Spinal epidural abscess is an uncommon condition. Predisposing factors include spinal surgery, recent trauma, immunosuppression, a distal site of infection and intravenous drug use; however, these are not always present, as illustrated by this case report describing a patient who had repeated emergency department visits and delayed diagnosis that was ultimately confirmed via magnetic resonance imaging.

Modern air-nailing tools are known to cause penetrating trauma. We report the unusual case of a pneumatically fired carpenter's nail that penetrated the chest of a 30-year-old man and subsequently embolized from the heart to the left femoral artery without clinical evidence of having entered the heart. The nail was surgically removed, and the patient was discharged from hospital without sequelae after 10 days. This case and the relevant literature are discussed from the perspective of the emergency department investigation and care of such patients.
