Reproductive: Acquired Flashcards
Salpingitis isthmica nodes (nodular scarring of the Fallopian tubes)
Note: Usually involving the proximal 2/3 of the uterine tubes.
Salpingitis isthmica nodosa is strongly associated with…
Infertility and ectopic pregnancy
Persistant vaginal bleeding s/p dilation and curettage
Think uterine AVM
Note: Tubular/serpiginous anechoic structure in uterine myometrium with high velocity color Doppler.
Infertility
Think Asherman’s syndrome
Note: Multiple intrauterine filling defects.
Fever
Think endomteritis
Note: Irregular thickening of the endometrium (yellow arrow) and fluid-filled endometrial cavity containing gas (blue arrow).
Endopelvic facia
Ligaments and fascia that provide the main support for the anterior and middle pelvic compartments (bladder/urethra and vagina/cervix/uterus)
Levator ani
The main muscular component of the pelvic floor composed of the puborectalis, pubococcygeus, and iliococcygeus
Urogenital diaphragm
An anatomic landmark (the most caudal/superficial musculofascial structure of the pelvic floor) used to classify urethral injury
What are the two components of pelvic floor relaxation?
- Pelvic floor descent
- Pelvic floor widening
Note: These can be graded on sagittal MRI during maximum strain.
Pubococcygeal line
A line drawn from the inferior margin of the symphysis pubis to the junction between the first and second coccygeal elements
Note: This is helpful when evaluating the pelvic floor on MRI.
H line (pelvic floor MRI)
A line drawn from the inferior margin of the pubic symphysis to the posterior aspect of the puborectalis muscle sling
Note: This is helpful when evaluating hiatal enlargement of the pelvic floor on MRI.
M line (pelvic floor MRI)
The shortest distance between the posterior aspect of the puborectalis muscle sling and the pubocyccygeal line
Note: This is helpful when evaluating pelvic floor descent on MRI.
What is considered hiatal enlargement when evaluating the pelvic floor on MRI?
H line >6 cm (pubic symphysis to puborectalis muscle sling)
What is considered abnormal hiatal descent when evaluating the pelvic floor on MRI?
M line >2 cm (puborectalis muscle sling to pubococcygeal line)
Imaging features of pelvic floor dysfunction
- Hiatal enlargement (H line >6 cm)
- Longer pelvic floor descent (M line >2 cm)
