Signs in X-ray –
v WATER LILY SIGN - Seen in "lung hydatid cyst"-due to rupture
of the endocyst makes thescolices and broods capsule float in the hydatid fluid
with the ecto andpericyst intact
v MENISCUS (HALO SIGN) - Seen in any "cavity filled with opaque masses"
(fungal ball, blood clots,etc.) due to masses filling almost the entire cavity
leaving only a thin rimin the periphery
v FLESCHNEIRS SIGN - Seen in conditions wherein right dome of the
diaphragm is chronicallyelevated. And the tidal volume in the right lung is
reduced forming linearplate 'atelectasis'. Seen best in the "right lung
bases".
v FELSONS (SILHOUTTE) - Seen in "any lung opacity" that has the
same increased density as theadjoining mediastinal structure.For e.g.
consolidation of the right middlelobe and the adjacent cardiac border have the
same density and hence thecardiac border (silhoutte ) is masked.
v GOLDENS S-SIGN - Seen in "central bronchogenic lung
carcinoma" –due to right hilar masscompressing the medial end of the minor
fissure downwards and the lateral end is elevated upwards to form the
letter S sign
v 3- SIGN - Seen in coarctaton of descending aorta due to dilatation of
the aortaimmediately proximal and distal to the "coarcted" segment.
v UPTURNED MOUSTACHE SIGN - Seen in "rheumatic mitral stenosis"
with chronic pulmonary venouscongestion due to upper lobevessels being dilated
and redistributed
v BATS-WING SIGN - Seen in "pulmonary odema" due to ground
glass opacity from bilateralalveolar odema spreading and fanning out from the
both the hila.
v GARLANDS SIGN - Seen in ''lung sarciodosis'' due to bilateral
symmetrical hilarlymphadenopathy. With later on show the typical egg shell
calcification.
v TRAM LINE SIGN - Seen in "chronic bronchitis" due to
hypertrophied mucosal goblets cell withair trapped in the middle of the lumen
