Abstract
Objective

To review the spectrum of benign and malignant rectal diseases, their findings on CT colonography, and their management.

Conclusion

Although CT colonography is not the first choice for the study of rectal disease, it is indicated in cases where optical colonoscopy is contraindicated or cannot be completed. Rectal lesions can go undetected because this anatomic area is difficult to evaluate; for this reason, it is essential to ensure optimal preparation and distension, moderate balloon insufflation, and careful 2D and 3D navigation with knowledge of the spectrum of rectal disease and its CT colonography signs.

Resumen
Objetivo

Revisar el espectro de la patología rectal benigna y maligna, sus hallazgos en la colonografía-TC (CTC) y su manejo.

Conclusión

Aunque la CTC no es la herramienta de primera elección para el estudio de la patología rectal, está indicada en casos de colonoscopia óptica incompleta o contraindicada. Las lesiones rectales pueden pasar desapercibidas por la dificultad que representa la valoración de esta área anatómica, y por ello es necesaria una excelente preparación y distensión, la insuflación moderada del balón y una navegación cuidadosa en 2D y 3D con conocimiento del espectro de la patología rectal y su semiología en CTC.
