They are clinically apparent in ~25% of women of reproductive age and over 70% of women by menopause 21. Fibroids are responsive to hormones (e.g. stimulated by estrogens). Being rare in prepubertal females, they commonly accelerate in growth during pregnancy and involute with menopause 1. 1. 2-3x increased incidence in Black women than in White wo...
They are often asymptomatic and discovered incidentally. Signs and symptoms associated with fibroids include: 1. abnormal vaginal bleeding 2. pain 3. infertility 4. palpable masses
Leiomyomas are benign monoclonal tumors 16 predominantly composed of smooth muscle cells with variable amounts of fibrous connective tissue. They are commonly multiple (~85% 8), and range significantly in size. Any fibroid may undergo atrophy, internal hemorrhage, fibrosis, and calcification. They can also undergo several types of degeneration: 1. ...
Popcorn calcificationwithin the pelvis may suggest the diagnosis. Ultrasound is used to diagnose the presence and monitor the growth of fibroids: 1. uncomplicated leiomyomas are usually hypoechoic, but can be isoechoic, or even hyperechoic compared to normal myometrium 2. calcification is seen as echogenic foci with shadowing 3. cystic areas of nec...
There are various medical, surgical, and interventional treatment options: 1. myomectomy: recurrence rate of 40-55% at 5 years 23 2. focal endometrial curettage 3. hormone administration 4. hysterectomy 5. uterine artery embolization (UAE) 6. high-intensity focussed ultrasound (HIFU) 1. invasion of adjacent venous channels leading to intravenous le...
General imaging differential considerations include: 1. uterine leiomyosarcoma 1.1. malignant transformation into leiomyosarcoma is rare. 1.2. unfortunately, no imaging modality can reliably differentiate a benign leiomyoma from the rare leiomyosarcoma 2. uterine smooth muscle tumors of uncertain malignant potential: rare 3. uterine lipoleiomyoma: ...
15 de jun. de 2021 · Los miomas subserosos se dividen en los tipos 5, 6 y 7 de la FIGO en función de la extensión intramural: Si presentan un componente >50% intramural y <50% subseroso son tipo 5. Mientras que si presentan un componente intramural <50% y subseroso >50% son de tipo 6.
Los miomas uterinos son los tumores mesenquimaticos más frecuentes del útero y resultan de una mutación somática de una célula de músculo liso y la posterior expansión clonal de estas células.

El sistema de clasificación de la International Federation of Gynecology and Obstetrics (FIGO) para las causas de sangrado uterino anormal (Sistema PALM-COEIN) tiene una subclasificación para la localización de los miomas y el grado en que protruyen en la cavidad endometrial (3).
Los miomas pueden ser clasificados por su localización. La Federación Internacional de Ginecólogos y Obstetras (FIGO) propone la siguiente clasificación: - Mioma submucoso (FIGO tipo 0,1,2): Derivan de las células miometriales subyacentes al endometrio, de forma que protruyen en la cavidad endometrial.
En mujeres no embarazadas, los miomas suelen ser asintomáticos. Los dos síntomas más frecuentes de leiomiomas uterinos por los que las pacientes buscan tratamiento son la hemorragia uterina anormal y la sensación de presión pélvica. Algunas veces se produce degeneración, que causa dolor intenso.
