Insights
A rare case of adventitial cystic disease causing intermittent claudication in a 50-year-old man resolved spontaneously. Imaging confirmed the popliteal adventitial cyst decreased in size without recurrence.
Area of Science:
- Vascular Surgery
- Radiology
- Medical Case Reports
Background:
- Adventitial cystic disease is a rare condition causing arterial stenosis.
- Popliteal artery involvement can lead to critical limb ischemia and intermittent claudication.
Observation:
- A 50-year-old male presented with intermittent claudication due to right popliteal artery stenosis.
- Imaging (DSA and CT) suggested compression by a tumor-like lesion, consistent with adventitial cystic disease.
Findings:
- The patient experienced symptom resolution within three weeks.
- Follow-up imaging demonstrated spontaneous decrease in the size of the popliteal adventitial cyst.
- No recurrence of the adventitial cystic disease was observed.
Implications:
- This case highlights the potential for spontaneous regression of adventitial cystic disease.
- Conservative management and observation may be considered in select cases of popliteal adventitial cysts.
- Further research into the natural history and management of this rare condition is warranted.
Abstract:
The case was 50-year-old man. He was admitted to our hospital suffering from intermittent claudication. DSA and CT showed stenosis of the right popliteal artery due to compression by the tumor like lesion. The adventitial cystic disease was suggested. Three weeks later he had no symptom. DSA and CT revealed no reappearance of the adventitial cystic disease. The popliteal adventitial cyst spontaneously decreased in size. It is a very rare case.
