Pleural chylous effusion

Chylothorax is rarely reported (21-23). The low incidence of chylous effusions despite the frequent appearance of mediastinal and hilar adenopathy in AL amyloidosis raises the possibility that direct amyloid infiltration of pleural lymphatics causes chylous effusions, not lymph node compression of mediastinal lymphatics. 

Respiratory Chylous pleural effusions have been reported in two adults who received parenteral nutrition delivered via peripherally inserted central catheters [19 ]. 

No nodules, linear lines, or irregular pleural-parenchymal interfaces Ground glass opacities (12-59%) but not dominant feature Pleural effusions (chylous) (21-39%)...
