The patient sustained a minor spinal trauma, and their spine X\u2010ray examinations were negative. However, after an asymptomatic period of months, they developed recurrent back pain because of the progressive vertebral collapse of the affected spine. However, no imaging examination could confirm the magnetic resonance imaging (MRI)\u2010negative initial spinal trauma followed by delayed vertebral collapse with IVC.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case Presentation<\/jats:title><jats:p>We report a case of KD occurring in a 66\u2010year\u2010old postmenopausal patient whose lumbar MRI on sagittal planes were immediately performed following the initial trauma (a ground\u2010level fall) and revealed that the vertebral integrity or connectivity was not interrupted and the marrow signal was even. After an asymptomatic period of 8\u2009months, the back pain reappeared and progressively exacerbated. The wedge\u2010shaped change in the T11 vertebra with an IVC was confirmed by lumbar computed tomography and MRI. Finally, KD was diagnosed following extensive routine hematological and biochemical workups. Percutaneous kyphoplasty was performed to relieve her back pain by restoring her vertebral stability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>We confirmed that the
