Background cystic lung disease in keeping with the history of lymphangioleiomyomatosis (LAM). A left anterior intercostal pigtail catheter is positioned in the left pleural space anteriorly. Small residual pneumothorax within the left lateral costophrenic angle.
The previously demonstrated 16 mm nodule within the left upper lobe remains similar in size and morphology to the previous examination from one year prior. Stable left-sided pleural thickening is also again noted.
No destructive bony abnormality identified. Innumerable renal angiomyolipomas
also again noted in keeping with the history of tuberous sclerosis (TS).
