Area of Science:

  • Oncology
  • Radiology
  • Pathology

Background:

  • Primary pulmonary osteosarcoma is an extremely rare malignancy.
  • Accurate diagnosis is crucial for patient management.

Observation:

  • Chest computed tomography (CT) identified calcified pulmonary masses.
  • Technetium-99m methylene diphosphonate (99mTc-MDP) bone scintigraphy revealed intense uptake in the masses.

Findings:

  • Radiographic findings suggested primary pulmonary osteosarcoma.
  • Needle biopsy and postmortem examination confirmed the histologic features of osteosarcoma.

Implications:

  • This case series emphasizes the utility of combined CT and bone scintigraphy in diagnosing primary pulmonary osteosarcoma.
