[High-resolution computed tomography of the thorax in lymphangioleiomyomatosis and tuberous sclerosis].

We present three cases that illustrate the HRCT appearance of pulmonary lymphangioleiomyomatosis and pulmonary involvement in tuberous sclerosis. All patients had multiple cystic lesions diffusely distributed throughout the lungs. The lack of fibrotic changes was a prominent feature in all patients. HRCT correlated more closely than conventional CT with the pathologic findings.
