Question:

Imaging findings suggestive of celiac artery dissection include?
1. intimal flap
2. mural thrombus
3. infiltration of fat around celiac artery
4. all of the above
5. none of the above





Answer:

The correct answers for the question "Imaging findings suggestive of celiac artery dissection include?" are:

1. intimal flap

2. mural thrombus

3. infiltration of fat around celiac artery

4. all of the above



Explanation
1: intimal flap (Intimal flap is diagnostic sign of dissection)

2: mural thrombus (Mural thrombus is seen in a dissection if thrombus forms in the dissection and should raise a suspicion for dissection)

3: infiltration of fat around celiac artery (Infiltration of the fat surrounding the celiac axis may be seen in acute spontaneous celiac artery dissection. This finding may be predictive of the acuity of dissection and predisposition toward extension of dissection into adjacent vessels as suggested by D`Ambrosio et al.)

4:  all of the above (Diagnostic imaging findings on CT according to Kim et al include an intimal flap, which is pathognomonic or eccentric mural thrombus in the celiac lumen, which should raise suspicion for dissection (8). Because the intimal flap is not always visible, mural thrombus may be the only clue to the presence of dissection (4, 8). Infiltration of the fat surrounding the celiac axis may be seen in acute spontaneous celiac artery dissection. This finding may be predictive of the acuity of dissection and predisposition toward extension of dissection into adjacent vessels as suggested by D`Ambrosio et al)

5: none of the above (Intimal flap, mural thrombus and infiltration of fat around the celiac artery are some of the findings seen in dissection of the celiac artery.)

Abstract
Spontaneous visceral artery dissection is an uncommon event with an unpredictable natural history with superior mesenteric artery being the most common affected artery. It is most often asymptomatic and usually diagnosed at autopsy. Pre-disposing factors are not specific but have been suggested to be pre-existing vascular disease, hypertension and pregnancy. Spontaneous resolution, definitive occlusion of the artery, and formation of an aneurysm with associated complications are some other possible outcomes. Isolated dissection of the celiac artery (CA) is rare and there are only a few cases reported in the literature. We present a case of a 65 year old male with spontaneous celiac artery dissection and provide a review of the current literature about imaging findings and management of this entity.
