OBJECTIVE To study the clinical characteristics and treatment of meningiomas in children. METHODS One hundred and sixty-six meningiomas in children, including 12 cases treated in Qilu hospital and 8 series reported in the literature, were analyzed retrospectively on sex, age distribution, presenting symptoms, signs, radiological and pathological findings,(More)
In order to study the clinical characteristics of intraventricular meningiomas, we analyzed retrospectively 25 patients and reviewed the literature with regard to incidence, clinical manifestation, imaging features, preoperative diagnosis, surgical findings, and histopathological results. Intraventricular meningiomas are quite rare, but they represent an(More)
To study the clinical characteristics of tuberculum sellae meningiomas, we retrospectively analyzed 43 patients and reviewed the literature with regard to the incidence, clinical manifestations, imaging features, microsurgical anatomy, and postoperative outcomes of tuberculum sellae meningiomas, and the technical aspects of their treatment. CT or MRI(More)
This study aims to achieve the complete removal of trigeminal schwannoma (TS) while preserving cranial nerve function. We focused on the outcomes of different surgical approaches and address the contributions of different operative techniques. Forty-two TS cases, treated surgically in Qilu Hospital during a 12-year period, were reviewed and analyzed. There(More)
To study the clinical characteristics of cystic meningiomas, we analyzed retrospectively 21 patients with cystic meningiomas and reviewed the literature with regard to clinical presentation, imaging features, preoperative diagnosis, surgical findings, and histopathological results. The cysts were classified into intratumoral and peritumoral cysts based on(More)
Neovascularization plays a substantial role in the regulation of invasion of glioblastoma. However, the underlying molecular basis remains largely unknown. Both vascular endothelial growth factor a (VEGFa) and matrix metalloproteinases 2 (MMP2) are essential for cancer neovascularization and cancer invasion in that they promote endothelial mitogenesis and(More)
AIM To evaluate the effectiveness of microvascular-decompression (MVD) or MVD+partial-sensory-rhizotomy (PSR) on the treatment of primary trigeminal neuralgia (TN). MATERIAL AND METHODS 210 TN patients were retrospectively studied, among which there're 142 cases underwent MVD and 68 cases underwent MVD+PSR. RESULTS In MVD group, pain(More)
Malignant (anaplastic) meningioma constitutes a rare subset of meningioma. The aim of the study was to study clinical features and management of malignant meningiomas. Twenty-two patients with malignant meningiomas were surgically treated in our department between January 1986 and January 2005 in Qilu hospital, and we reviewed each patient's clinical(More)
Microvascular decompression (MVD) is now a standard treatment for trigeminal neuralgia (tic douloureux). The goal of MVD is to decompress the trigeminal root from offending vessels, aiming at a permanent cure with no or little sensory deficit. Preoperative identification of neurovascular compression, therefore, has potentially important implications for(More)
Cerebral metastasis rarely occurs in paraganglioma. We report the first patient, to our knowledge, with both skull and brain metastases, who underwent abdominal and skull, as well as brain lesion resection over 5 years, with a satisfactory outcome at the 10-year follow-up. We describe the characteristics and explore the possible underlying mechanisms to(More)
