Fig. 2. Brain magnetic resonance imaging of the same patient presented in Fig. 1. (A) FLAIR image illustrating sulcal hyperintensity in the left precentral gyrus, characteristic of SAH (arrow). This hyperintensity in the sulci indicates blood presence in the subarachnoid space. (B) Another FLAIR image illustrating a crescent-shaped hyperintense lesion along the left cerebral convexity, consistent with SDH (arrowheads). (C) SWI showing linear hypointensity in the precentral gyrus (arrow), supporting the presence of SAH by highlighting blood products. (D) SWI revealing hypointensity surrounding the hyperintense lesion in the left cerebral convexity seen on FLAIR (arrows), suggesting associated blood products with SDH. FLAIR, fluid-attenuated inversion recovery; SAH, subarachnoid hemorrhage; SDH, subdural hematoma; SWI, susceptibility-weighted imaging.
