Perilymphatic distribution Perilymphatic nodules are most commonly seen in sarcoidosis. They also occur in silicosis, coal-worker's pneumoconiosis and lymphangitic spread of carcinoma. Notice the overlap in differential diagnosis of perilymphatic nodules and the nodular septal thickening in the reticular pattern. Sometimes the term reticulonodular is used. #Diagnosis #Radiology #Pulmonary #HRCT #CTChest #Perilymphatic #Nodular #Differential #RadiologyAssistant
