Antenatal diagnosis of hydrometrocolpos with Mullerian duplication on ultrasound and fetal MRI: case report and literature review

Abhinav Chander Bhagat et al. BJR Case Rep. .

Abstract

Fetal abdomino-pelvic cystic lesions are uncommon and can have varied etio-pathogenesis. Most commonly they originate from the gastrointestinal or genitourinary tract. These include choledochal cyst, hydronephrosis, renal cyst, mesenteric/omental cyst, ovarian cyst, meconium pseudocyst, and hydrocolpos/hydrometrocolpos among others. Fetal hydrometrocolpos is rare with a reported incidence of 0.006% and its diagnosis requires a high index of suspicion. Antenatal ultrasound and magnetic resonance imaging (MRI) is invaluable in diagnostic evaluation. This case report describes the imaging features of antenatally detected congenital hydrometrocolpos with Mullerian duplication secondary to cloacal malformation using antenatal ultrasound and MRI. Per-operative findings and other possible differential diagnoses are discussed along with a brief review of literature.

(a-d). Antenatal ultrasound images in coronal plane (a,b) showing the distended vagina (*) with central echogenic vertical septum funneling towards the pelvis (straight arrows) and distended hemiuteri at the cranial aspect of distended vagina (square arrows). Images in the axial plane (c,d) reveal bilateral renal pelvic dilatation (p) and anteriorly displaced urinary bladder (curved arrow) with fetal ascites (a).

(a-d). T2-weighted fetal MR images in sagittal (a), axial (b), and coronal (c) planes show the distended vagina (*) with central linear hypointense vertical septum displacing the bladder (b) anteriorly against the abdominal wall, bilateral renal pelvic dilatation (p) and fetal ascites (a). Sagittal T1-weighted MR image (d) reveals hyperintense meconium within non-dilated rectum seen reaching upto the perineum.
