Invasive angiomyxoma diagnosed by transvaginal ultrasound: a case report.

Aggressive angiomyxoma (AAM) is rare. AAM is characterized by invasion and recurrence. Improving the detection rate of AAM through ultrasonic inspection technology. There is very little literature reported on AAM. And the literature on the ultrasonic performance of AAM is rare. Therefore, this article describes the ultrasound manifestation of a 54-year-old woman whose pathology is confirmed to be AAM, and summarizes the common ultrasound manifestations of AAM. The unique feature is that the ultrasound performance does not explore the typical "vortex". So we need to diagnose this case through other ultrasound findings. The patient initially had no obvious cause of pain in the right hip. Transvaginal ultrasound examination of the pelvic was performed on the patient, and pathological sections were examined. The result suggested mesenchymal tumor. After surgical resection of the tumor, the pathology was again confirmed as AAM. The tumor is composed of well-differentiated spindle-shaped stellate cells with interstitial mucus degeneration, and vascular proliferation can be seen, which is consistent with deep AAM. Through this case we found that pathology is the gold standard for AAM, but early screening of AAM by ultrasound is feasible.
