MORNING TO Y’all from Mayo Mwiche Medical Imaging Centre
Today we look at FIBROIDS
FIBROIDS ARE OF DIFFERENT TYPES NAMELY INTRA-CAVITARY, INTRA- MURAL, SUBMUCOSAL, SUBSEROSAL, PENDUCULATED AND MORE
Uterine fibroids, also known as leiomyomas or myomas, are the commonest uterine neoplasms. They are benign tumors of smooth muscle origin, with varying amounts of fibrous connective tissue.
Fibroids usually arise in the myometrium but may occasionally be found in the cervix, broad ligament or ovaries. They are multiple in up to 84% of women. Fibroids have been reported to occur in up to 70% of women by the age of 50 years[4] and are especially common in black women, who also often have more severe disease. These benign tumors are hormone dependent, responding to both estrogen and progesterone. they often increase in size during pregnancy and usually decrease in size after menopause. Early age at menarche and obesity are risk factors for the development of fibroids, likely due to the increased exposure to estrogen.
Definition:
Uterine fibroids, also known as leiomyomas, are the commonest uterine neoplasms. Although benign, they can be associated with significant morbidity and are the commonest indication for hysterectomy. They are often discovered incidentally when performing imaging for other reasons.
Classification and histopathological features.
Uterine fibroids are classified according to their location as submucosal, intramural or subserosal.Submucosal fibroids are the least common type, accounting for just 5% of all fibroids, [8] but they are the most likely to be symptomatic since they project into the endometrial cavity.
Submucosal fibroids can occasionally become pedunculated and prolapse into the cervical canal or va**na. Intramural fibroids [are the most common type, but they are usually asymptomatic; however, they may cause infertility due to compression of the fallopian tubes.
Subserosal fibroids, project exophytically into the abdomen or pelvis and can also become pedunculated, which may be confused with ovarian tumors. Pedunculated subserosal fibroids can undergo torsion and consequent infarction and thus be a cause of severe abdominal pain. Large fibroids often degenerate as they outgrow their blood supply. The various types of degeneration include hyaline, myxoid,
