| Summary: | Abstract Background Cystic adventitial disease (CAD) is a rare vascular condition that causes arterial stenosis due to the presence of a cyst in the adventitia (outer layer) of the artery. It is most commonly seen in young and middle-aged men, with an occurrence rate of around 0.1% among vascular diseases. Symptoms may include intermittent claudication, rest pain, and, in severe cases, ulcers or limb ischemia. CAD is often underdiagnosed due to its rarity and the broad range of differential diagnoses for arterial obstruction. Case presentation This case describes a 36-year-old female who presented with sudden left lower limb soreness that worsened with activity over five days, but without symptoms such as intermittent claudication or rest pain, which are typically associated with other vascular diseases. The patient had no significant history of smoking or other risk factors for peripheral arterial disease. Imaging studies, including angiography, revealed a focal filling defect and luminal narrowing in the popliteal artery (PA), which suggested the presence of an abnormality in the vessel wall. Given the findings and the patient’s symptoms, surgical intervention was planned. The procedure involved the resection of the affected portion of the artery and replacement with an autologous vein graft. Pathological examination of the resected arterial segment confirmed the diagnosis of CAD, revealing a cyst in the adventitia filled with a gelatinous substance. Conclusion CAD is a rare but important cause of arterial obstruction and the etiology of CAD is still unclear. It should be considered in younger patients with symptoms of limb ischemia, especially without smoking history or traditional risk factors. Imaging techniques, such as ultrasound and CT/MRI angiography, are crucial for diagnosis. Surgical management, typically involving resection and autologous grafting, is often required to alleviate symptoms and prevent further vascular complications. However, it is worth mentioning that conservative treatments, such as avoiding triggering movements, are sometimes sufficient. Since CAD is rarely suspected, awareness of this condition can help in making an early diagnosis, potentially avoiding misdiagnosis and improving patient outcomes. |
