Highlights the role of multimodality imaging (USG, CT, MR) in diagnosing rare congenital left atrial appendage aneurysms to prevent complications.
May aid early detection of rare LAA aneurysms via multimodality imaging; leaves open natural history and intervention thresholds.
Aneurysm of left atrium may involve the left atrial wall or left atrial appendage. Aneurysm of left atrial appendage is usually acquired in etiology secondary to mitral valve disease, whereas its congenital variant is a rare developmental anomaly. Congenital left atrial appendage aneurysm is very rarely reported entity. They lead to complications like systemic emboli, arrhythmias and worst as death. They are usually misdiagnosed most of the times as a mediastinal mass or cardiac tumour on Chest X-ray. USG provides an easily accessible modality in providing a provisional diagnosis, in confirming the location and its communication with the mediastinal vascular structures. Cardiac and coronary CT and MR help in providing a conclusive diagnosis and earlier surgical intervention thereby preventing further mortality or morbidity. We report a case of 20 year old female incidentally diagnosed with left atrial appendage aneurysm.
