Question:

Regarding imaging in portal and systemic venous gas, select the correct sentence:
1. Portal gas appears as linear hyperdensities in computed tomography
2. Systemic venous gas has unique features in ultrasound
3. Gas within the small mesenteric vessels is not detected by computed tomography
4. Systemic venous gas will appear as peripheral ring of gas in computed tomography
5. Combined portal and systemic venous gas is a rare radiological finding





Answer:

The correct answer for the question "Regarding imaging in portal and systemic venous gas, select the correct sentence:" is:

5. Combined portal and systemic venous gas is a rare radiological finding



Explanation
a. [The Computed tomography findings of portal gas is described as branching hypodensities]
b. [On ultrasound, any intravascular gas can be easily identified in the lumen of the vessel as small mobile echogenic foci]
c. [Gas in the small mesenteric veins appears as tubular or branched areas of decreased attenuation in the mesenteric border of the bowel]
d. [The systemic venous gas in CT imaging appears as a gas fluid level in axial sections]
e. [Combined portal and systemic venous gas has been described in literature in six cases]

Abstract
Gas within the portal circulation has been known to be associated with a number of conditions most commonly mesenteric ischemia and necrosis. Systemic venous gas is described with few conditions and is mostly iatrogenic in nature. We describe a case of combined portal and systemic venous gas detected by computed tomography in a patient with perforated duodenal ulcer.
