Overview

There are no CT scan findings associated with hepatopulmonary syndrome.

OR

[Location] CT scan may be helpful in the diagnosis of hepatopulmonary syndrome. Findings on CT scan suggestive of/diagnostic of hepatopulmonary syndrome include [finding 1], [finding 2], and [finding 3].

OR

There are no CT scan findings associated with hepatopulmonary syndrome. However, a CT scan may be helpful in the diagnosis of complications of hepatopulmonary syndrome, which include [complication 1], [complication 2], and [complication 3].

CT scan

Chest CT scan and particularly high resolution ct scan (HRCT) may be helpful in the diagnosis of hepatopulmonary syndrome. Although, CT Scan studies are frequently nonspecific and subtle. Findings on CT scan suggestive of of hepatopulmonary syndrome include:

• Dilated peripheral pulmonary vessels
• Increased pulmonary artery to bronchus ratios
• Characteristic findings of intrapulmonary vascular dilatations
• Direct arterio-venous communications may be less commonly seen.

• We should keep in mind that Ct scan is often unremarkable in patients with hepatopulmonary syndrome, and hence a a normal radiograph (either CXR or CT Scan) does not rule out hepatopulmonary syndrome.
