Postpartum ultrasonographic examination showed that there was a 7.5 x 8.5 cm sized thin-walled cystic lesion in the midline of the pelvic region compressing the rectum, uterus and bladder (Figure 1).
Sagittal T2-weighted MRI images of the thin-walled hyperintensity in the posterior of the uterus and the rectum (a) and hypointense cystic lesion on T1-weighted images (b). The 4th and 5th sacral bones are not seen. In the posterior of the cyst, communication with spinal subarachnoid space is present. The contrast enhancement is not observed in sagittal postcontrast T1-weighted images (c). Conus medullaris ends at the level of the 4th lumbar spine. The distinct arcuate uterus is seen in the coronal T2-weighted images (d).
