Cystic versus Reticular It can be difficult to determine whether we are dealing with a reticular pattern or a cystic pattern. The CXR is of a patient with Langerhans cell histiocytosis (LCH). LCH is called a cystic disease. On the CXR it is difficult to see if this is a cystic or a reticular pattern. In many of such cases a HRCT will give you more information. #Clinical #Radiology #CXR #CTChest #Cystic #Interstitial #Langerhans #LangerhansCellHistiocytosis #LCH #RadiologyAssistant
