Emergency decompressive craniectomy after removal of convexity meningiomas
BACKGROUND Convexity meningiomas are benign brain tumors that are amenable to complete surgical resection and are associated with a low complication rate. The aim of this study was to identify factors that result in acute postoperative neurological worsening after the removal of convexity meningiomas. METHODS Clinical evaluation and neuroradiological analysis of patients who underwent removal...
متن کاملTwo supratentorial meningiomas: are they different?
DESCRIPTION A 65-year-old woman comes for headache management. Few years ago, she was diagnosed with a ‘single benign tumour of the anterior part of the brain’. A new contrast CT brain scan was done (figures 1 and 2); as she was claustrophobic, brain MRI was not ordered. The mass they have referred to was most likely a falcine meningioma. In addition, there is an oval hyperdense mass at the rig...
متن کاملPredictors of peritumoral edema after stereotactic radiosurgery of supratentorial meningiomas.
OBJECTIVE Anecdotal evidence suggests that radiosurgical ablation of parasagittal meningiomas may be associated with increased risk of subsequent edema. Potential predictors of postradiosurgical peritumoral edema, including parasagittal tumor location, tumor size, and treatment dose, were evaluated. METHODS We retrospectively reviewed records of 102 patients with 111 supratentorial meningioma...
متن کاملExperience with 7.0 T MRI in Patients with Supratentorial Meningiomas
Meningiomas are typically diagnosed by their characteristic appearance on conventional magnetic resonance imaging (MRI). However, detailed image findings regarding peri- and intra-tumoral anatomical structures, tumor consistency and vascularity are very important in pre-surgical planning and surgical outcomes. At the 7.0 T MRI achieving ultra-high resolution, it could be possible to obtain more...
متن کاملDistinguishing grade I meningioma from higher grade meningiomas without biopsy
BACKGROUND Many meningiomas are identified by imaging and followed, with an assumption that they are WHO Grade I tumors. The purpose of our investigation is to find clinical or imaging predictors of WHO Grade II/III tumors to distinguish them from Grade I meningiomas. METHODS Patients with a pathologic diagnosis of meningioma from 2002-2009 were included if they had pre-operative MRI studies ...
