Abstract

Müllerian Duct Cyst (MDC) is a rare congenital intraprostatic cystic lesion that arises from remnants of the Müllerian ducts. Typically found incidentally in males during the 3rd and 4th decades of life, MDCs are usually asymptomatic but can lead to urinary retention and ejaculatory duct obstruction if they reach significant size. Imaging techniques, particularly pelvic MRI, are crucial for diagnosis, providing detailed anatomical visualization. Differentiation from prostatic utricle cysts (PUCs) and other cystic lesions is essential, as they present similar characteristics. While most prostatic cysts are benign, rapid growth or irregularities may indicate malignancy, necessitating surgical intervention for symptomatic or malignant cases. Accurate diagnosis requires comprehensive imaging and clinical assessment.
We present a case of a typical MDC found incidentally in a male patient with urinary stone disease. This case underscores the significance of magnetic resonance imaging (MRI) in diagnosing and differentiating prostatic and peri-prostatic cysts.
