RT Journal Article SR Electronic T1 Benign osteoblastoma of the temporal bone. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 324 OP 326 VO 18 IS 2 A1 M Ohkawa A1 N Fujiwara A1 M Tanabe A1 H Takashima A1 K Satoh A1 Y Mori A1 Y Honjo A1 S Nagao YR 1997 UL http://www.ajnr.org/content/18/2/324.abstract AB We report a case of benign osteoblastoma arising in the temporal bone of a 28-year-old woman. Plain radiography showed a mass with an amorphous calcified matrix and a thin radiolucent marginal zone. CT and MR imaging were useful in delineating the extent of the tumor, and angiography showed its hypervascularity. Preoperative transarterial embolization was effective in reducing bleeding during surgery.
