Recurrent rectal carcinoma in an asymptomatic patient.

Pelvic recurrence is a common cause of symptoms and mortality in patients who have undergone surgical resection of rectal carcinoma. Diagnosis by physical examination and standard radiologic techniques is usually only possible when the recurrence becomes symptomatic because of its advanced state. Previous reports have documented the ability of computed tomography (CT) to depict accurately pelvic recurrence of rectal carcinoma in the symptomatic patient. Surgical resection of recurrence is usually noncurative but appears to result in a more prolonged survival if performed in the asymptomatic patient. We report a case of pelvic lymph node recurrence suggested by CT and confirmed by CT guided needle biopsy in an asymptomatic patient. Diagnosis of recurrence at this early stage by CT, supplemented with CT guided biopsy, may offer the patient an increased chance of survival following surgical resection.
