Findings and diagnosis
Findings
- ECG-gated unenhanced CT of the heart: Focal dilatation of the midright coronary artery.
- ECG-gated CTA of the heart: Focal dilatation of the mid-RCA with the transverse diameter measuring greater than the longitudinal diameter, which in keeping with a saccular aneurysm. There is an associated layering thrombus in the aneurysm without critical stenosis.
Differential diagnosis
- Pseudoaneurysm
- Giant coronary artery aneurysm
- Fusiform aneurysm
- Saccular aneurysm
Diagnosis: Saccular aneurysm of the right coronary artery
