Summary
This case report details multifocal osteosarcoma with rare metastases to the kidney, lung, and lymph nodes. It highlights unusual radiological findings in skeletal, renal, pulmonary, and nodal imaging.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Osteosarcoma is a primary bone malignancy typically affecting children and young adults.
- Metastatic spread is common, but multifocal presentation with extraskeletal involvement is rare.
Observation:
- A rare case of multifocal osteosarcoma is presented.
- The patient exhibited widespread skeletal lesions.
- Metastatic disease involved the kidney, lungs, and lymph nodes.
Findings:
- Radiological imaging revealed multiple sclerotic bone lesions.
- A heterogeneous renal mass with calcifications was observed.
- Pulmonary metastases and enlarged, calcified lymph nodes (mediastinal and abdominal) were identified, complicated by pneumothorax.
Implications:
- This case underscores the importance of comprehensive radiological evaluation in suspected osteosarcoma.
- It expands the understanding of rare metastatic patterns in osteosarcoma.
- Highlights the diagnostic challenges posed by multifocal and extraskeletal involvement.
