Asimagingmodalities have evolved, so has our understanding of intrathoracic metastatic patterns and their impact on patient management. We reviewthoraciclymphatic pathways and tributaries, discuss anatomic variations in the lymphatic system and their implications for metastatic spread, and emphasize common patterns ofthoraciclymphadenopathy that may predict the primary tumor origin ...
In this article, we discussthoraciclymphatic anatomy,imagingmodalities for lymphatic abnormalities, causes ofthoraciclymphatic disruption,imagingmanifestations of lymphatic abnormalities in the various anatomic compartments, and interventional radiology treatment of chylothorax.
However, our network analysis revealed different patterns oflymphnodemetastases according to the location of the primary tumor, supporting a need for clinical trials to investigate selective mediastinallymphnodedissection. Lung cancer often metastasizes to regionallymphnodessuch as to the parenchymal, hilar, or mediastinallymphnodes.
Lymphnodemetastases in the chest from boththoracicand extrathoracic malignancies usually follow typical or common pathways of drainage. 4-6 Computed tomography (CT) is the primaryimagingmodality for the evaluation of intrathoraciclymphnodesand the lymphatic system.
The efferent lymphatics of thesenodes, in turn, extend to the left and right mediastinallymphtrunks, potentially draining into thethoracicduct or directly into the ipsilateral brachiocephalic ...
To summarize existing evidence ofthoracicmagnetic resonance (MR)imagingin determining the nodal status of non-small cell lung cancer (NSCLC) with the aim of elucidating its diagnostic value on a per-patient basis (eg, in treatment decision making) and a per-nodebasis (eg, in target volume delineation for radiation therapy), with results of cytologic and/or histologic examination as the ...
