RESUMO
The solitary intraperitoneal fibrous tumor is a rare lesion, almost exclusively benign. We report on three cases with different ultrasound, computed tomography and magnetic resonance imaging findings, related to the fibrous and/or cellular histological composition of the tumor. Because of the minimal, but real, possibility of a recurrence after the surgical intervention, a follow-up by radiological imaging is recommended.

Diffuse retroperitoneal fibrosis (RPF) is a rare inflammatory process. We report on two known cases of RPF, without evidence of involvement of the urinary tract or of the venous system. A computed tomography (CT)-guided biopsy was performed in each case, and the histological findings eliminated other pathological processes, particularly those of malignant origin. In both cases, a therapy with cortisone was instituted, and a follow-up with CT at 6 months has demonstrated a regression of the pathology of more than 50%.

Colocolic intussusception in the adult, caused by a tumoral process, is a rare clinical event. We have studied two adults clinically presenting with a mass in the right iliac fossa, which was produced in one case by a carcinoma involving the right colon and in the other case involving the sigmoid. Multi-slice spiral CT imaging showed the presence of a colocolic intussusception-the tumoral characteristics of the lesion eliminated the possibility of a lipoma-and it allowed a satisfactory presurgical evaluation of the pathological process.
