Pulmonary artery aneurysm presenting as a peripheral coin lesion--the danger of needle biopsy
Cardiovascular and Interventional Radiology
|January 1, 1984
Abstract:
A peripheral pulmonary artery aneurysm appeared as a solitary, smooth and discrete coin lesion in the lung. The aneurysm was surgically resected. Various etiologies possibly responsible for this entity are discussed. The complications of transthoracic needle aspiration biopsy are reviewed, with emphasis on the hazards of puncturing a vascular lesion, as well as suggested steps to avoid this complication.
Insights
A peripheral pulmonary artery aneurysm presented as a lung coin lesion and was surgically removed. Review covers potential causes and risks of needle biopsy, emphasizing vascular lesion puncture hazards.
Area of Science:
- Cardiovascular Medicine
- Pulmonary Medicine
- Radiology
Background:
- Peripheral pulmonary artery aneurysms are rare vascular anomalies.
- They can mimic benign lung nodules on imaging.
- Understanding their etiology and management is crucial.
Observation:
- A case of a solitary, smooth, discrete coin lesion in the lung was identified.
- This lesion was diagnosed as a peripheral pulmonary artery aneurysm.
- The aneurysm was successfully treated with surgical resection.
Findings:
- The study discusses various potential etiologies for peripheral pulmonary artery aneurysms.
- It reviews complications associated with transthoracic needle aspiration biopsy.
- Specific emphasis is placed on the risks of puncturing vascular lesions.
Implications:
- Accurate diagnosis of pulmonary artery aneurysms is essential to avoid misdiagnosis as malignancy.
- Awareness of vascular lesion risks can guide safer biopsy techniques.
- Surgical resection remains a viable treatment option for symptomatic or large aneurysms.
