双子宫（Uterus Didelphys） Uterus Didelphys  Representative line diagram depicting right renal agenesis, uterine didelphys, and vaginal septum Herlyn-Werner-Wunderlich (HWW) syndrome Bicornuate Uterus Septate Uterus Arcuate uterus DES Uterus 复杂畸形 完全型纵隔子宫合并双宫颈管（罕见） THANK YOU SUCCESS * * 可编辑 * HSG demonstration of septate versus bicornuate uteri. (a) Acute angle of divergence between uterine horns is most suggestive of a septate uterus (arrow). (b, c) Indeterminate angles of divergence may suggest either (b) septate uterus (arrow) or (c) bicornuate uterus (arrow). Final diagnoses were based on subsequent MR imaging results (not shown). * 。 * The various Mullerian duct anomalies can be categorized broadly as follows: Class 1: Segmental agenesis and variable degrees of uterovaginal hypoplasia Class 2: Unicornuate uteri that represent partial or complete unilateral hypoplasia Class 3: Uterus didelphys, in which duplication of the uterus results from complete non-fusion of the mullerian ducts Class 4: Bicornuate uteri that demonstrate incomplete fusion of the superior segments of the uterovaginal canal Class 5: Septate uteri that represent partial or complete non-resorption of the uterovaginal septum Class 6: Arcuate uteri that result from near complete resorption of the septum Class 7: Comprise sequel of diethylstilbestrol exposure?in utero Mayer-Rokitansky-Küster-Hauser syndrome. (a) Sagittal T2-weighted MR image shows complete absence of the cervix and uterus with an abnormally truncated vagina ending in a blind pouch (arrowhead) between the rectum (r) and urinary bladder (b). (b) Axial T2-weighted image shows the presence of normal ovaries (*). Unicornuate uterus with no rudimentary horn. (a) Illustration shows a right unicornuate uterus with no rudimentary horn. (b) HSG image shows a small, oblong uterine cavity (*) deviated to the right of midline with a single fallopian tube (arrowhead). (c) Axial T2-weighted MR image shows a single uterine horn (*) and cervi
