Super-selective cerebral angiography mimicking subarachnoid hemorrhage: Revisited by an old demon with a different mask!

The article discusses a case study of a patient who experienced subarachnoid hemorrhage (SAH) after undergoing super-selective cerebral angiography (SSCA). The patient had an anterior communicating artery (Acom) aneurysm, which was treated with a Woven Endo Bridge (WEB) device. However, after the procedure, the patient developed aphasia and showed signs of SAH on imaging. The article explores various possible causes for the SAH, including rupture of the embolized aneurysm, lenticulostriate aneurysm, vessel perforation, contrast-induced SAH, and iatrogenic SAH. The authors conclude that the most likely cause was iatrogenic SAH with parenchymal enhancement induced by contrast injection into the smaller M2 segment of the middle cerebral artery (MCA).
