    A nine year old boy with back pain is found to have a single lesion in a cervical vertebral body causing vertebral body flattening. These imaging features suggest suggest:

    a) Ankylosing Spondylitis

    b) Scheuermann Disease

    c) Enteropathic Arthritis

    d) Spondylolysis

    e) spondylolisthesis

    f) Neuroblastoma Congenital

    g) Osteoid Osteoma

    h) Histiocytosis X

    i) Tuberculosis

    j) Ewing Sarcoma

    h is the answer

    Histiocytosis X is seen in older children. Can present in vertebra with platyspondyly, so called vertebra plana. It\'s etiology unknown. It is a nondisseminated form of histiocytosis with localized proliferation of histiocytes. localized to the skeletal system. Good prognosis. There is an abnormal proliferation of histiocytes throughout the reticuloendothelial system. Imaging Findings: Usually monostotic. See a well defined intramedullary defect in tubular and flat bones without sclerosis around it and a circumferential cortical reaction without evidence of cortical destruction or soft tissue mass although if it gets big enough it can have sclerotic periosteal reaction around it. In the spine, it classically presents as vertebral body collapse (platyspondyly).

    keeping the age of pt and single level involvement causing back pain in view, Spondylolysis is the correct answer.
