Why could this not be extravascular hemolysis? In FA it says acute hemolytic transfusion reaction can be due to ABO incompatibility or extravascular hemolysis.

niboonsh  because extravascular hemolysis is associated w jaundice. Intravascular hemolysis would have hemoglobinuria but that's not an answer
niboonsh  i mean that is the answer lol

The patient has a leaking berry aneurysm --> this leads to a subarachnoid hemorrhage (or leakage into subarachnoid space) --> acute SAH can lead to decreased absorption and movement via arachnoid villi

zbird  So this patient has a leaking berry aneurysm which undergone to surgery and repaired but in two days she developed widening of the SA space which could be explained by increased CSF production but a decreased in absorption, which is due to blockage of the arachinoid granulations by the leaked red and white cells therefore there is a decreased movement of the CSF via the arachinoid villi

"Desmosome (Macula adherens) - A cell-to-cell connection that provides structural support with intermediate filaments, particularly in tissues that undergo mechanical stress (e.g., skin, gastric tissue, bladder). Connects keratinocytes in the stratum spinosum of the epidermis." - AMBOSS

sympathetikey  This is why I was looking for some answer indicating keratinocytes in the stratum spinosum...instead they just gave a bunch of bs choices. +6  
roygbiv  I'm confused because I also know that S. aureus cleaves desmoglein in the stratum granulosum, so why is it specifically this answer? +  
duat98  desomosomes connects cells to cells. hemidesmosome connects cells to basement membrane. +
