Local recurrence of rectosigmoid cancer: What about the choice of MRI for diagnosis?


Local recurrence is a frequent event in the natural history of rectosigmoid cancer. The diagnostic possibilities, as well as the limits of computed tomography (CT) and transrectal ultrasonography (TRU), are well known in these conditions. The aim of our study was to define the possible role of magnetic resonance imaging (MRI). We considered 15 examinations carried out in 14 patients, seven of which were obtained before and after Gd-DTPA administration. MRI demonstrated a 93.3% accuracy, 100% sensitivity, and 83.3% specificity in relation to the presence of local recurrence. The presence of pelvic recurrence was suggested on the basis of morphological and signal criteria. The use of paramagnetic contrast gave additional information in four of seven patients. The use of Gd-DTPA may be most beneficial in patients suspected of recurrence, within 6 months of their last treatment, where the diagnosis is more difficult.
