WEGENER GRANULOMATOSIS OF THE EUSTACHIAN-TUBE AND SKULL BASE MIMICKING A MALIGNANT-TUMOR

Wegener granulomatosis is a well-studied yet sometimes difficult-to-di agnose 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 f indings suggestive of a malignant tumor of the nasopharynx or skull ba se. The focus of upper respiratory involvement in each case was the eu stachian tube.
