BACKGROUND Recent studies suggest aggressive management combining a grossly total resection (GTR) with adjuvant radiotherapy (RT) as a treatment of choice for intracranial hemangiopericytoma (HPC). However, in these papers, the definitions of complete or GTR are equivocal. In the present study, we reviewed the relevant cases from our experience focused on the clinical efficacy of surgical gradi...

BACKGROUND Unilateral adult thalamic gliomas are rarely reported. In this study, the authors aimed to analyze the clinical, radiological, and pathological features of adult primary unilateral thalamus gliomas (UTGs). METHODS Clinical data of 33 UTGs in adults who underwent surgical treatment between 2005 and 2014 at the Beijing Tiantan Hospital were collected and retrospectively studied. Foll...

Background: Transcranial approaches were historically the first established routes for craniopharyngiomas resection. Transcranial approaches commonly entail some degree of brain retraction as well as manipulation of neurovascular structures, located between the surgeon and the pathogenic region. A more direct route to the sellar -suprasellar region is provided by the transsphenoidal approach. I...

BACKGROUND AND PURPOSE To improve the resection rate of unexpected residual pituitary tumor under image guidance, iCT provides a less time-consuming and more convenient approach of promising the safety of the trans-sphenoidal surgery. However, iCT was thought to have worse image quality than MR imaging. This study was designed to determine the predictive concordance of iCT with standard postope...

OBJECT Atypical (WHO Grade II) meningiomas comprise a heterogeneous group of tumors, with histopathology delineated under the guidance of the WHO and a spectrum of clinical outcomes. The role of postoperative radiotherapy for patients with atypical meningiomas who have undergone gross-total resection (GTR) remains unclear. In this paper, the authors sought to clarify this role by reviewing thei...

Background: Patients with thoracic neuroblastoma (TNB) are at high risk of postoperative neurologic complications due to iatrogenic lesions the artery Adamkiewicz (AKA). The role performing a preoperative spinal angiography (POSA) in these patients must be clarified. present study sought further understand relationship between POSA and TNB, as well effects identifying AKA on surgical excision n...

When granulocytes are labeled with diisopropyl-fluorophosphate (DFP32) and then returned to the circulation of the donor, the labeled granulocytes are distributed in a pool of cells which is approximately two times larger than that calculated from the blood volume and the concentration of granu-locytes in the circulating venous blood (1, 2). This pool has been referred to as the total blood gra...

OBJECT Low-grade glial and glioneuronal brain tumors are frequently encountered in the pediatric population and can be effectively treated by resection. The authors aimed to use imaging to evaluate how often tumors recurred and to determine if recurrences were associated with any clinical symptoms, along with the financial costs of imaging, in patients with radiographically proven gross-total r...
