The Teaching Point

Aggressive angiomyxoma typically presents as an hourglass-shaped, pelvic soft tissue mass that is hyperintense to muscle on T2-weighted and isointense on T1-weighted images. After administration of intravenous contrast medium it shows a strong enhancement with swirled central strands of hypointense tissue.

Abstract
Aggressive angiomyxoma is a rare soft-tissue tumor which usually occurs in female patients of reproductive age. Its occurrence in men is even more unusual and as illustrated in this case the difference between pathology suggested by a physical examination and its actual extent can be quite striking. We present a case report of an 81-year-old man with the typical MRI appearances of a pelvic aggressive angiomyxoma, describe imaging and histopathologic features of this rarely seen locally infiltrative neoplasm and also discuss therapeutic options for patients with an aggressive angiomyxoma.
