1. Migration of lipiodol into lateral ventricles after embolization of cerebral arteriovenous malformation: a case report. (PubMed)

Migration of lipiodol into lateral ventricles after embolization of cerebral arteriovenous malformation: a case report. N-butyl cyanoacrylate (NBCA) has been used to embolise brain arteriovenous malformations (AVMs) for over 30 years. It is a mixed with lipiodol in varying proportions. We report a 22-year-old male with intraventricular hemorrhage from a ruptured intranidal AVM aneurysm in the left temporal lobe. The intranidal aneurysm and the nidus were successfully embolized using a 20% NBCA (...) and lipiodol mixture without any complications according to computed tomography (CT) immediately after treatment. Scattered high-density spots were observed in both lateral ventricles on CT 5 days after embolization, suggesting migration of lipiodol. We speculated that the aneurysm was a pseudoaneurysm whose wall protruded into the inferior horn of the left lateral ventricle, and the lipiodol in the NBCA migrated into the ventricles after the thin part of the wall ruptured. The patient developed pyrexia

2. A case of a cerebral cavernous malformation of the third ventricle that caused the syndrome of inappropriate secretion of antidiuretic hormone (PubMed)

A case of a cerebral cavernous malformation of the third ventricle that caused the syndrome of inappropriate secretion of antidiuretic hormone Cerebral cavernous malformations (CCMs, also known as cavernous hemanigiomas) of the third ventricle are uncommon. Here, we present a rare case of a CCM that caused the syndrome of inappropriate secretion of antidiuretic hormone (SIADH).A 68-year-old man presented with acute-onset cognitive and memory disturbance. Endocrinological examinations revealed (...) hyponatremia due to SIADH. Computed tomography indicated a high-density mass in the third ventricle that caused left unilateral hydrocephalus due to obstruction of the foramen Monroe. On magnetic resonance imaging, the mass showed high intensity in both T1 and T2-weighted images and low intensity in susceptibility-weighted images, suggesting subacute intralesional hemorrhage. We completely excised the mass via a basal interhemispheric translamina terminalis approach. Intraoperatively, the mass adhered

3. Cerebral near infrared spectroscopy is a reliable marker of systemic perfusion in awake single ventricle children. (PubMed)

Cerebral near infrared spectroscopy is a reliable marker of systemic perfusion in awake single ventricle children. Clinical assessment of systemic perfusion in single ventricle patients with parallel circulation can be difficult in the outpatient setting. Near infrared spectroscopy (NIRS) is a noninvasive measure of cerebral oximetry. We measured vital signs, pulse oximetry, and NIRS in 20 single ventricle patients with parallel circulation prior to routine cardiac catheterization (...) . These variables were evaluated to determine the best noninvasive predictor of the superior vena cava saturation (SVC(sat)) as a marker for the adequacy of systemic oxygen delivery. The mean age was 6.7 months [standard deviation (SD), 8.6] and mean weight was 6.5 kg (SD, 2.2). Diagnoses were hypoplastic left heart syndrome (8), tricuspid or pulmonary atresia (10), and double-outlet right ventricle variants (2), all prior to cavo pulmonary anastomoses or complete repairs.

4. Effect of Skull Type on the Relative Size of Cerebral Cortex and Lateral Ventricles in Dogs (PubMed)

Effect of Skull Type on the Relative Size of Cerebral Cortex and Lateral Ventricles in Dogs Volume measurements of the brain are of interest in the diagnosis of brain pathology. This is particularly so in the investigation hydrocephalus and canine cognitive dysfunction (CCD), both of which result in thinning of the cerebral cortex and enlarged ventricles. Volume assessment can be made using computed tomography or more usually magnetic resonance imaging (MRI). There is, however, some uncertainty (...) cranial cavity dimension) had a smaller ratio of cortical to ventricular volume (low C:V ratio) than breeds with lower CrI skull types. It is important to consider this effect of skull shape on the relative volume estimates of the cerebral cortex and ventricles when trying to establish if pathology is present.

