The aims of this paper are, on one hand, to communicate the clinical case of a 73-year-old osteoporotic woman with traumatic vertebral fractures who developed this sign in her radiological survey. The broad diagnosis is made by antero-posterior X-ray, but computed tomography scan (CT scan) and magnetic resonance imaging (MRI) may help with the differential diagnosis. Post-traumatic ischemic necrosis could be its physiopathological mechanism, along with other pathologies like osteoporosis, corticosteroid therapy, diabetes, arteriosclerosis, alcoholism, multiple myeloma, bone metastasis and osteomyelitis.
