CTICasesMitral Valve Abscess and Vegetation
Imaging findings
The patient had a history of iatrogenic esophageal perforation and subsequent esophageal stent placement. Chest CT demonstrates abnormal thickening and a low-attenuation lobular area along the anterior leaflet of the mitral valve. Intracardiac echocardiography later confirmed a mitral valve abscess along with an aortic valve vegetation, which was associated with positive blood cultures for Streptococcus mitis.
Key takeaways
Chest CT can serve as a valuable diagnostic tool for detecting infective endocarditis and valve abscesses, especially when transesophageal echocardiography (TEE) is contraindicated or technically precluded due to severe esophageal pathology, such as esophageal stents or perforations.
