It's a leak in the network of vessels that look like a spiderweb-hence the name-arachnoid.

Because the vessels are so small and wide spread, docs can get a general idea of where the hemorrhage is located, but they have to pinpoint the exact area of the rupture before they can open up the skull to repair it.

Not a good thing.
When I was working in Neuro ICU, we had a gal in her 40's with an SAH due to an aneurysm. They did an Angio and found FIVE more aneurysms scattered in her brain. Only one had bled, so they clipped that one and two others that were close. The plan was to bring her back in a year and clip the others. She was one of the lucky ones - no deficits.
