The patient had experienced acute abdominal symptoms during her last pregnancy, which were indicative of red degeneration. The uterine artery is the first or the second branch of the anterior division of the internal iliac artery (also called the hypogastric artery) in 51 % of cases, and it has several branches: the cervicovaginal artery and the arcuate arteries.

Leiomyoma with myxoid degeneration in a 55-year-old woman. When the connecting blood vessels cannot provide enough oxygen to a fibroid, its cells begin to die, or degenerate. Childbirth and Myoma Treatment by Uterine Artery Occlusion: Do They Share a Common Biology? (c) Photograph of the cut surface of the resected lesion shows an almost entirely cystic mass with scanty solid tissue. (b, c) Sagittal nonenhanced (b) and gadolinium-enhanced (c) spin-echo T1-weighted MR images (600/20) show prominent enhancement of the entire mass except for small foci of cystic changes. Hemorrhage and necrosis are not obvious. We have encountered several cases of cervical leiomyomas with an unusual growth pattern. Unusual appearances are discussed from three points of view: MR imaging–histopathologic correlation, specific types of unusual leiomyomas, and unusual growth patterns. Conventional radiograph on the left shows a large soft tissue mass (black arrows) arising from the pelvis and extending into the lower abdomen. Figure 4d. In support of this, there is the observation that large fibroids are more hypoxic than small ones [. Figure 9a. See print version. MRI for preoperative evaluation dem-onstrated a gravid uterus, with small intra-mural and subserosal fibroids. Viewer. 24, No. May show a hypoechoic or heterogeneous uterine mass with cystic areas. This report exemplifies how challenging the diagnosis could be with fibroid degeneration. 26, No. (a) Sagittal spin-echo T2-weighted MR image (2,000/70) shows a large mass of high signal intensity with scattered foci of low signal intensity arising from the uterus. It is estimated that 20-50% become symptomatic, with symptoms including abnormal uterine bleeding, pelvic pain, bowel or urinary obstruction, or pregnancy related complications [ 1 ].

Multiple uterine leiomyomas. (b) Sagittal spin-echo T1-weighted MR image (600/13) obtained several hours after onset shows no significant findings. The calcification is usually dense and amorphous. No hyalin is present. No hyalin is present. Types of degeneration include hyaline degeneration, myxoid or cystic degeneration, necrotic degeneration, red (hemorrhagic) degeneration, calcification or fatty degeneration, and sarcomatous transformation (very rarely, <0.05 % of resected fibroids) [, Sessile subserosal fibroids. The signal intensity of the mass corresponds to fluid mixed with thin, interlacing tissue of intermediate signal intensity on both images. (d) Photograph of the cut surface of the resected lesion shows a soft, yellow mass. The edema is scattered throughout the lesion in a speckled pattern but is frequently prominent at the periphery (,10) (,,,,Fig 5). 4, Journal of Computer Assisted Tomography, Vol. Submucosal and intramural fibroids may also cause infertility, spontaneous abortions, or premature placental abruption. The leiomyoma may then become attached to other pelvic structures or the omentum and be supplied by parasitic vessels (,,,Fig 13). (a) Sagittal fast spin-echo T2-weighted MR image (5,000/100) obtained several hours after onset shows a thick rim of distinct low signal intensity that corresponds to acute hemorrhage (arrows). 02, No. Smooth muscle cells are so widely separated by abundant myxoid material that mitotic count and cellularity cannot be assessed precisely. (a, b) Sagittal fast spin-echo T2-weighted (4,000/130) (a) and nonenhanced spin-echo T1-weighted (600/10) (b) MR images show a huge leiomyoma (arrows) posterior to the uterus (U).

As fibroids enlarge, they may outgrow blood supply and they may degenerate. Figure 3a. Viewer.

(b) Sagittal spin-echo T1-weighted MR image (600/13) obtained several hours after onset shows no significant findings. The necrotic areas have high signal intensity on the T1-weighted image (b) and demonstrate no enhancement on the gadolinium-enhanced image (c). (a) Sagittal spin-echo T2-weighted MR image (2,000/70) shows a large mass of high signal intensity with scattered foci of low signal intensity arising from the uterus. 46, No. The common types of degeneration are hyaline (>60% of cases), cystic (∼4%), myxoid, and red. (d) Photomicrograph (original magnification, ×200; hematoxylin-eosin stain) shows nuclear atypia. Viewer. Limitations of transvaginal ultrasound include operator-dependent variability, failure to detect small uterine fibroids, and difficulty in mapping large uteri, particularly when there are multiple fibroids. 3, The Journal of the American Association of Gynecologic Laparoscopists, Vol. (a, b) Sagittal spin-echo T1-weighted (600/25) (a) and T2-weighted (2,000/70) (b) MR images show a mass posterior to the uterus (U) (arrows).
