Seven patients with meningiomas and five patients with neuromas were examined with spin-echo sequences on a 0.35-T imaging system. Signal enhancement and relaxation rate increments with gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) were evaluated, as well as relaxation rate contributions, indicators of Gd-DTPA accessibility to the tissue water. The average signal enhancement rate wit...

abstract background: invasive fungal infection is an opportunistic infection caused commonly by mucoraccae and aspergillus. it mostly occurs in patients with underlying disease. since it has a high mortality and morbidity rate, considering a treatment strategy seems necessary.   objective: since there has not been a clear protocol for treating these patients, we decided to establish a protocol ...

OBJECTIVE To review our experience of reconstructing the lateral and superior orbital walls after resection of sphenoid wing meningiomas. We will review the presentation and complications, examine the aesthetic results postoperatively, and compare preoperative and postoperative computed tomographic scans. To our knowledge, a comparative analysis of preoperative defect and postoperative reconstr...

RATIONALE Meningiomas are mostly regarded as benign tumors histologically,accounting for 13% to 26% of all primary intracranial tumors.It is testified that multiple meningiomas occur in <10% of cases.A case of concurrent grades I and II in the same patient in our hospital was described. PATIENT CONCERN A 66-year-old man who was experiencing headache and weakening in the left limbs, which grad...

D. Schulz-Ertner, C. Thilmann, M. Wannenmacher, J. Debus Before patient irradiations started in 1997, a radiation unit was built at the heavy ion synchrotron of the GSI and major future directed technical and radiobiological innovations have been implemented. For the first time, tumor conform application of carbon beams was realized by intensity-controlled rasterscanning with pulse-to-pulse ene...

OBJECTIVES/HYPOTHESIS To describe surgical outcomes and radiographic features of olfactory groove meningiomas treated by excision through the subcranial approach. Special emphasis is placed on paranasal sinus and orbit involvement. STUDY DESIGN Retrospective review of a series of patients. METHODS Nineteen patients underwent excision of olfactory groove meningioma (OGM) via the transglabell...

BACKGROUND Routine postoperative imaging (PI) following surgery for intracranial meningiomas is common practice in most neurosurgical departments. The purpose of this study was to determine the role of routine PI and its impact on clinical decision making after resection of meningioma. METHODS Patient and tumor characteristics, details of radiographic scans, symptoms and alteration of treatme...

The endoscopic endonasal transclival approach has been widely described for its use to resect clivus chordomas, but there have only been isolated reports of its use for petroclival meningiomas. These tumors are most often resected utilizing open transpetrosal approaches, but these operations, difficult even in the hands of dedicated skull base surgeons, are particularly challenging if the menin...
