FD American Society of Neuroradiology SP 1785 OP 1790 VO 17 IS 9 A1 R C Helmberger A1 A A Mancuso YR 1996 UL http://www.ajnr.org/content/17/9/1785.abstract AB Wegener granulomatosis is a well-studied yet sometimes difficult-to-diagnose systemic vasculitis. Early treatment with immunosuppressants is the therapy of choice and usually controls the disease. Two cases of Wegener granulomatosis are presented, both with symptoms and imaging findings suggestive of a malignant tumor of the nasopharynx or skull base. The focus of upper respiratory involvement in each case was the eustachian tube.
