Abstract
A 93-year-old man presented with a soft, nontender swelling on his right anterior chest wall near his pacemaker pocket site (Figure 1). He denied other symptoms and was systemically well and afebrile. The patient had multiple comorbidities, including chronic renal impairment, ischemic heart disease, paroxysmal atrial fibrillation, vascular dementia, hypertension, previous subclavian venous thromboses, and polymyalgia rheumatica, for which he was receiving long-term steroids. Ultrasonography of the swelling confirmed a fluid-filled collection at the site of his pacemaker pocket, without a vascular communication between the pocket and subclavian vein (Figure 2). Inflammatory marker (C-reactive protein, leukocytes) and blood culture results were negative. Two hundred millilitres of purulence was drained from the pocket.
