... This phenomenon coupled with occlusion of the primary blood source creates a parasitic myoma. 2 Intramural myomas protruding into the areolar tissue between the leaves of the broad ligament are referred to as intraligamentous or parametrial myomas. 3 There is a decided propensitx of fibroids to outgrow their hlood supply and undergo various types of degenerative changes. ...

This ten-year study of the massive fibroid at the Queen of Angels Hospital will reveal an average of 66 cases per year which could be classified as large and massive. Only about ten cases per year qualify as massive (four gestational months or larger). There were none considered giant size (25 lbs or more).The literature is replete with these, one of which (weighing 100.2 lbs) will be reported in detail. The mortality rate continues to be considerable in these (14.8 to 16.7 percent). In the smaller tumors, mortality is rare and morbidity is minimal.Bleeding, pain, and pressure symptoms, due to impingement on neighboring organs, are the principal symptoms. Sarcomatous change, fortunately, still remains quite rare.Treatment usually involves a pre-operative dilatation and curettage when bleeding is a problem, followed by total abdominal hysterectomy and bilateral salpingo-oophorectomy where indicated. Appendectomy is usually incidental. Anesthesia is usually spinal, if not otherwise contraindicated.Ultrasound is a new and refined diagnostic tool.

Because fibroids have so many sonographic appearances, they can mimic numerous pelvic conditions. Awareness of these potential problems, especially in the presence of other fibroids, may be helpful in making the correct diagnosis. Proper identification of the uterus, close analysis of its echo texture and cavity echoes, and attention to good sonographic technique will improve diagnostic accuracy and thereby improve patient care.

Sound is a mechanical vibration of particles in a medium around an equilibrium position. Sonic waves require a medium of a molecular nature in order to propagate. The highest frequency sound audible to the human ear is 20,000 cycles per second or 20 kiloHertz (kHz). Sound waves above this frequency are described as ultrasound. Unlike electromagnetic waves, sound cannot travel across a vacuum (9).

Diagnostic B scan ultrasound and urography are not competitive, but complementary diagnostic modalities for the diagnosis of renal masses in children. As illustrated in the case presentations, differential diagnostic features of congenital hydronephrosis, congenital multicystic disease, obstructive uropathy, Wilms' tumor, and obstructive vascular disease of the kidneys are most accurate when both modalities are utilized.
