Garland triad

Dr Henry Knipe and Dr Frank Gaillard et al.

Garland's triad (also known as the 1-2-3 sign or Pawnbrokers sign) is a lymph node enlargement pattern which has been described in sarcoidosis:

  1. right paratracheal nodes
  2. right hilar nodes
  3. left hilar nodes

Hilar lymphadenopathy is symmetrical and usually massive, so called ''potato nodes'', but do not usually abut the cardiac border which distinguishes it from lymphoma 3. Involvement of right paratracheal nodes is not magical but rather reflects the ease with which these nodes are identified on plain radiography. Left paratracheal and aortopulmonary nodes are also frequently enlarged, but harder to identify 1
