[A case of bronchogenic cyst coexisted with intrapulmonary and pleural cysts].

A 39-year old woman presented with cough. Computed tomography showed a mass in the lower lobe of the right lung. Although bronchofiberscope was performed, accurate diagnosis of the tumor was not obtained. Based on the characteristics of the tumor from the results of chest MRI and PET-CT, a diagnosis of bronchogenic cyst with infection was suspected. Therefore, surgical resection was performed, revealing an intrapulmonary bronchogenic cyst and another tumor of the pleura on the vertebral body. Pathological findings demonstrated that the wall of the intrapulmonary tumor was covered with many ciliated epithelia and bronchial cartilages, suggesting a diagnosis of bronchogenic cyst. The tumor on the pleura was also diagnosed to be bronchogenic cyst based on pathological findings. Therefore, we diagnosed both intrapulmonary and pleural cysts.
