Liquefaction of fibroids on uterine ultrasound may be associated with cystic degeneration of the fibroids, and the exact diagnosis needs to be determined by biopsy. Uterine fibroids are originally solid tumors, but as the tumor continues to grow, there may be ischemic necrosis within the fibroid, and the necrotic cells produce blood and water and become encapsulated within the fibroid, which manifests itself on ultrasound as fibroid liquefaction. Uterine fibroids are mostly benign tumors, which may have pathological changes such as liquefaction, calcification, red-like changes, malignant changes, etc. Liquefaction is a kind of degeneration of uterine fibroids, which is often accompanied by abdominal pain, fever and other symptoms. When uterine fibroid degeneration occurs, it is necessary to perform surgery for treatment, and pathological examination should be done after surgery to exclude the possibility of malignant changes. Pay attention to rest on weekdays, under the guidance of the doctor treatment.
