RESUMEN
We present the case of a 22-year-old woman with cesarean section 11 days before with abdominal pain in the left flank of one week of evolution associated with self-limited liquid stools. In the analytical control, leukocytes at the expense of neutrophils, as well as CRP 147 gr/L were highlighted. An abdominal CT scan was requested without contrast iv, which showed inflammatory changes in the pericolonic fat adjacent to the descending colon associated with concentric mural thickening with oval lesion. Due to the characteristics of the patient continuing with abdominal pain and the CT findings, abdominal MRI was requested in which concentric mural thickening of a segment of descending colon with longitudinal diameter of approximately 6 cm, associated with infiltration-rarefaction of the pericolonic fat, and cystic image that protrudes on the left lateral wall of the colon of approximately 3.7x5 cm was observed.
