Question:

Which of the following is not an imaging sign of hydatid disease?
1. Snow storm.
2. Floating membrane.
3. Floating Water lily.
4. Ball of wool.
5. Drooping lily.





Answer:

The correct answer for the question "Which of the following is not an imaging sign of hydatid disease?" is:

5. Drooping lily.



Explanation
"[On US, the hydatid cyst typically shows thick concentric walls. Multiple echogenic foci due to hydatid sand render a `snow storm` appearance. The endocyst may detach from the pericyst causing `floating membranes` inside the cavity, which is highly specific for hydatid disease. Complete detachment has been referred to as the "floating water lily sign". The folded membranes in a treated hydatid cyst have also been named as `ball of wool` or `yarn sign` or `spin/whirl` sign]"

1. Snow storm [this appearance is seen on US, as multiple echogenic foci due to hydatid sand].

2. Floating membrane [endocyst when detach from the pericyst is seen as `floating membranes` inside the cavity, which is highly specific for hydatid disease and can be demonstrated both on US & MRI].

3. Floating Water lily [complete detachment of the endocyst from pericyst gives the appearance of a floating water lily in both US & MRI].

4. Ball of wool [in treated hydatid cyst, the detached endocyst get folded and is often called as `ball of wool` or `yarn sign` or `spin/whirl` sign].   

5. Drooping lily [`drooping lily sign` is identified at excretory urography in patients with duplicated renal collecting systems].

Abstract
The present article reports a case of a 21 years male that was diagnosed to have isolated intramuscular hydatid cyst of the biceps brachii on Ultrasound and MRI. The `Scroll appearance` of the ruptured endocyst in this case is likely to be an intervening transient stage in evolution of the disease and also indicates recent rupture of the endocyst.
