Summary
Intrapulmonal round lesions on chest CT can mimic lung metastases. However, these lesions may represent anthracotic lymph nodes, even in patients with a history of malignancy.
Area of Science:
- Radiology
- Pulmonology
- Pathology
Background:
- Intrapulmonal round lesions present distinct radiologic features.
- Differential diagnosis includes metastases and benign conditions.
Observation:
- A 58-year-old man with a history of bladder and prostate carcinoma presented with multiple intrapulmonal round lesions on chest CT.
- These lesions mimicked metastatic disease.
Findings:
- Wedge-resected specimens revealed anthracotic lymph nodes.
- Intrapulmonal lymph nodes can mimic metastatic lesions.
Implications:
- Consider intrapulmonal lymph nodes in the differential diagnosis of round lung lesions.
- This finding is relevant even in patients with a history of malignancy.
