A 61 year old female presented to an outside hospital with increasing shortness of breath and cough. She complained of a non-productive cough for approximately six weeks.  She denied hemoptysis but complained of a low grade fever. Over this time she became progressively more short of breath. At the time of presentation she was able to only walk one hundred meters before she had to stop due to dyspnea.

Her past medical history included obesity, gastroesophageal reflux disease (GERD), peripheral vascular disease, hypertension, and type II diabetes. Family history was negative for lung cancer or chronic obstructive pulmonary disease (COPD). Her medications included aspirin, metoprolol, lisinopril, insulin glargine and esomeprazole. She denied any previous tobacco, alcohol or intravenous drug use. She was currently disabled due to chronic lower back pain.

Physical Exam

Her vital signs included a temperature of 101° F, respiratory rate of 28, blood pressure of 152/91 and heart rate of 99/min. Oximetry was 87% on room air. Physical exam revealed an obese female in mild respiratory distress. No accessory muscle use was noted. Right sided lung fields were clear. Left sided lung fields were clear posteriorly but diminished anteriorly. Cardiac exam was normal. No palpable lymphadenopathy was appreciated in the supraclavicular or axillary regions. The rest of the exam was unremarkable.


She presented to an outside hospital emergency department and was found to have an abnormal chest x-ray. Posterior-anterior (PA) and lateral films were provided (Figures 1 and 2).

Subsequently the patient underwent computed tomography (CT) of the chest with pulmonary angiography. Two cuts are provided below (Figures 3 and 4).

The patient was admitted to the outside hospital and underwent bronchoscopy for evaluation of left upper lobe (LUL) and lingular collapse. She was electively intubated for the procedure and bronchoscopy revealed an endobronchial lesion in the LUL. The patient was transferred on mechanical ventilation to a tertiary care center for further evaluation of suspected endobronchial malignancy. Repeat bronchoscopy was performed with results as shown in Video 1.

Bronchoscopy revealed a foreign body in the left upper lobe bronchus. Using cryotherapy, the foreign body was successfully removed and eventually identified as a popcorn kernel (Figure 5).
