22-month-old male with history of Langerhans cell histiocytosis involving the left temporal bone and T7 vertebra: end of therapy evaluation. Brain: There has no discernible evidence of residual lesion in the left temporal bone region. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma appears unremarkable. The ventricles and basal cisterns are stable in size and configuration. There is no midline shift or herniation. The paranasal sinuses are unremarkable. Spine: There is compression deformity and mild focal kyphosis at T7, although the vertebral body height has increased, now measuring a minimum of 4 mm in thickness centrally, previously approximately 2 mm. Furthermore, there is no significant spinal canal stenosis and no associated enhancement or edema. The other thoracic vertebrae are intact. The spinal cord and cauda equina nerve root signal is within normal limits. The paraspinal soft tissues are unremarkable.
1. No discernible evidence of residual or recurrent Langerhans cell histocytosis in the left temporal bone region.2. Mild interval increase in height of the T7 vertebral body associated with the treated Langerhans cell histocytosis.
