A very rare thing.  And not a very hard preop embolization (for repeat hemorrhage from pseudoaneurysm) with nBCA — here diluted heavily with Lipidol (1:4 nBCA::Lipidol — to conserve expensive nBCA).  The majority of embo — and the vast majority of nidal penetration part — was done by direct access with live subtraction injection visualization by Dr. Eytan Raz.  It is very highly effective and straightforward in this location.

Anaglyph stereos. The pseudoaneurysm can be seen on lateral projections.

Major supply comes from posterior auricular artery, with minor contribution from the STA.
