Intermural fibroids generally grow slowly, depending on the individual, and if they grow too quickly the fibroid may have degenerated. Intermural fibroids are a type of uterine fibroids, which are fibroids that grow between the walls of the uterine muscle and are surrounded by the muscle layer. Uterine fibroids usually grow slowly and most of them have no obvious symptoms. If the size of intermural fibroids is large, there may be increased menstrual flow, prolonged menstrual period, increased leukorrhea, and some of them may be palpable lumps in the abdominal wall. If the intermural leiomyoma grows too fast, it may be red leiomyoma, leiomyosarcoma, etc., and it is necessary to take leiomyomectomy or hysterectomy according to the condition of the disease to clarify the nature of the lesion. It is recommended to consult a doctor promptly for standardized diagnosis and treatment in case of rapid growth of intermural leiomyoma.
