A patient with an intracranial dermoid tumor that ruptured secondary to closed head trauma is described. Intracranial dermoid tumors (cysts) have been reported to rupture spontaneously during or following surgery. To the authors' knowledge, rupture of a dermoid cyst following closed head trauma has not been reported.
Computer-assisted diagnostic systems enhance the information available from magnetic resonance imaging. Segmentations are the basis on which three-dimensional volume renderings are made. The application of a raw data-based, operator-independent (automatic), magnetic resonance segmentation technique for tissue differentiation is demonstrated. Segmentation… (More)
Due to the combined increase in circuit integration and chip power dissipation, there is a rapidly growing demand for solving the thermal management issues of power microelectronics. We are pursuing a novel thermal management approach that actively cools only the key high power devices by using a novel thermoelectric microcooler located under each of these… (More)
This report describes a paciniomyolipoma as an intradural tumor of the lumbar spinal cord composed of adipose tissue, striated skeletal muscle, and pacinian corpuscles. Simple lipomas, myolipomas, and other variant lipomas of the spinal cord have been described in the literature; to the authors' knowledge, however, this is the first report of this unusual… (More)
Neuroradiologists performing cervical spine MR scans are reminded that an aberrant right subclavian artery is detectable on sagittal cervical spine views. This review of 335 consecutive patients revealed two such anomalies for a prevalence of 0.6%, which compares favorably with the published range of occurrences in the literature (0.5 to 2%).
