Summary
Pulmonary arteriovenous malformations (AVMs) are abnormal blood vessel connections in the lungs. This case study highlights their diagnosis using radionuclide angiography after an unusual finding on a lung scan.
Area of Science:
- Vascular Medicine
- Diagnostic Imaging
Background:
- Pulmonary arteriovenous malformations (AVMs) represent abnormal vascular connections between pulmonary arteries and veins.
- These congenital conditions allow unoxygenated blood to bypass the lungs, potentially leading to serious complications.
- Common symptoms include hemoptysis, dyspnea, and chest pain, with a higher prevalence in women.
