BACKGROUND: Purulent pericarditis is rare, typically affecting immunocompromised individuals from hematogenous spread, contiguous extension, or direct inoculation. Esophageal foreign body migration as an etiology has not been previously described. CASE SUMMARY: A 42-year-old immunocompetent male presented with pleuritic chest pain and dysphagia after ingestion of a tripe burrito. He developed hemodynamic instability from cardiac tamponade. Emergent pericardiocentesis was performed, yielding fluid that grew Streptococcus constellatus. Computed tomography and esophagogastroduodenoscopy identified a penetrating foreign body in the distal esophagus. He improved following video-assisted pericardial washout and antibiotic therapy. Follow-up imaging demonstrated migration of the object between the thoracic aorta and azygos vein. DISCUSSION: Rare cases of purulent pericarditis in immunocompetent patients have been reported via respiratory translocation; however, this appears to be the first reported case of purulent pericarditis due to esophageal foreign body migration. Multidisciplinary consensus supported conservative management rather than surgical pericardiectomy and led to a full recovery. TAKE-HOME MESSAGES: Early recognition of purulent cardiac tamponade due to foreign body ingestion, along with prompt pericardiocentesis and antibiotic therapy, was critical for stabilization and individualized management.
