Summary
Multiple adrenal pseudotumors can mimic real tumors on imaging. This case shows normal colon interposition mimicking an adrenal pseudotumor on CT scans.
Area of Science:
- Radiology
- Abdominal Imaging
- Gastrointestinal Radiology
Background:
- Adrenal pseudotumors are rare entities that can be mistaken for adrenal neoplasms.
- Computed Tomography (CT) is a primary imaging modality for evaluating adrenal lesions.
Observation:
- A case report detailing a patient with an apparent right adrenal pseudotumor on CT.
- The pseudotumor appearance was caused by the unusual anatomical positioning of normal colon.
Findings:
- Interposition of normal colon within the hepatorenal recess was identified.
- This anatomical variation mimicked the imaging characteristics of a right adrenal pseudotumor.
Implications:
- Highlights the importance of recognizing anatomical variations in abdominal imaging.
- Enhances diagnostic accuracy by differentiating pseudotumors from true adrenal masses.
- Crucial for avoiding unnecessary investigations and interventions for adrenal lesions.
