstrating a hyperintense hematoma with hypointense core on the right occipital lobe
, compressing the occipital horn of the right lateral ventricle, (b) T2-weighted MR image showing hyperintense signals of the same hematoma with surrounding vasogenic edema, and (c) FLAIR MR images demonstrating cortical- subcortical signal abnormalities on the right as well as left occipital lobes
Significant main effects were found for lobe (F(3,54) = 10.66, p < 0.001; N2 amplitudes in the occipital lobe
and the parietal lobe were significantly larger than those in the frontal lobe (p <0.01) and temporal lobe (p < 0.05)) and hemisphere (F(1,18) = 5.50, p <0.001; N2 amplitude in the right hemisphere was significantly larger than that in the left hemisphere).
According to previous results , three electrodes (O1, Oz, and O2) at the occipital lobe
were analyzed in present study.
studied the ReHo of whole brain fMRI in patients with major depression and healthy controls at rest, and the results show that the ReHo values of the left thalamus, left temporal lobe, left cerebellar posterior lobe, and bilateral occipital lobe
in patients with depression were significantly lower than in healthy subjects, suggesting abnormal activity in these brain regions .
CT scan of the brain without contrast showed an infarct in the left occipital lobe
Fluid attenuated inversion recovery magnetic resonance imaging showed a high intensity signal in the sulci of the left parietal lobe and bilateral occipital lobe
(Figures 1(a) and 1(b)).
Brain MRI disclosed three ring-enhancing T1 and T2 hypointense cortical lesions, two located in the right frontal lobe and one in the left occipital lobe
, associated with vasogenic oedema and absent leptomeningeal enhancement (Figure 1).
On the seventh day, the patient was noted to have worsening neurological status and left extremity weakness and a repeat computed tomography (CT) scan revealed a right occipital lobe
hematoma with blood loss of 40 ml (Figure 4).
