[Radiologic appearance of primary anomalies of the lymphatic vessel system of the lung. Review and personal results].
Congenital disorders of the lymphatics of the lung are rare. On the basis of a literature review and our own experiences the disorders are divided into four groups and their radiographic findings are described. Pulmonary lymphangiectasia shows not typical signs. As an expression of the underlying pathophysiologic processes CT shows thickening of interlobular septs, interstitial edema and pleural effusions. Neither architectural distraction nor thickening of intralobular septs was seen. Lymphangioleiomyomatosis shows rather typical findings with multiple thin-walled bullae. In contrast to the opinion that architectural distraction is not seen in LAM we sometimes found signs of fibrosis. Disseminated pulmonary lymphangioma is characterised by proliferation of lymph vessels. CT-findings of this disorder have not been described before. CT shows multiple disseminated nodules of up to 2.5 cm accompanied by multiple bullae of similar distribution and size.
