Variably Sized
Chronic Pulmonary Langerhans Cell Histiocytosis (PLCH)
CT Sagittal Plane  Multiple Thin Walled Cysts Upper Lobe
54 year old smoker presents with a chronic cough.   CT in the sagittal plane shows multiple thin walled cysts of varying size with upper lung predominance.  
Findings are consistent with chronic pulmonary Langerhans cell histiocytosis (PLCH)

CT Coronal Multiple Thin Walled Cysts Upper Lobe
54 year old smoker presents with a chronic cough.   CT in the coronal plane shows multiple thin walled cysts of varying size with upper lung predominance.  The cysts appear to be aligned with a normal sized subsegmental airway with minimal wall thickening (ringed in white lower image) 
Findings are consistent with chronic pulmonary Langerhans cell histiocytosis (PLCH)

CT Chest – Cavitating Metastatic Trophoblastic Tumor
28year old female presents with vaginal bleeding for 3 days s/p ablation of a vascular molar pregnancy.  CT of the chest shows multiple cystic lesions in the lungs bilaterally with slightly thickened walls.  Wedge biopsy confirmed a diagnosis of  placental site trophoblastic tumor

LAM and LYMPHANGIOLEIOMYOMAS in the ABDOMEN
38-year-old patient with progressive dyspnea and cough
CXR (scout for CT) shows hyperinflated lungs with increased lung volumes with bilateral and extensive thin-walled cysts surrounded by very little normal lung parenchyma. The cysts are round and thin-walled except for air filled large irregular pocket in the right apex (image 27628/29) . Some of the cysts do not have walls at all and others have an irregular configuration.
In the abdomen multiple low density lymphangioleiomyomas are present that are due to lymphatic obstruction.
