The MR imaging and spectroscopy

performed on a 1.5-tesla scanner in three female patients revealed T1 hyperintense mass lesions. A large dominant metabolite peak at 2.0-ppm chemical shift, simulating N-acetylaspartate (NAA) of normal neuronal tissue was detected within the lesion. This peak is probably due to the presence of glycoproteins secreted by the ciliated columnar epithelium lining these cysts. MR spectroscopy of colloid cyst has not been described in the literature and hence the findings in this study will help in the diagnosis of this cystic lesion especially when located at unusual location. The signal characteristics of these cysts in various sequences including diffusion weighted imaging (DWI) and AZD5363 supplier susceptibility weighted imaging (SWI) are also discussed.”
“Survival rates have greatly improved in recent years for infants of borderline viability;

however, these infants remain at risk of developing selleck kinase inhibitor a wide array of complications, not only in the neonatal unit, but also in the long term. Morbidity is inversely related to gestational age; however, there is no gestational age, including term, that is wholly exempt. Neurodevelopmental disabilities and recurrent health problems take a toll in early childhood. Subsequently hidden disabilities such as school difficulties and behavioural problems become apparent and persist into adolescence. Reassuringly, however, most children born very preterm adjust remarkably well during their transition into adulthood. Because mortality rates have fallen, the focus for perinatal interventions is to develop strategies to reduce long-term morbidity, especially the prevention of brain injury and abnormal brain development. In addition, follow-up to middle age and beyond is warranted to identify the risks, especially for cardiovascular and metabolic disorders that are likely to be experienced by preterm survivors.”
“Introduction

Spinal cord tumors (SCT) are best treated by surgery. Vascular SCT (VSCT) represent a special challenge because of the bleeding that may occur during Ixazomib purchase surgery and the subsequent difficulties in operating on these lesions. Embolization has been proposed as an approach that would facilitate VSCT resection.

Methods The clinical and radiological charts of five patients, each with a large solid VSCT (four cervical hemangiobastomas, one filum terminale paraganglioma), were retrospectively reviewed. All of these hypervascular lesions were superselectively embolized prior to surgery (four with N-butyl cyanoacylate (glue), one with particles).

Results Intranidal deposition of the glue was successful in all four patients, resulting in significant devascularization of the tumor. Because of arterial tortuosities, it was not possible to reach distally a cervical hemangioblastoma, and the latter was consequently embolized with particles.
