Wegener granulomatosis of the eustachian tube and skull base mimicking a malignant tumor.
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.
