Abstract:Objective: To study imaging characteristics of aggressive angiomyxoma(AAM). Methods: Ten patients(F∶M=7∶3) with preoperative imaging examinations confirmed as AAM by surgery and pathology were collected from 2012 to 2016 in our hospital and their clinical and imaging data were retrospectively analyzed. Results: In 10 cases of patients, 6 lesions occurred in the perineum and pelvis, three of which grew across the diaphragm and other incidence sites were vulva, right thigh, retroperitoneal and ileocecal junction. The maximum diameter of 9 cases of lesions was vertical diameter. In 7 cases of patients with enhanced CT examination, 3 cases showed mild enhancement and 4 cases showed significant enhancement. In 3 cases, laminated enhancement was showed. Calcification was seen in 1 case. In 6 cases of patients with MRI examination(5 cases with enhancement), 5 lesions showed high signal on T2WI. 4 cases showed significant enhancement, and laminated enhancement was seen in 3 cases. Conclusion: AAM had some clinical and imaging characteristics. For female patients of reproductive age, tumors located in perineum or crossing the pelvic diaphragm, with high signal intensity on T2WI and laminated appearance highly suggest the diagnosis of AAM.
