Myocardial abscess, a rare form of cardiac aspergillosis




A 63-year-old woman with aplastic anaemia was admitted to hospital for fever and malaise. Computed tomography (CT) scan showed a cavitary nodular lesion in the left lower lobe, which was highly suspicious for pulmonary aspergilloma ( Fig. 1 A-1 ). A semilunar shaped, low-density lesion within the left ventricular free wall accompanied by mild pericardial effusion was found on the CT scan and magnetic resonance image ( Fig. 1 A-2 and B). Transthoracic echocardiography showed an echo-free lesion within the left ventricular anterolateral wall ( Fig. 1 C).

A-1. Preoperative CT scan showing cavitary lesion (red arrow) in the left lower lobe, which was later confirmed as aspergilloma. A-2. Preoperative CT scan showing low-density semilunar-shaped lesion within the left ventricular wall (yellow arrow). B. Magnetic resonance image demonstrating a 3.1 × 2.2 cm well-circumscribed oval-shaped mass in the anterolateral wall of the left ventricle. This lesion shows high signal intensity on both T1 and T2WI with a dark signal rim (left and middle box). C. Preoperative transthoracic echocardiogram showed echolucent pocket within the anterolateral ventricular wall (arrow). D. Postoperative 1-year CT scan showed no evidence of residual or recurrent abscess in the ventricular wall.
