Colonic spasm: a possible mechanism for thumbprinting.
Journal of the Canadian Association of Radiologists
|June 1, 1984
Summary
Colonic thumbprinting, a sign often indicating ischemic colitis, can also be caused by colonic spasm. Further evaluation revealed no abnormality, suggesting spasm as a potential cause for this radiographic finding.
Area of Science:
- Gastroenterology
- Radiology
- Pathology
Background:
- Ischemic colitis is a condition characterized by inflammation and damage to the colon due to reduced blood flow.
- Radiographic findings, such as thumbprinting on contrast enemas, are often indicative of ischemic colitis.
Observation:
- A patient presented with colonic thumbprinting on a contrast examination of the colon.
- This radiographic finding was typical of ischemic colitis both clinically and radiographically.
Findings:
- Despite the radiographic appearance suggestive of ischemic colitis, subsequent surgical and pathologic evaluations revealed no significant abnormalities.
- Colonic spasm emerged as a potential explanation for the observed thumbprinting, challenging the initial diagnosis.
Implications:
- This case highlights the importance of considering alternative diagnoses, such as colonic spasm, when interpreting radiographic findings suggestive of ischemic colitis.
- It underscores the need for comprehensive evaluation to avoid misdiagnosis and unnecessary interventions in cases of colonic thumbprinting.
