Overview
Abdominal CT scan is pretty helpful in the diagnosis of appendix cancer. Findings on CT scan suggestive of appendix cancer include [finding 1], [finding 2], and [finding 3]. CT scan is one of the best imaging modalities to assess disease burden, metastatic lesions as well as disease stage.
CT scan
- Abdominal CT scan may be helpful in the diagnosis of appendiceal cancer. Findings on CT scan suggestive of appendix cancer include:
- Cystic lesion
- Peritoneal involvement
- Liver metastasis
- Peritoneal carcinomatosis index (PCI): a widely accepted metric for assessment of disease border in appendix cancer
- Estimated by contrast enhanced cross sectional imaging.
- Both MRI and CT scan has been used and are globally accepted imaging modalities.
- Small peritoneal seeding might be difficult to appreciate on CT.
- Sometimes it is challenging to distinguish between tumor and mucin.
- There are reports in favor of Diffusion weighted MRI superiority compared to CT in evaluating extent of peritoneal involvement.[1]
- CT scan also helps in discovering distant metastatic lessons in the other organs like bone, lungs, and brain.
