The mean diameter of the third ventricle was 4.0 mm (SD 1.7 mm), when
measured with MRI, and 4.4 mm (SD 1.7 mm), when measured Selleckchem Tanespimycin with TCS. The 95% limits of agreement of the Bland-Altman Plot were 2.93 mm (95% CI 2.08 to 3.78 mm) and −2.23 mm (95%CI −3.08 to −1.38 mm). Pearson correlation coefficient was .71 (P < .0001). TCS may appear suitable as screening examination for the extent of brain atrophy at a single-point study, but at least in the early stages of the disease, TCS is not useful to monitor disease progression.

“NF2 is an autosomal dominant disorder with neuroectodermal dysplasia. Most patients present with characteristic clinical tumors during or beyond the adolescent age group. The diagnosis is mainly clinical. Vasculopathy is rarely associated with NF2. Vascular complication as the presenting symptom in NF-2
is unknown. We report a case of a 2-year-old child with no prior family history of neurofibromatosis presenting with ataxia and brain-stem stroke. “
“Contrast neurotoxicity (CN) following exposure to iodinated contrast is uncommon, and usually presents as cortical blindness due to bilateral occipital lobe involvement. Unilateral cortical dysfunction due to CN could mimic an acute stroke and has been rarely described. We report the case of an 89-year-old female who developed a transient dense/complete left homonymous-hemianopsia and left-sided SB203580 datasheet tactile extinction after undergoing a right internal carotid (ICA) artery rotational angiogram with a standard high-volume iodinated contrast injection for 3D visualization a 6×4-mm right posterior
communicating artery aneurysm with a fetal posterior selleckchem cerebral artery (PCA) incorporated in the neck. This was associated with transient fullness and loss of gray-white matter differentiation in the right occipital and parietal lobes. The potential mechanism of CN in our case was the injection of a high volume of contrast in the ICA for the rotational angiogram. The presence of a right fetal PCA possibly allowed the contrast to reach the right occipital lobe. CN manifesting as an acute focal neurologic syndrome should be considered in the setting of recent iodinated contrast exposure. “
“The hallmark radiological finding in metastatic brain disease is multiple enhancing lesions. We report a case of metastatic lung cancer to the brain with a lack of contrast enhancement. We believe that this unusual finding is due to inadvertent “treatment” of the metastases with the antiangiogenic agent bevacizumab (Avastin). “
“We present a case of a symptomatic venous aneurysm that developed in the drainage network of a deep-seated basal ganglia and thalamic arteriovenous malformation. The venous aneurysm was treated selectively with platinum coils using a venous approach. “
“Ganglioneuromas are uncommon, benign, and highly differentiated tumors arising from sympathetic ganglia.
