Computed tomography of chylous effusion and congestion in lymphangioleiomyomatosis

(A) Axial section of a high resolution computed tomographic (HRCT) scan of the chest showing a right-sided chylothorax in a patient with lymphangioleiomyomatosis (LAM). Notice the characteristic cysts in the pulmonary parenchyma.
