Thoracic-abdominal MDCT: A one-stop-shop procedure for diagnosis of lymphangioleiomyomatosis

Abstract

A 62-year-old asymptomatic woman was referred for an abdominal multidetector CT (MDCT) scan to evaluate a renal angyomiolipoma. Upper MDCT images revealed multiple, bilateral pulmonary cystic lesion in the costo-phrenic sulci and a thin-section MDCT scan of the chest was consequently performed. Thin-section MDCT showed several thin-walled cysts uniformly distributed throughout the lung parenchyma consistent with lymphangioleiomyomatosis (LAM). This radiological approach secured a definite diagnosis of LAM, thus avoiding further invasive procedures.
