ANSWERS AND EXPLANATIONS

---

A) This space is part of the reason this patient died

This answer is incorrect.

The unnecessarily large red arrow is pointing to a Virchow-Robin space. Virchow-Robin spaces are normal spaces, sometimes visible on MRI, which are lined with pia and are extensions of the subarachnoid space. These spaces continue along arteries, but are not found around capillaries.  (See References)

E) This is a pocket of gas created by bacteria post-mortem

This answer is incorrect.

Pockets of gas, created by bacteria if the body remains unfixed for too long post-mortem, do sometimes occur. This creates the artifact called "swiss cheese brain."

However, this space is a normal space, not an artifact.
