Garland triad, also known as the 1-2-3 sign or Pawnbrokers sign, is a lymph node enlargement pattern on chest radiographs which has been described in sarcoidosis:
- right paratracheal nodes
- right hilar nodes
- left hilar nodes
Hilar lymphadenopathy is symmetrical and usually massive. These so-called potato nodes typically do not abut the cardiac border which distinguishes it from lymphoma 3.
Involvement of right paratracheal nodes reflects the ease with which these nodes are identified on plain radiography.
Left paratracheal and aortopulmonary nodes are frequently enlarged but harder to identify 1.
