Giant pulmonary cyst in extremely low birth weight (ELBW) infants has been described as one of severe pulmonary diseases. Any definitive therapy for refractory cases, where conservative methods of treatments are not effective, has not been established as a standard. Herein, we report an ELBW infant with a giant pulmonary cyst cured by percutaneous drainage without any adverse events. A female infant was born with a birth weight of 327 g. Surfactant was administered on days 1 and 2 of life to treat respiratory distress syndrome. Tracheal intubation was performed and synchronized intermittent mandatory ventilation was promptly initiated following birth. On the course, right giant pulmonary cyst developed on day 9 after birth. Although we started conservative therapy, including right lateral decubitus positioning, high-frequency oscillatory ventilation, and systemic corticosteroid administration, the diameter of the cyst had reached 34 mm, and mediastinal displacement was observed on day 28 after birth when she weighed 393 g. She recovered by percutaneous drainage followed by suction with a pressure of -10 cm H O under mild sedation for 3 days. We believe that percutaneous drainage can be one of the available options for unilateral pulmonary interstitial emphysema.
