What is the ovarian vascular pedicle?
The ovarian vascular pedicle sign can be defined when the gonadal veins directly join the pelvic mass. In our study, the ovarian vascular pedicle sign was identified in 92% (99/108) of the ovarian masses and in 13% (3/23) of the sub- serosal uterine myomas.
What is torsion of ovary and ovarian pedicle?
Ovarian torsion involves torsion of the ovarian tissue on its pedicle leading to reduced venous return, stromal edema, internal hemorrhage, and infarction with the subsequent sequelae. Ovarian torsion classically occurs unilaterally in a pathologically enlarged ovary.
What are the most common pelvic tumors?
Uterine Neoplasms
- The most common endometrioid tumor of the uterus—and the most common cancer of the female genital tract—is endometrial cancer.
- The most common uterine neoplasm—and the most common smooth muscle tumor of the uterus—is leiomyoma.
- Like leiomyomas, endometrial stromal sarcomas are mesenchymal tumors.
Can ovarian torsion happen after hysterectomy?
Ovarian torsion after hysterectomy is a rare event with a prevalence of 7.91/1000 hysterectomies [2]. Although hysterectomy is not a risk factor for ovarian torsion [1], it has been estimated that approximately 8% of adnexal torsions occur in patients with previous hysterectomy [3, 4].
What causes ovarian cysts to rupture?
Many ovarian cysts do not rupture. Experts don’t know why some cysts break open and some do not. A cyst is more likely to rupture during strenuous exercise or sexual activity. If you have a health condition that makes you bleed easily, you will likely need surgery for a ruptured cyst.
Does ovarian torsion show on CT scan?
An enlarged ovary with or without an underlying mass and a twisted pedicle, findings of torsion on ultrasound, are also seen on CT or MRI. Features that are better seen with CT or MRI include subacute ovarian hematoma and abnormal or absent ovarian enhancement.
What are the symptoms of a pelvic tumor?
What Are the Symptoms of Pelvic Masses?
- Pain.
- Fullness.
- Pressure.
- Bloating.
- Urinary or bowel changes.
- Decrease in appetite or feeling full quickly.
- Menstrual cycle abnormalities.
Can a pelvic mass cause leg pain?
Referred pain in the leg is occasionally due to a pelvic soft tissue tumour.
Can you see ovarian torsion on ultrasound?
An ultrasound (usually a transvaginal one) can confirm the diagnosis. “If a patient has severe pelvic pain and is nauseous and I can feel the cyst during a pelvic exam, we will use transvaginal ultrasound to see if the ovary is enlarged, which could indicate torsion,” Dr. Fan explains.
Is the pedicle a sign of ovarian origin?
RESULTS. The presence of the ovarian vascular pedicle sign was identified in 92% (99/108) of ovarian masses and in 13% (3/23) of subserosal uterine myomas. The sign was statistically significant (p< 0.01) for differentiating a mass of ovarian origin from a mass of subserosal uterine origin.
Why is the helical CT important for ovarian cancer?
The presence of the ovarian vascular pedicle sign on helical CT is valuable for confirming the ovarian origin of a pelvic tumor and for differentiating an ovarian tumor from subserosal uterine myoma.
What does the pedicle sign on helical CT mean?
“Ovarian vascular pedicle” sign revealing organ of origin of a pelvic mass lesion on helical CT The presence of the ovarian vascular pedicle sign on helical CT is valuable for confirming the ovarian origin of a pelvic tumor and for differentiating an ovarian tumor from subserosal uterine myoma.
What is the appearance of endometrial cancer on an ultrasound?
Appearance of endometrial cancer May resemble hyperplasia/polyps with uniformed thickened echogenic endometrium More commonly the endometrium is heterogenic with poorly defined borders Fluid filled endometrium with an irregular vasculized wall, polypoid lesions and ascitis
