A 37-year-old woman with no relevant disease history was admitted to our Intensive Care Unit with a diagnosis of spontaneous subarachnoid hemorrhage (SAH) (Hunt-Hess II, Fisher IV). She suddenly suffered a decrease in consciousness to 3 points on the Glasgow coma score, with bilateral nonreactive mydriasis. A new tomographic exploration was immediately performed, including angioCT, revealing hyperacute repeat bleeding (see arrows numbered as 2, Fig. 1) originating from an aneurysm (see arrows numbered as 1, Fig. 1) dependent upon the anterior communicating artery (ACoA). Emergent neurosurgery was performed, with attempted surgical clipping, though without success. The patient unfortunately died as a result of brain death.
