Individuals with congenital adrenal hyperplasia (CAH) provide a test population for the theory that elevated testosterone levels alter prenatal brain development and increase the risk of learning disabilities. Eleven subjects with CAH, five of their non-CAH siblings and 16 matched control subjects participated in two studies. The first study documented hand(More)
BACKGROUND AND PURPOSE Prior studies have revealed little difference in residents' abilities to interpret cranial CT scans. The purpose of this study was to assess the performance of radiology residents at different levels of training in the interpretation of emergency head CT images. METHODS Radiology residents prospectively interpreted 1324 consecutive(More)
BACKGROUND AND PURPOSE Benign and malignant fractures of the spine may have similar signal intensity characteristics on conventional MR imaging sequences. This study assesses whether in-phase/opposed-phase imaging of the spine can differentiate these 2 entities. METHODS Twenty-five consecutive patients who were evaluated for suspected malignancy (lymphoma(More)
BACKGROUND AND PURPOSE Collections of extraluminal paratracheal gas may be present on CT images of the neck and cervical spine and the radiologist may question whether this is related to a pathologic process. This study is designed to demonstrate the appearance, clinical presentation, and prevalence of paratracheal air cysts, which, on CT examinations of(More)
BACKGROUND AND PURPOSE Despite improvements in noninvasive imaging, some patients with contraindications to iodine-based contrast material still require angiography for the evaluation of carotid stenosis. Our aim was to assess the utility of gadopentetate dimeglumine as an intraarterial contrast agent in common carotid angiography. METHODS Twelve patients(More)
INTRODUCTION Solitary brain metastasis (MET) and glioblastoma multiforme (GBM) can appear similar on conventional MRI. The purpose of this study was to identify magnetic resonance (MR) perfusion and diffusion-weighted biomarkers that can differentiate MET from GBM. METHODS In this retrospective study, patients were included if they met the following(More)
Bullet embolism is a rare phenomenon following gunshot injuries. We present a case of a 25-year-old male who sustained a gunshot wound to his left globe with the bullet initially lodged in his right transverse sinus. The bullet ultimately embolized to a left lower lobe pulmonary artery resulting in a pulmonary infarct. A discussion of select prior cases,(More)
We describe two cases of disseminated coccidioidomycosis that were complicated by fatal subarachnoid hemorrhage. In the first case, a left middle cerebral artery aneurysm and long-segment vasculitis occurred. In the second case, MR imaging revealed an enlarging coccidioidal granuloma at the tip of the basilar artery, and the artery subsequently ruptured.(More)
BACKGROUND AND PURPOSE Our purpose was to describe the MR imaging findings in patients with acute coccidioidal meningitis. METHODS Fourteen patients (11 men, three women; 22-78 years old; mean age, 47 years) with coccidioidal meningitis underwent neuroimaging within 2 months of diagnosis. Thirteen patients had MR imaging and one had an initial CT study(More)
In three patients with histiocytosis X of bone with orbital involvement, CT scans were reviewed. Consistent findings included a destructive lesion of the lateral wall of the orbit with a large soft-tissue component that extended into the extraconal space, the ocular adnexa, and the infratemporal fossa. The greater wing of the sphenoid was eroded in all(More)
