There is diffuse cystic lung disease where the cysts are round, thin walled and there is minimal septal thickening. The plain radiograph shows bilateral pleural fluid collections which were chylous. A coil is seen in the throcic duct from an attempt to reduce the recurrent lymphatic leak. These findings are consistent with lymphangioleimyomatosis (LAM). The CT also shows a right pneumothorax and small bilateral chylothorax two complications of LAM.
