PURPOSE In this article, biochemical markers in the synovial fluid (SF) for detecting intraarticular inflammation and early cartilage degradation of the temporomandibular joint (TMJ) disease were examined. PATIENTS AND METHODS SF was obtained from 25 TMJs in 22 patients with internal derangement (ID) or osteoarthritis (TMJ-OA), 15 asymptomatic TMJs in 11(More)
The authors report the case of a 4-year-old boy who developed progressive unilateral weakness and developmental delays prior to his diagnosis of classical homocystinuria. Magnetic resonance imaging (MRI) of the brain demonstrated diffuse white matter changes, raising the concern for a secondary diagnosis causing leukoencephalopathy, since classical(More)
PURPOSE To evaluate the imaging findings, possible pathogenesis, and frequency of hemorrhage near the tentorial surface of the cerebellum after supratentorial surgery. METHODS Over a 5-year period, 13 patients with posterior fossa hemorrhage after supratentorial surgery were identified with postoperative CT studies, which were obtained in all patients(More)
OBJECT The goal of this study was to evaluate the effectiveness and limitations of gamma knife surgery (GKS) in the treatment of intracranial breast carcinoma lesions. METHODS A retrospective analysis of the GKS database at the University of Virginia Health System identified 43 patients with a total of 84 lesions who were treated between 1989 and 2000.(More)
The authors report the case of a 2-year-old boy with a primary, diffuse leptomeningeal oligodendroglioma in which the deletion of chromosome arm lp was identified by performing a fluorescence in situ hybridization (FISH) analysis. This previously healthy child initially presented with malaise, anorexia, nausea, vomiting, and macrocephaly. Imaging studies(More)
OBJECTIVES A depth of lesion (DOL) model using brain imaging has been proposed to aid in medical decision-making and planning for rehabilitation resource needs. The purpose of this study was to determine the early prognostic value of a DOL classification system for children and young adults following severe traumatic brain injury. METHODS AND OUTCOME(More)
The typical imaging findings of neonatal non-ketotic hyperglycinemia have rarely been described in the radiologic literature with only few individual cases or small series reported. In this article, we present a case of neonatal onset non-ketotic hyperglycinemia, imaged at 6 days of age, and discuss characteristic MRI and MR spectroscopic findings.
A 14-year-old boy presented with a presumed diagnosis of autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). The neurological examination, nerve conduction study, and brain imaging results were all consistent with the diagnosis. The ophthalmologic examination was notable for a prominent myelinated nerve fiber layer extending from the disk(More)
PURPOSE We evaluated the efficacy of direct hemoperfusion (DHP) for treatment of acute valproate (VPA) intoxication and speculate on the biochemical perturbations that suggest a mechanism of coma induced by VPA overdose. PATIENT AND METHODS The comatose patient was hospitalized approximately 6 h after ingesting 18 g VPA. DHP, with 200 g activated(More)
