Further studies are required to evaluate whether this learn more promising

technique may be considered a reliable and accurate method to longitudinally evaluate patients with increased ICP secondary to IIH. “
“Although metastatic skull lesions of neuroblastoma are not uncommon, brain involvement is infrequent and prompt diagnosis is of utmost importance in such cases. Previous studies have shown that Meta-Iodo-Benzyl-Guanidine (MIBG) scans were not always reliable in detecting central nervous system metastases, however most published reports referred to the Iodine-131 (131I)-MIBG scans. Herein, we report an intraventricular metastasis of neuroblastoma diagnosed using an Iodine-123 (123I)-MIBG scan, which is increasingly being used in clinical practice and reported as a more accurate method for detecting metastatic ABT-888 molecular weight lesions. An unusual case of metastatic neuroblastoma to the left lateral ventricle of the brain is presented. Planar 123I-MIBG scintigraphy showed faint tracer activity close to the midline without asymmetric extensions or abnormal activity in the skull bones. A subsequent brain MR scan revealed an enhancing mass within the left frontal horn consistent with a metastatic lesion. The patient underwent tumor resection with pathology showing neuroblastoma. Our case shows that 123I-MIBG scintigraphy can be useful in detecting intraventricular

brain metastases of neuroblastoma. Although the 123I-MIBG scintigraphy has been reported to have a significantly superior sensitivity in monitoring asymptomatic patients with neuroblastoma the compared with 131I-MIBG scans, bone marrow histology, bone scan, CT, and urinary catecholamine

levels, further studies may be necessary to evaluate its sensitivity in detecting brain lesions. “
“To investigate the potential of the ultrasound-based evaluation of the optic nerve sheath in a patient with spontaneous intracranial hypotension due to cervical cerebrospinal fluid (CSF) leakage. Repeated measurements of the optic nerve sheath diameter (ONSD) using B-mode sonography were performed before treatment initiation, during medical treatment, and during a course of repeated placement of epidural blood patches. On admission, transorbital sonography revealed a decreased ONSD of 4.1 mm on the right and 4.3 mm on the left side. After 8 months of treatment with caffeine and computed tomography-guided epidural blood patches a gradual distension of the ONSD into the normal range was bilaterally observed (right: 5.2 mm; left: 5.3 mm). The ultrasound-based evaluation of the optic nerve sheath may be helpful in detecting CSF hypovolemia and for determination of treatment effects. This report should be seen as a basis for future investigations on the sonographic assessment of the optic nerve sheath in diagnosis and treatment of intracranial hypotension. “
“There have been some reports on right-to-left shunt as a cause of cryptogenic stroke.
