A 20-year-old man with a past medical history of hereditary multiple osteochondromas (HMO) presented with a one-day history of persistent chest pain exacerbated by deep inspiration and exertion. His physical exam was significant for multiple palpable bony masses of the appendicular skeleton. Initial EKG showed a diffuse ST elevation pattern consistent with acute pericarditis, and pertinent lab findings demonstrated elevated troponin, erythrocyte sedimentation rate, C-reactive protein, and D-dimer. A computed tomography (CT) scan revealed a bony mass extending from the posterior aspect of the left fourth rib and abutting the pericardium (Figure 1).  Echocardiogram revealed the same and demonstrated a normal ejection fraction and no pericardial effusion.  Resection of the chest wall bony mass with partial fourth rib resection was performed by video-assisted thoracoscopy (Figure 2).  Pathology confirmed osteochrondroma.
