What is parametrial invasion?
When a distinct smooth muscle layer in the outermost cervix was used, parametrial invasion was defined as disruption or discontinuity of the cervix’s outer smooth muscle layer caused by direct tumor growth, desmoplastic reaction, or tumor cells found outside the circumferential smooth muscle bundles.
What is the parametrium?
The fat and connective tissue that surrounds the uterus. The parametrium helps connect the uterus to other tissues in the pelvis.
What is bilateral parametrium?
Anatomical terminology. The parametrium is the fibrous and fatty connective tissue that surrounds the uterus. This tissue separates the supravaginal portion of the cervix from the bladder. The parametrium lies in front of the cervix and extends laterally between the layers of the broad ligaments.
What is Trachelectomy procedure?
A radical trachelectomy is surgery to remove your cervix and tissue from around your cervix. You may be having a radical trachelectomy because you have cervical cancer. During your radical trachelectomy, a large part of your cervix and tissue around it will be removed (see Figure 1).
What is a Parametrial mass?
1), parametrium refers to the tissue located cranially to the ureter, between the uterine corpus and the pelvic sidewall, surrounding the uterine artery. The parametrium includes the superficial uterine pedicle (uterine artery and superficial uterine vein) and related connective tissue and lymphatic channels.
Why do you get Pap smears?
The Pap test (or Pap smear) looks for precancers, cell changes on the cervix that might become cervical cancer if they are not treated appropriately. The HPV test looks for the virus (human papillomavirus) that can cause these cell changes.
How do you examine parametrium?
Rectovaginal examination is performed by inserting the index finger into the vagina and the third finger in the rectum. The rectovaginal septum and the distal portion of the cul de sac can be evaluated for any anatomic distortions or tenderness.
What is acute Parametritis and pelvic cellulitis?
Specialty. Gynecology. Parametritis (also known as pelvic cellulitis) is an infection of the parametrium (connective tissue adjacent to the uterus). It is considered a form of pelvic inflammatory disease.
What is cervical mass?
A cervical polyp is a growth that develops on the cervix, which is the canal connecting the uterus to the vagina. Sperm must pass through this canal to fertilize an egg. Cervical polyps are tumors, but they are usually non-cancerous, or benign.
Is there a MRI that can detect parametrial invasion?
The parametrium is the anatomical space lateral to the cervix. The reported accuracy of MRI in detecting parametrial invasion varies in the literature from 76 to 92% 2. MRI does however have a high negative predictive value in excluding parametrial invasion. If the T2 hypointense cervical ring is intact, then parametrial invasion is unlikely.
How is parametrial invasion determined in cervical cancer?
Thus, accurate evaluation of parametrial invasion is important to make clinical decisions and to select the optimal treatment. Generally, parametrial invasion in cervical cancer is evaluated by using T2-weighted imaging, in which a preserved hypointense stromal rim is a specific finding for exclusion of parametrial invasion ( 5, 6 ).
Can a MRI detect parametrium in cervical cancer?
The parametrium is the anatomical space lateral to the cervix. The reported accuracy of MRI in detecting parametrial invasion varies in the literature from 76 to 92% 2. MRI does however have a high negative predictive value in excluding parametrial invasion.
How does MRI anatomy of parametrial extension help?
In particular, the knowledge of MRI anatomy of parametrial extension can help to correctly assess the local involvement of disease by imaging. The lateral, anterior, and posterior parametrial extensions are easily identified on T2-weighted imaging, while DWI can help the diagnosis of parametrial neoplastic involvement.
