Abstract

MARTINEZ-MILLAN, Sergio et al. Post-processing of colon tomographic images for the diagnosis of challenging cases. Case report. Gen [online]. 2025, vol.79, n.4, pp.209-218.  Epub Oct 15, 2025. ISSN 0016-3503.  https://doi.org/10.61155/gen.v79i4.756.

Three-dimensional post-processing (3D) of colonic tomographic images was applied in two patients with uncertain diagnoses. In the first case, the presence of colo-colonic fistulas was suspected, while in the second, a giant solitary sigmoid diverticulum was considered. Surgical treatment was initially indicated for both patients. After further evaluation with 3D post-processing, the preliminary diagnoses were excluded, the true underlying causes of symptoms were identified, and unnecessary surgery was avoided. These cases highlight the clinical value of 3D tomographic image post-processing as a complementary tool for assessing complex scenarios in which precise delineation of colonic anatomy is essential.
