“…Due to its rare occurrence, isolated myocardial abscess without IE is rarely described in the guidelines for prevention and treatment of IE published by the Japanese Society of Cardiology [ 2 ], limiting its diagnosis and treatment. Decubitus ulcers, infections associated with burns, bronchiectasis, and sepsis due to thrombophlebitis in immunocompromised patients are associated with isolated myocardial abscesses [ 5 ]. There are reports of abscess formation at the site of myocardial infarction [ 6 ]; however, the present case occurred without any risk of abscess formation in the present case.…”

Background Myocardial abscess is often associated with infective endocarditis (IE), and isolated myocardial abscess without IE is rare. Echocardiography and computed tomography (CT) are often used to diagnose myocardial abscess; however, to the best of our knowledge, diffusion-weighted whole-body magnetic resonance imaging with background body signal suppression (DWIBS) has not been used. Here, we present a case of myocardial abscess without IE that was diagnosed using DWIBS. Case presentation : A 72-year-old Japanese man with a history of hypertension, dyslipidemia, and retinitis pigmentosa presented to our hospital with malaise and a fever lasting 10 days. Blood test results showed elevated inflammatory marker levels (white blood cell count 18,700/µL and C-reactive protein level 23.0 mg/dL). Infection was suspected; however, the source of the infection could not be identified. DWIBS, which was performed on day 7 of admission to determine the source of infection, showed a high signal surrounding the right wall, suggesting inflammation. Contrast-enhanced CT performed on day 1 of hospitalization revealed a low-density area in the same region; however, the pathological implications of this finding could not be determined. Based on DWIBS findings, we concluded that the condition presented as a myocardial abscess that was confined specifically to the right atrial wall. Three sets of blood cultures revealed negative findings, and echocardiography showed no vegetation or valve regurgitation. Therefore, the patient was diagnosed with an isolated myocardial abscess uncomplicated with IE. An electrocardiogram on admission showed no P waves, and the patient had a junctional rhythm. However, on day 20 of hospitalization, he developed a complete atrioventricular block. After complete myocardial abscess healing following antibiotic treatment was confirmed, the patient underwent pacemaker implantation. Ten months after surgery, the patient had no signs of infection recurrence. Conclusions Based on history and physical examination alone, diagnosis of an isolated myocardial abscess can be challenging. In addition to CT and echocardiography, DWIBS might be helpful for the diagnosis of myocardial abscesses.

“…Following a detailed literature research, it has been found in relation to septic foci such as decubitus ulcer, infected burns, bronchiectasis, and thrombophlebitis in patients with immunodeficiency. [ 7 ] Moreover, one case report demonstrated myocardial abscess at the site of infarcted myocardium. [ 8 ] None of the aforementioned conditions existed in our patient.…”

“…Intravascular devices make the patients susceptible to frequent transient bacteremia, particularly by S. aureus as the most common causative microorganism of IE in ESRD patients (2). On the other hand, extension of device-related infections to adjacent cardiac tissues is another mechanism underlying IE and subsequent myocardial abscess in populations undergoing HD (3). However, despite the high prevalence of vascular access-related infection, right-sided valvular IE is still unusual in patients undergoing HD (2).…”
