Computed tomographic diagnosis of radiation ileitis
Gastrointestinal Radiology
|January 1, 1984
Summary
Computed tomography (CT) scans identified radiation ileitis in two patients post-colon cancer surgery and abdominal radiation. Findings included bowel loop changes and mesenteric fat alterations, distinguishing it from recurrent tumors.
Area of Science:
- Radiology
- Oncology
- Gastroenterology
Background:
- Post-surgical management of colon carcinoma often involves radiation therapy.
- Abdominal radiation can lead to gastrointestinal complications, including small bowel injury.
Observation:
- Computed tomography (CT) imaging was utilized to evaluate two patients after colon cancer resection and abdominal radiation.
- Specific imaging findings were noted, including localized bowel loop changes and mesenteric alterations.
Findings:
- The observed CT findings included a localized, mass-like confluence of shortened bowel loops.
- Thickening of the bowel wall, adherence of adjacent loops, thickened mesentery, and increased mesenteric fat density were present.
- These findings were consistent with radiation ileitis.
Implications:
- CT imaging findings can help diagnose radiation ileitis in patients treated for colon cancer.
- Distinguishing radiation ileitis from recurrent colon carcinoma is crucial for patient management.
- A 1-year asymptomatic follow-up and autopsy confirmed the absence of recurrent tumor, supporting the diagnosis of radiation ileitis.
