  9. 9. Vaginography • Technique • Indications: 1. Fistula . 2. Congenital or acquired abnormalities of vagina . 3. To localize by reflux an ectopic ureter opening into vagina. Prof Soha Talaat
  10. 10. Vaginagraphy Prof Soha Talaat
  11. 11. Gynecologic US I. Scanning technique: A. TAS: • Uses transducers 3-5MHZ range. • Requires filling of the urinary bladder (ideal 1- 2 cm above the uterine fundus). • Obtained in sagittal and transverse planes (oblique image may be needed) • To view adnexa move transducer from side to side. • Main advantage providing an overview of the pelvis. Prof Soha Talaat
  12. 12. B.TVS • Performed with 5-9 MHZ transducers . • Empty bladder:  To minimize discomfort  Brings uterus and ovaries into focal zone. • Probe should be disinfected , Us gel applied to transducer head ,use condom . • AP& transverse pelvic planes. Prof Soha Talaat
  13. 13. TVS • Indications : 1. Early and second trimester pregnancy. 2. Lower uterine segment in late pregnancy. 3. Ectopic pregnancy. 4. Retroverted or retroflexed uterus. 5. Obese and gaseous patients. 6. Emergency cases where bladder is empty. 7. Follicular monitoring in ovulation induction. 8. Pulsed and colour Doppler. Prof Soha Talaat
  14. 14. TVS • Advantages: 1. Can be performed quickly without full bladder. 2. Determine source of pain more accurately. 3. Facilitates use of Doppler. 4. Biopsy guides :follicular aspiration ,cyst& abscess drainage , tumour biopsy. Prof Soha Talaat
  15. 15. TVS • Disadvantage : 1. Occasional confusion with anatomic orientation due to unfamiliar scan planes. 2. Limited field of view which allow only visualization of true pelvis . 3.

  33. 33. Embryology • The female reproductive system develops from the müllerian ducts , two ducts that originate in embryonic mesoderm lateral to each wolffian duct . • The paired müllerian ducts grow in medial and caudal directions .The most cephalad parts of the ducts remain separate and form the fallopian tubes .The lower parts of the ducts fuse (lateral fusion ) .The midline septum disappears ,leaving a single canal :the uterus and upper two -thirds of the vagina Prof Soha Talaat
  34. 34. Embryology • The lower third of the vagina develop from the bilateral sinovaginal bulbs which arise from the urogenital sinus .The sinovaginal bulbs fuse into solid mass called the vaginal plate ,which undergoes canalization in the second trimester ,the sinovaginal bulb fuses with the lower müllerian system (vertical fusion) . • The close developmental relationship of the müllerian and wolffian ducts explains the frequent association of anomalies of the female genital system and urinary tract Prof Soha Talaat
  35. 35. Müllerian duct anomalies are categorized most commonly into 7 classes according to (AFS) Classification Scheme (1988) : • Class I (hypoplasia/agenesis) • Class II (unicornuate uterus) • Class III (didelphys uterus) • Class IV (bicornuate uterus) • Class V (septate uterus) • Class VI (arcuate uterus) • Class VII (diethylstilbestrol-related anomaly) Prof Soha Talaat
  36. 36. The modified American Fertility Society (AFS) by Rock and Adam • Class 1: Dysgenesis of müllerian ducts. This class includes agenesis or hypoplasia of the müllerian duct derivatives: the uterus and upper two-thirds of the vagina. The most common form is the Mayer- Rokitansky-Kuster-Hauser syndrome (MRKH syndome), which is combined agenesis of the uterus, cervix, and upper portion of the vagina. • Class 2: Disorders of vertical fusion. These anomalies are due to failure of fusion of the müllerian system with the sinovaginal bulb. They include cervical dysgenesis and obstructive and non obstructive transverse vaginal septa. Prof Soha Talaat
  37. 37. The modified American Fertility Society (AFS) by Rock and Adam • Class 3: Disorders of lateral fusion : result in a duplicated or partially duplicated reproductive tract. The disorders are due to impaired fusion and/or septal resorption of fusing müllerian ducts attempting to form the uterus, cervix, and upper vagina. Failure of fusion of the paired müllerian ducts (as in didelphic and bicornuate uteri) and failure of midline septum resorption after fusion (as in septate uterus). Disorders due to lateral fusion defects are further subclassified into (a) the symmetric non obstructive form seen in five types: unicornuate, bicornuate, didelphic, septate, and DES-related uteri and (b) the asymmetric obstructive form seen in three types: unicornuate uterus with obstructed horn, double uterus with unilaterally obstructed horn, and double uterus with unilaterally obstructed vagina. • Class 4: Unusual configurations and combinations of defects [14].

