To highlight the diagnostic value of multimodal imaging in identifying adventitial cystic disease (ACD) in a young patient presenting with exertional claudication.
Key Findings:
Duplex ultrasonography revealed significant stenosis of the distal left superficial femoral artery with a hypoechoic intramural lesion.
CTA showed segmental luminal narrowing and a hypodense lesion causing luminal compression.
MRI demonstrated characteristic features of ACD, including multiloculated cystic lesions and extrinsic compression of the arterial lumen.
Histopathology indicated a degenerative process with mucin-filled cysts and fibrous septa.
Interpretation:
Recognition of ACD's imaging features is crucial for differentiating it from atherosclerotic disease, especially in young patients without traditional cardiovascular risk factors.
Limitations:
The case study is based on a single patient, which may limit generalizability.
ACD is a rare condition, making it challenging to establish broader diagnostic criteria.
Conclusion:
This case highlights the importance of multimodal imaging in diagnosing ACD in young patients with exertional claudication.
