Question:

What are common brain MRI findings of hepatic disease:
1. Basal ganglia T1 hyperintensity
2. Basal ganglia calcifications
3. Diffuse cerebral edema
4. Edema in the white matter and corticospinal tracts
5. A, C and D





Answer:

The correct answer for the question "What are common brain MRI findings of hepatic disease:" is:

5. A, C and D



Explanation
a. Basal ganglia T1 hyperintensity. ["Another common radiological finding in hepatic encephalopathy is hyperintense signal in the globus pallidi, putamen and internal capsules on MRI T1-weighted images"]b. Basal ganglia calcifications are not specifically related to hepatic disease.c. Diffuse cerebral edema. ["Previously described cerebral abnormalities associated with hepatic encephalopathy include edema…"]d. Edema in the white matter and corticospinal tracts. ["MRI studies in patients with hepatic encephalopathy have also shown signs of edema in the white matter and cortico-spinal tracts."]e. A, B and C [see above explanations]

Abstract
We report a new radiological finding in two patients with hepatic encephalopathy. A new susceptibility-weighted (SWI) magnetic resonance imaging sequence revealed multiple bilateral microsusceptibility changes in the corpus callosum and white matter, while the conventional T1 and T2 weighted images were unremarkable. We postulate that the etiology of the microsusceptibility changes may be related to hepatic coagulopathy and other factors, such as impaired cerebral blood flow and brain edema.
