Twenty-five patients with squamous-cell or cloacogenic carcinomas of the rectum were evaluated by computed tomography (CT). CT provided excellent definition of tumor extent, including local spread, lymph node involvement and distant metastases. In one of seven pretherapy studies, CT findings significantly altered patient management. Tumor recurrence was correctly identified in 14 or 19 patients having post-therapy scans, although CT-guided biopsy was required to confirm the presence of malignancy in three cases. Extensive soft-tissue stranding in the ischiorectal fossa and/or perirectal fat associated with a large focal mass occurred in all patients with local tumor recurrence. Stranding was also seen in all patients treated with radiation. CT is an excellent method for preliminary evaluation and follow-up of patients with anal epithelial neoplasms, facilitating rapid and effective management.
