case_images: The abdominal-pelvic CT scan revealed an 88/64 mm presacral tumor with a right pararectal development and a mass effect on the rectum, against which there was no cleavage plan; there was no relationship with the iliac vessels (Figure 1).

case_images: Cytological examination of the fluid revealed a benign smear, and histopathology revealed an 8/3/1 cm cyst lined by non-keratinized stratified squamous epithelium without a granular layer, fibrous connective tissue walls with reduced inflammatory lymphoplasmacytic infiltration, and hemorrhage areas (Figure 2).
