Abstract

The study aimed to describe clinical features, magnetic resonance imaging (MRI) of perineal endometriosis (PE) and evaluation of the invasion to the external anal sphincter of MRI in PE. We performed a cross-sectional descriptive study of PE patients who took 1.5T MRI at Viet Duc Friendship Hospital from 7/2019 to 7/2022. Total of 26 patients, the average age was 33.38. The mean size of the lesion was 24.69 mm. On MRI: 90% hyperintensity on T1W, 73% hyperintensity on T2W, 100% hyperintensity on T1fatsat and T2 fatsat, 96.2% hyperintensity on Diffusion, 92.8% with enhancement after injection, 69.2% with anal external sphincter involvement, 19.2% with concurrent pelvic endometriosis. The sensitivity of MRI in the diagnosis of PE is 88.5%. The consensus index of MRI and surgery in diagnosing PE is 0.623. MRI in the assessment of invasion of the external anal sphincter has a sensitivity of 84.2% and a specificity of 71.4%.
