From July 1, 1981 to August 31, 1984, 59 patients who had radiation therapy for carcinoma of cervix had CT scanning at Department of Diagnostic Radiology, Kosin Medical College. The authors analysed the CT findings of the patients in regard to the recurrence of the disease and postradiation changes. The results are as followings; 1. The incidence of recurrence was most common in advanced stage over llb. 77% 2. Changes in pelvic cavity were as followings; Widening of presacral space 78%; Increased perirectal fat space 81%; Symmetrical thickening of perirectal fascia 97%; Fibrous conncetion between sacrum and rectum 92%; Anterior connection between rectum and perirectal fascia 47%; Increased bowel wall thickness 44%; Increased bladder wall thickness with trabeculations 51%. 3. In most patients who had CT scanning within 3 months after radiation therapy, CT did not demonstrate postradiation changes characterized by an increased pelvic fibrous and fatty tissue. 4. In 10 patients w o had postoperative radiation therapy, 8 patients show increased bowel wall thickness. 5. 30 patients with recurrent carcinoma of cervix were as followings; Pelvic tumor recurrence 90%; Parametrial and side wall extension 53%; Pelvic and paraaortic lymphadenophthy 40%; Hydronephrosis 23%' Bladder involvement 23%; Lumbar spine involvement 10%. And 1 patient shows distant metastasis to paraaortic lymph node, 1 patient to lumbar spine, and 1 patient to liver without recurrent tumor mass in pelvic cavity. 6. 2 patients showing mass without other sign in the pelvic cavity were unable to be differentiated between irradiated uterus and recurrent tumor.