  179. 179. Benign diffuse enlargment Torsion( edema) • Ovarian torsion (adnexal torsion) is an infrequent but significant cause of acute lower abdominal pain in women. • This condition is usually associated with reduced venous return from the ovary as a result of stromal edema, internal hemorrhage, hyperstimulation, or a mass. Prof Soha Talaat
  180. 180. •An enlarged ovary (>5 cm) • Prominent peripheral nonovulatory follicles . •Small amount of free fluid •May depict the cyst (or, less commonly, the mass) that predisposed the ovary to torsion. US Prof Soha Talaat
  181. 181. •Imaging modality of choice •An absence of arterial waveforms or high resistance to arterial flow with absent venous flow are highly suggestive. • Particularly when those findings are accompanied by ovarian enlargement. •However normal arterial waveforms do not rule out torsion. Doppler Prof Soha Talaat
  182. 182. Diffuse ovarian enlargment Ovarian malignancies include epithelial, stromal and germ-cell tumors. Primary malignancies that may exhibit metastases to the ovaries include gastrointestinal, breast and soft tissue tumors such as lymphoma Prof Soha Talaat
  183. 183. Malignant diffuse enlargement Krukenberg •Metastatic signet ring cell adenocarcinoma of the ovary. •uncommon, 1% to 2% of all ovarian tumors •80% bilateral Prof Soha Talaat
  184. 184. Ovarian lymphoma • Primary female reproductive system lymphomas are distinctly uncommon. • genital involvement is more likely a component of widely disseminated disease. NHL of the ovary may be a source of pelvic retroperitoneal masses completely engulfing the internal female genitalia. Prof Soha Talaat
  185. 185. Ovarian lymphoma • lymphoma of the ovary may appear as a discrete hypoechoic mass or a large confluent aggregate mass that may fill the pelvis. Hyperemia is often observed • CT may reveal low-attenuation solid masses involving the uterus or confluent masses displacing or engulfing the pelvic organs Prof Soha Talaat

  187. 187. Sonographic anatomy • The fallopian tubes:  Normal tubes could not be detected by US.  Test for tubal patency(sonohysterography) • The cul de sac;  Most dependent part of peritoneal cavity.  Normal findings a small amount of peritoneal fluid . • Urinary bladder : anechoic , normal wall thickness . Prof Soha Talaat

  189. 189. Hydrosalpinx • Hydrosalpinx, pyosalpinx, and hematosalpinx are used to describe a dilated fallopian tube filled with fluid, pus, or blood, respectively. • Blockage usually occurs at the fimbriated end of the fallopian tubes and is caused by adhesions from infectious or inflammatory processes. • The most common causes of hydrosalpinx are pelvic inflammatory disease and endometriosisProf Soha Talaat
  190. 190. Prof Soha Talaat
  191. 191. Pyosalpinx • Color Doppler US image shows a hypoechoic tubular structure(arrow) containing echogenic debris. There is no internal blood flow; however, there is increased surrounding vascularity. Prof Soha Talaat

  193. 193. What about fallopian cancer Fallopian tube cancer is the least common of gynecological malignancies (0.3%) . It was first described by Renaud in 1847.1 Since then, there have been over 1500 cases Prof Soha Talaat

The common mullerian origin of fallopian tube and ovarian cancer could explain the cytological and histological similarities between them. Difficulties in diagnosis exist due to the similarities shared between fallopian tube carcinoma and epithelial ovarian carcinoma Prof Soha Talaat
  198. 198. 2-2ry tumors: • Tubal involvement often by ovarian borderline tumors and carcinomas, cervical and endometrial carcinoma (invasive or in-situ) and pseudomyxoma peritonei • Metastases from extra-genital site are rare Mode of transmission *direct *lymphatic *blood *transcelomic Prof Soha Talaat
