Fig.5From: Clinical and MRI features of sacral insufficiency fractures after radiotherapy in patients with cervical cancerBilateral SIFs had coexistent pubis fracture in a 63-year-old woman with cervical cancer after radiotherapy. A BS showed bilateral sacrum increased accumulation (white arrow) as an “H-sign”, and left pubis increased accumulation (red arrow). B Axial T1WI showed hypointensity. C Coronal FS-T2WI showed severe bone marrow edema. D Axial enhanced T1WI showed contrast enhancement in bilateral sacrum. E Axial enhanced T1WI showed enhancement with fracture lineBack to article page
