HWW SYNDROME | MR FINDINGS |
---|---|
Uterus didelphys | It is characterized by two symmetric, widely divergent uterine horns and two cervixes, with an enlarged cavity filled by bloody/proteinaceous fluid due to haematocolpos. It appears hyperintense signal on T1 fat saturated sequences. |
Hemivagina | It is an obstructed vagina due to a longitudinal septum which occludes one cervix and isolates it with consequent hematometra. |
Renal aplasya | It is tipically omolateral to the vaginal anomaly (right side prevalence), with possible controlateral renal hypertrophy due to compensation but in site. |
Ovaries | Possible presence of endometriosic cysts with hyperintense signal on T1 fat sat sequences and with "shading sign" on T2-weighted images and a gradual variation of signal intensity due to chronic bleeding with accumulation of high concentration of iron and protein in the endometrioma (endometriotic lesions appear hyperintense on T1-weighted images and mildly hypointense or hyperintense on T2-weighted images). Possible presence of functional cysts with no clinical significance, which appear hyperintense on T2 sequences and hypo/isointense on T1 sequences. |
