Images of a 48-year-old male patient who presented with transient loss of consciousness and acute headache for 6 h. a Computed tomography angiography (CTA) showed that the M1 segment was slightly swollen at the end, which was not obvious (see arrow). This patient was diagnosed as normal at the time of admission. b Computed tomography (CT) showing the subarachnoid hemorrhage of the patient; c-d 1 month later, diffusion-weighted imaging (DWI) and susceptibility weighted imaging (SWI) showing saccular aneurysm; e magnetic resonance angiography (MRA) showing an aneurysm at the M1 segment (see arrow); and f-h high-resolution magnetic resonance imaging (HRMR-VWI) showing aneurysmal protrusion with thickened residual wall at the end of the M1 segment and a crescent-shaped hematoma under the tunica adventitia (see arrow)
