The skull base in oncologic imaging
Radiologists are often called upon to solve diagnostic problems involving the skull base in cancer patients. This presentation focuses on three issues: the detection of osseous involvement by infiltrating neoplasms, the diagnostic approach to bone tumours and the demonstration of head and neck tumours showing intracranial spread.
متن کاملimaging of anterior skull base pathologies
several lesions (inflammatory, neoplastic and congenital) can involve in the skull base. the role of imaging is to detect the location and extension of lesion, determine mass and mass like lesions, differentiate benign from malignant tumors, detect invasion to adjacent structures and make decision in surgical planning. skull base divides to anterior, middle and posterior cranial fossa and some ...
متن کاملImaging of mucormycosis skull base osteomyelitis.
Skull base osteomyelitis (SBO) is typically bacterial in origin and caused by Pseudomonas, although the fungus Aspergillus has also rarely been implicated. SBO generally arises from ear infections and infrequently complicates sinonasal infection. Rhinocerebral Mucor infection is characteristically an acute, fulminant, and deadly infection also affecting the orbits and deep face and is associate...
متن کاملAdvances in Magnetic Resonance Imaging of the Skull Base
Introduction Over the past 20 years, magnetic resonance imaging (MRI) has advanced due to new techniques involving increased magnetic field strength and developments in coils and pulse sequences. These advances allow increased opportunity to delineate the complex skull base anatomy and may guide the diagnosis and treatment of the myriad of pathologies that can affect the skull base. Objectives ...
متن کاملDiffusion MR imaging features of skull base osteomyelitis compared with skull base malignancy.
BACKGROUND AND PURPOSE SBO is a life-threatening infection that may have radiologic features similar to those of the neoplastic processes. The purpose of this study was to evaluate the DWI findings in SBO to facilitate the differential diagnosis. MATERIALS AND METHODS The MR imaging findings of 9 patients with SBO were retrospectively evaluated and compared with MR imaging studies from 9 pati...
