RESUMO
The kidneys are the most commonly injured genitourinary organ in children following blunt abdominal trauma. Though the retroperitoneal location affords the kidneys some protection from the forces experienced in blunt abdominal trauma, the kidneys are at greater risk of injury when a disease process exposes them from their normal shielded location. In such cases, the injuries may appear to be disproportionate in relation to the severity of the trauma history, confusing the imaging findings. Recognition of both the underlying disease process as well as the manifestations of acute trauma is important; therefore, we present a pictorial essay of traumatized kidneys in children with pre-existing renal abnormalities.

Osteoid osteoma is an uncommon, benign disorder of bone that is most often encountered in school-age children and in adolescents. It is quite rare in children under the age of 3 years. We report a case of osteoid osteoma with unusual clinical and imaging features in a 27-month-old toddler who presented with a limp and swelling of the right knee. Initial clinical evaluation, plain films, and computed tomography (CT) were strongly suggestive of chronic osteomyelitis involving the distal right femoral metadiaphysis. The appearance on nuclear medicine bone scan, however, was typical of osteoid osteoma. A biopsy of the lesion was taken and histological examination confirmed the diagnosis of osteoid osteoma. The misleading clinical and imaging features in this case are discussed.
