Shortness of breath: Patient history not always indicative of the cause

This is a 78 year old male with a past medical history of coronary artery disease (CAD), chronic obstructive pulmonary disease (COPD), hypertension (HTN), and gastroesophageal reflux disorder (GERD) who presented to the emergency room with worsening shortness of breath (SOB) and low-grade fevers for one week prior to admission. He was originally diagnosed with healthcare associated pneumonia (HCAP) and an acute on chronic COPD exacerbation and treated with prednisone, inhalers, ipratropium/albuterol, and broad-spectrum antibiotics. His symptoms were slow to respond to therapy and he continued to have end-expiratory wheezes with persistent SOB. A CT of his chest was ordered to rule out a possible pulmonary embolus (PE) and instead showed an obstructing mass in the bronchus. Pulmonology was consulted and performed a bronchoscopy, which revealed a foreign body (bean) causing the obstruction, which was removed, and the patient's symptoms improved shortly thereafter.
