a–e Follow-up Post contrast CT study for the same patient in Fig. 4. a–e coronal, axial and sagittal images revealed: slight progression of the rectal disease process regarding the maximum thickness (2.8 cm, compared to 2.5 cm on the previous scan); (which could be pseudo-progression due to cystic or mucinous degeneration of the primary tumor; rather than actual viable tumoral progression, this considered a limitation of conventional CT alone). However, no appreciable size or number changes regarding the previously noted calcified LNs, confirming on viable nodal lesions
