Incidental osseous lesions on chest CT: an algorithmic approach for radiologists

      Highlights

      • Describe common osseous lesions encountered in daily practice at chest CT.
      • Familiarity with a systematic, algorithmic approach to osseous lesions on chest CT
      • List worrisome imaging features that require further evaluations for each type of lesions
      • Identify the correct management strategy and the best imaging modality as the next step

      Abstract

      Numerous osseous findings are commonly discovered incidentally at chest CTs in daily practice. A broad spectrum of these findings ranges from benign and do not touch lesions to ominous conditions requiring further imaging evaluation and/or intervention. Interpretation of these incidental musculoskeletal findings may constitute a diagnostic challenge to radiologists. This review provides a systematic, algorithmic approach to common osseous lesions on chest CT based on imaging findings with recommendations for proper next step management.

      Abbreviations:

      CT (computed tomography), PET (positron emission tomography), FDG (fluorodeoxyglucose), MRI (magnetic resonance imaging), SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis), FD (fibrous dysplasia)
