  • study comprises transverse non-contrast CT images of the thorax; lung window
  • multiple small pulmonary nodules, predominantly in the periphery
  • multiple pulmonary nodules is a non-specific finding; potential aetiologies include hematogenous dissemination of disease, e.g. metastasis, embolism
  • embolic pneumonia is compatible with the finding of sublumbar abscess
  • lumbar neoplasm with secondary abscess and pulmonary metastasis should also be considered
  • further testing may enable diagnosis of pulmonary lesions, e.g. bronchoalveolar lavage, biopsy
  • treatment of lumbar abscess may lead to resolution of embolic pneumonia without need for further testing; this could be determined by follow-up CT scan
