Abstract:
:A systematic approach to the diagnosis and treatment of angiofibromas is presented. The distinction between true and false internal carotid supply to these tumors as well as identification of vascular anatomical variants that may represent potential hazards of embolization are emphasized. Areterial supply to the cranial nerves, prevention of neurologic complications, and the use of inappropriate embolization materials are also discussed.

RADIOLOGY文献大全abstract::The CT findings in two surgically proved cases of spontaneous chronic extradural hematoma are presented. Tapered convex margins, a length greater than 2 cm, and associated normal intervertebral disks are findings that help distinguish chronic extradural hematoma from an extruded disk. ...
