Pelvic MRI of the tumor showing a large retrorectal cystic mass with solid mural nodule. A sagittal T2 weighted pelvic MRI (a) demonstrated a large predominantly cystic mass () which is anterior to the sacrum and coccyx (green arrow) and posterior to the rectum (red arrow). An unenhanced fat suppressed T1 weighted axial image (b) and a gadolinium enhanced fat suppressed T1 weighted axial image (c) demonstrated an enhancing nodule (blue arrow) in the posterior portion of the mass.
