Analysis of cystic intracranial lesions performed with fluid-attenuated inversion recovery MR imaging.
BACKGROUND AND PURPOSE T1-, T2-, and proton density (PD)-weighted sequences are used to characterize the content of cystic intracranial lesions. Fluid-attenuated inversion recovery (FLAIR) MR sequences produce T2-weighted images with water signal saturation. Therefore, we attempted to verify whether FLAIR, as compared with conventional techniques, improves the distinction between intracranial c...
متن کاملSpontaneous cerebrospinal fluid leakage through fistulas at the clivus repaired with endoscopic endonasal approach
Background: Causes of cerebrospinal fluid (CSF) leakage are primarily traumatic or iatrogenic in origin. In contrast, spontaneous CSF leakage is somewhat rare, and detection of the fistula can be challenging. Meningitis associated with CSF leakage can be life threatening. It is therefore critical to surgically repair the fistula once the underlying cause has been accurately identified. Spontane...
متن کاملNeuroradiologic-pathologic correlation in a neurenteric cyst of the clivus.
A 28-year-old woman presented with left-sided frontotemporal headache lasting 6 wk. Head CT and MR imaging revealed a clival mass, which was interpreted as a chondrosarcoma. The lesion was removed at endoscopic endonasal surgery; histologic and immunohistochemical findings proved it to be neurenteric cyst. On CT scans, the lesion was lytic, with an intact cortex; it was uniformly hyperintense r...
متن کاملMagnetic Resonance Imaging of the Clivus and Its Age-Related Changes in the Bone Marrow
BACKGROUND The clivus is a bone region between dorsum cella and foramen magnum. It can be evaluated very clearly in routine brain magnetic resonance imaging (MRI) dueto its central location. OBJECTIVES Quantitative and qualitative evaluation of the clivus and its changes according to age in a group of healthy people. PATIENTS AND METHODS The transition of clival bone marrow to fatty marrow ...
متن کاملPrimary spontaneous cerebrospinal fluid leaks located at the clivus
Transclival meningoceles and primary spontaneous cerebrospinal fluid (CSF) leaks at the clivus are extremely rare lesions and only few of them have been reported in the literature. We report here six cases of transclival primary spontaneous CSF leaks through the clivus. A retrospective case study was performed. We reviewed six cases involving sinonasal CSF leaks located at the clivus treated be...
