Pulmonary lymphangiomyomatosis mimicking langerhans cell histiocytosis

The authors describe a patient with histologically confirmed pulmonary lymp hangiomyomatosis and thin-section computed tomography findings mimicking La ngerhans cell histioctytosis. The description emphasizes the nonspecificity of the computed tomography findings in this patient. This report also sugg ests that the computed tomography diagnosis of lymphangioleiomyomatosis can be difficult at an early stage of the disease and should be complemented b y biopsy verification.
