Foreign body in bladder

Here is a disturbing account in the New England Journal of Medicine about a bi polar woman who tried to put a nail in her uterus to deter rape.

I wonder if they ever followed up on the hypodense area in her head. They only mention sending her to the psych ward after she "painlessly" passed the nail (!). I can only imagine how out of touch someone would be if they had severe bi polar and a brain tumor. It's rather terrifying.
