| Summary: | The case is a 48-year-old female who presented with mild dyspnea on exertion and cough with unremarkable vital signs and was found to have a large right sided pneumothorax. She underwent small bore chest tube decompression with immediate reexpansion of the collapsed lung. However, she rapidly developed moderate hypoxemia and radiographic evidence of reexpansion pulmonary edema (REPE) on both the treated and contralateral sides. Within a week, she had a normal chest X-ray and was asymptomatic. This case describes a rare complication of spontaneous pneumothorax and highlights the lack of correlation between symptoms, sequelae, and radiographic severity of pneumothorax and reexpansion pulmonary edema. Proposed pathophysiologic mechanisms include increased production of reactive oxygen species with subsequent loss of surfactant and increased vascular permeability, and loss of vasoregulatory tone. |
