An Unusual Case of Needle Embolus Presenting With Delayed Spontaneous Pneumothorax

We report the case of a 39-year-old man presenting with an acute right-sided traumatic pneumothorax secondary to migration of a hypodermic needle fractured during intravenous drug use. We discuss the unusual passage of this foreign body from the left groin to the right ventricular wall and into the mediastinum, ultimately presenting with a right pneumothorax 1 year later.
