Objective: To study the role of MRI in pre-operative evaluation of obstructing congenital uterine and vaginal anomalies in adolescent girls presenting with hematometrocolpos.
Methodology: This study was conducted in Radiology department, Holy family Hospital, Rawalpindi. The study included 15 adolescent female patients presenting to Radiology department with clinical of sonographic suspicion of hematocolpos or hematometra.
Results: Out of the 15 patients, 6(40%) had imperforate hymen, 5(33.3%) distal vaginal atresia, 3(20%) transverse vaginal septum and one (6.6%) had cervico-vaginal agenesis. All (100%) had hematometra while hematocolpos was seen in 14(93.3%) patients. Three(20%) patients had hematosalpinx and endometriotic cysts. MRI findings were correlated with surgical findings giving MRI a sensitivity, specificity and accuracy of 100%.
Conclusion: Congenital obstructive anomalies of uterus and vaginal were diagnosed accurately with MRI. It is the investigation of choice in determining the accurate pre-operative level of obstruction and associated uterine anomalies.
Key words: Magnetic Resonance Imaging (MRI), Imperforate Hymen, vaginal atresia, vaginal septum, cervical agenesis.
