ANSWERS AND EXPLANATIONS




A) Granulation tissue

This answer is correct.


Granulation tissue is composed of fibroblast and immature capillaries, which allow intravenous contrast to escape into the tissue.  (See References)

D) Collagen

This answer is incorrect.


Once granulation tissue has matured into collagen, the blood vessels have developed tight junctions, and no longer leak contrast  (See References)

E) Astrocytosis

This answer is incorrect.


The astrocytic reaction to cerebral abscess does not include development of leaky blood vessels, and hence the reactive astrocytosis around the cerebral abscess does not demonstrate contrast enhancement.  (See References)
