History (HX): Sudden severe headache + nausea & vomiting
Findings: Axial FLAIR : High signal intensity within the cerebral Representing (SAH) sulci Axial T2WI: A small rounded flow void adjacent to the circle of willis (consistent with the aneurysm) Diagnostic (DX):SAH due to ruptured aneurysm (Right ICA ) Discussion :Conventional MRI with FLAIR sequence has high sensitivity and is a reliable imaging technique for acute SAH, but detection of abnormal increased signal intensity within the cortical sulci on FLAIR images is nonspecific in terms of differentiating subarachnoid space diseases related to blood , inflammation or tumor. Contrast enhanced MRI and MRA should be done at next steps. |
