Abstract:
Objective To investigate the imaging features of aggressive angiomyxoma.Methods CT findings in 3 patients and MRI finding among one of them with pathologically proved aggressive angiomyxoma were retrospectively analyzed and the relevant literature were reviewed.Results In all the 3 cases,CT and MR imaging demonstrated a well defined mass arising from the pelvis,perineum or vulva.The tumours displaced but did not invade adjacent structures of the pelvic.In 2 cases,there was marked enhancement following injecting contrast materials or T_2WI with internal swirling pattern.Recurrent tumour in one case was of similar imaging features to the primary lesion.The small cystiform area could be seen inside the lesion in one case.Conclusion Aggressive angiomyxoma carries certain characteristics in CT and MRI manifestations.MRI is more excellent than CT in delineating the site,shape and the extent of these lesions.
