Show Hint
Three round vessels at the groin like a head with two ears mark the saphenofemoral junction.

- Mickey mouse sign
- String sign
- Tillaux sign
- Stemmer's sign
Show Solution
The Correct Option is A
Solution and Explanation
Shape recognition: Three round vessels arranged like a cartoon mouse head equal the Mickey Mouse sign.
On a transverse groin ultrasound just below the inguinal crease, the common femoral artery and common femoral vein form the round face and the great saphenous vein forms an ear, the classic Mickey Mouse silhouette. It is the go-to landmark for locating the saphenofemoral junction when scanning leg veins in chronic venous disease.
Option elimination: The string sign is the thread-like barium column of stenosed terminal ileum in Crohn's disease, not an ultrasound triad. Tillaux's sign describes a mesenteric cyst that moves freely in a line perpendicular to the root of the mesentery. Stemmer's sign is the bedside lymphoedema test where you cannot pinch the skin at the base of the second toe. None involve three round groin vessels, so Mickey Mouse sign is correct.
