RESUMO
We report a case of multifocal osteosarcoma in a 7-year-old boy who developed iatrogenic seeding of tumor along the biopsy tract. The results of the plain radiograph, CT, and histopathological correlation are presented.

We report a 21-month-old boy with multiple contiguous thoracic vertebral compression fractures involving eight vertebral bodies, attributable to non-accidental injury. No subluxation was associated, however, there was extensive injury to the upper cervical and lower lumbar regions of the spinal cord. Anterosuperior beaking, thought to represent a previous injury, was evident in a mid-lumbar vertebra. Clinical examination revealed bilateral retinal hemorrhages and retinoschisis. Death occurred as a result of severe brain edema with bilateral subdural and subarachnoid hemorrhages. Radiological-pathological correlation is presented.

OBJECTIVE: The purpose of this study was to describe the radiographic features and etiology of the "diaphanous" (translucent) diaphragm. This sign, which, to our knowledge, has not previously been described, is a transient phenomenon seen on chest radiographs, after surgical patch repair of congenital diaphragmatic hernia. CONCLUSION: The diaphanous diaphragm is a consequence of air trapped in the porous polytetrafluoroethylene graft that creates an intragraft radiolucency apparent on postoperative chest radiographs obtained within the first 24 hr. This radiolucency is transient and gradually disappears over the first few postoperative days as the air is replaced by granulation tissue. This sign should be recognized and not mistaken for a persistent pneumothorax after repair of a congenital diaphragmatic hernia.
