BACKGROUND: Aim of our study was to assess the ability of computed tomography to distinguish between an intussusception with a lead-point from one without it. METHODS: Approval was granted by the Institutional Review Board. Ninety-three consecutive patients diagnosed with an intussusception on abdominal CT were classified with or without lead-point by surgery, clinical or radiological follow-up. Two radiologists blinded to the classification independently reviewed the CT images for predefined predictive variables. RESULTS: Non-lead-point intussusception was shorter in length (mean 4.9 vs. 11.1 cm for Reader 1 (R1); mean 4.0 vs. 8.9 cm for Reader 2 (R2), respectively, P < 0.001), smaller in axial diameter (mean 3.0 vs. 4.8 cm for R1; mean 2.8 vs. 4.4 cm for R2, P < 0.001, respectively), less likely associated with obstruction (P = 0.002 R1; P = 0.039 R2) and infiltration (P < 0.001 for R1, P = 0.003 R2) than lead-point intussusception. CONCLUSIONS: Abdominal CT is helpful in distinguishing between an intussusception with a lead-point from one without a lead-point. Length, axial diameter, and their product, as well as obstruction and infiltration, all suggest the presence of a lead-point. Analysis of CT findings can reduce unnecessary imaging follow-up or operation.
