Pulmonary lymphangioleiomyomatosis.

This paper reports a case of a 50 yr old premenopausal woman with pulmonary lymphangioleiomyomatosis. This asymptomatic woman was found to have 'pulmonary nodules' on routine chest x-ray simulating metastatic lesions. The final diagnosis was possible after pathological examination of the lung biopsy specimens. This case is atypical for 3 reasons: firstly, the patient's age was 50, unusually old for this tumor; secondly, she was asymptomatic; and finally, the pulmonary imaging findings revealed bilateral nodular lesions in contrast to the usual reticular pattern.