6. Alcohol use is associated with thinner cerebral cortex and larger ventricles in schizophrenia, bipolar disorder and healthy controls. (PubMed)

Alcohol use is associated with thinner cerebral cortex and larger ventricles in schizophrenia, bipolar disorder and healthy controls. Excessive alcohol use is associated with brain damage but less is known about brain effects from moderate alcohol use. Previous findings indicate that patients with severe mental illness, particularly schizophrenia, are vulnerable to alcohol-related brain damage. We investigated the association between levels of alcohol consumption and cortical and subcortical (...) used to investigate associations between AUDIT-C score and cortical thickness, surface area, and total brain and subcortical volumes.Increasing AUDIT-C score was linearly associated with thinner cortex in medial and dorsolateral frontal and parieto-occipital regions, and with larger left lateral ventricle volume. There was no significant interaction between AUDIT-C score and diagnostic group. The findings remained significant after controlling for substance use disorders, antipsychotic medication

12. Perioperative cerebral hemodynamics and oxygen metabolism in neonates with single-ventricle physiology (PubMed)

Perioperative cerebral hemodynamics and oxygen metabolism in neonates with single-ventricle physiology Congenital heart disease (CHD) patients are at risk for neurodevelopmental delay. The etiology of these delays is unclear, but abnormal prenatal cerebral maturation and postoperative hemodynamic instability likely play a role. A better understanding of these factors is needed to improve neurodevelopmental outcome. In this study, we used bedside frequency-domain near infrared spectroscopy (...) (FDNIRS) and diffuse correlation spectroscopy (DCS) to assess cerebral hemodynamics and oxygen metabolism in neonates with single-ventricle (SV) CHD undergoing surgery and compared them to controls. Our goals were 1) to compare cerebral hemodynamics between unanesthetized SV and healthy neonates, and 2) to determine if FDNIRS-DCS could detect alterations in cerebral hemodynamics beyond cerebral hemoglobin oxygen saturation (SO 2). Eleven SV neonates were recruited and compared to 13 controls

13. Long-Term Migration of a Deep Brain Stimulation (DBS) Lead in the Third Ventricle Caused by Cerebral Atrophy in a Patient with Anterior Thalamic Nucleus DBS (PubMed)

Long-Term Migration of a Deep Brain Stimulation (DBS) Lead in the Third Ventricle Caused by Cerebral Atrophy in a Patient with Anterior Thalamic Nucleus DBS The long-term (5-years) antiepileptic effect of deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) against refractory epilepsy has been reported. However, experience with ANT DBS for epilepsy is limited, and so hardware complications and technical problems related to ANT DBS are unclear. We report the case of a 57 (...) -year-old male who underwent re-implantation of a DBS lead in the left ANT because of lead migration into the third ventricle detected 8 years after the first DBS, and which was caused by the significant enlargement of the lateral and third ventricles. After re-implantation, the patient showed a mechanically-related antiepileptic effect and a prominent driving response of the electroencephalography was verified. We speculate that progressive dilatation of the ventricle and shallow, insufficient

Ventricle contact is associated with lower survival and increased peritumoral perfusion in glioblastoma. OBJECTIVEThe purpose of this study was to prospectively investigate outcome and differences in peritumoral MRI characteristics of glioblastomas (GBMs) that were in contact with the ventricles (ventricle-contacting tumors) and those that were not (noncontacting tumors). GBMs are heterogeneous tumors with variable survival. Lower survival is suggested for patients with ventricle-contacting (...) tumors than for those with noncontacting tumors. This might be supported by aggressive peritumoral MRI features. However, differences in MRI characteristics of the peritumoral environment between ventricle-contacting and noncontacting GBMs have not yet been investigated.METHODSPatients with newly diagnosed GBM underwent preoperative MRI with contrast-enhanced T1-weighted, FLAIR, diffusion-weighted, and perfusion-weighted sequences.
