Central neurocytoma was first described in the literature in 1982 and has been noted to be a benign neuronal tumor usually located in the ventricular system. Of the more than 100 reported cases, only seven recurrences have been reported, all of which have been local. The authors report two cases of recurrent central neurocytoma that disseminated through the(More)
PURPOSE To evaluate by means of high-resolution CT the anatomic variations of the middle cranial fossa foramen. METHODS We examined 123 CT studies of the temporal bone in patients with no evidence of disease that might alter foraminal anatomy. A checklist of known variants and suspected structures was used as each case was systematically examined for the(More)
BACKGROUND To correlate magnetic resonance imaging (MRI) findings of non-enhancement of supratentorial brain neoplasms in adults with histopathologic findings. METHODS Forty adult patients whose preoperative MRI studies demonstrated a non-enhancing supratentorial brain neoplasm were identified retrospectively. Biopsy material for all patients was then(More)
BACKGROUND The unmatched soft tissue contrast provided by magnetic resonance imaging (MRI) has made it the modality of choice for many neuroimaging examinations. The fact that signal intensity in MRI depends on many parameters, including spin-lattice and spin-spin relaxation times, proton density, and velocity, makes it possible to highlight various(More)
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(More)
Carcinomas of the hard or soft palate are known to spread perineurally along palatine branches of the maxillary nerve. Imaging of perineural tumor spread from the palate has been underemphasized in the imaging literature. We report the findings from eight patients in whom spread from primary cancers of the palate was seen along the palatine nerves.(More)
The authors report three cases of penetrating craniocervical injury by wooden foreign bodies, which were initially hypodense on CT and thought to be air. When these structures were scrutinized with higher window settings, they had a higher attenuation and a unique striated internal architecture which the authors propose may be specific to wood.
BACKGROUND AND PURPOSE Recent work has shown that fluid-attenuated inversion recovery (FLAIR) imaging with contrast enhancement is highly sensitive for detecting subarachnoid space disease. We hypothesized that contrast-enhanced FLAIR imaging has superior sensitivity to contrast-enhanced T1-weighted MR imaging in detecting leptomeningeal metastases. (More)
