Mickey Mouse sign is a
medical sign resembling the head of
Mickey Mouse, the
Walt Disney character. Presented for the very first time at the CHIVA's Meeting, Berlin 2002 by Dr. Lurdes Cerol,[citation needed] this sign has been described as the image at the
groin when a dilated
accessory saphenous vein (ASV) exists: the
common femoral vein (CFV) represents the head of Mickey Mouse while the
great saphenous vein (GSV) and the dilated
accessory saphenous vein (ASV) represent the ears. The presence of a Mickey Mouse sign has been a great diagnostic clue to check ASV insufficiency.

Dysmorphic Mickey Mouse RBCs:
RBCs with irregular cell walls and migration of
hemoglobin into some areas creating the shape of Mickey Mouse ears.[6] The presence of these dysmorphic cells in
urine may indicate
intraglomerularhaemorrhage.[7]
