OBJECTIVE Metaplastic meningioma is a rare subtype of benign meningiomas, classified as WHO grade I with well prognosis. Here we presented our experiences on 15 cases of metaplastic meningioma, to investigate the clinicopathological features, therapies and prognosis of these cases. METHODS 15 patients underwent surgical treatment for intracranial(More)
Solitary intracranial plasmacytomas (SICPs) are extremely uncommon tumors in the central nervous system, and are often misdiagnosed pre-operatively. We report a patient with SICP, describe the neuroradiological and neurosurgical features and the clinical management of this patient, and review the pertinent literature.
BACKGROUND Rhabdoid meningioma (RM) is a rare subtype of meningioma, classified as World Health Organization grade III with a poor prognosis. Here we present our experience on RM and review relevant literature in an attempt to investigate the clinical features, treatment, and prognosis of these tumors. METHODS Twelve patients underwent surgical treatment(More)
OBJECTIVE To discuss the clinical characteristics, radiological features, surgical treatment and prognosis of sporadic meningioangiomatosis (MA). METHODS We retrospectively analyzed the medical records of ten histopathologically confirmed MA patients who were treated in the Department of Neurosurgery of Huashan hospital from 2002 to 2011. All of the(More)
OBJECTIVE To investigate the diagnosis and surgical techniques of intramedullary hemangioblastoma of the cervical spinal cord. METHODS MR imaging and the methods and results of surgery were analyzed in 21 patients. RESULTS The tumors were divided into three types on MR imaging. Syringeal type, where the tumor varied in size and was accompanied by(More)
Hemangioblastomas are extremely rare in supratentorial locations, and to date, approximately 128 cases of supratentorial hemangioblastoma have been reported in the literature. Here, we report a female case of supratentorial hemangioblastoma, not associated with von Hippel-Lindau disease. We describe its clinical, neuropathological, and neuroradiological(More)
Ectopic pituitary adenomas (EPAs) are rare tumors that most often occur in the sphenoid sinus or suprasellar region. We describe a 66-year-old man who presented with unilateral proptosis and an ipsilateral abduction deficit caused by an EPA in the spheno-orbital region. The tumor was completely excised with elimination of proptosis and restoration of full(More)
Pituitary adenoma is one of the most common intracranial neoplasms, and its genetic basis remains largely unknown. To identify genetic susceptibility loci for sporadic pituitary adenoma, we performed a three-stage genome-wide association study (GWAS) in the Han Chinese population. We first analyzed genome-wide SNP data in 771 pituitary adenoma cases and(More)
Gangliocytomas occurring in the sellar region are extremely rare. We examined a cohort of these tumors to examine their clinical presentations and prognoses. Between January 2000 and December 2012, 23 patients were diagnosed with sellar region gangliocytomas in Huashan Hospital. These patients were retrospectively reviewed for medical histories,(More)
Runoff sources and dominant flow paths are still poorly understood in most catchments. Consequently, isotope hydrograph separation methods are widely used to improve our understanding about runoff generation. Isotope hydrograph separation (IHS) is based on the mass balance equation of water flux and isotope tracer concentration. The isotope analysis machine(More)
