Spontaneous regression of cystic adventitial disease (CAD) of the popliteal artery is rare. In this report, we describe a 53-year-old woman who presented with left calf pain and was diagnosed with CAD with popliteal artery stenosis, which regressed without therapy. The disease was diagnosed via computed tomography, and a surgical intervention was planned at the time of diagnosis. However, her symptoms disappeared 2 months after the initial presentation. Ultrasonography and computed tomography revealed spontaneous regression of the cystic lesions and resolution of the popliteal artery stenosis. During the 29-month follow-up period, her symptoms did not recur. Although CAD often requires surgical intervention, it may be acceptable to carefully observe patients with spontaneous regression for some time to check for recurrence.
Case Details
Disease Location
Knee
Personal Characteristics
53-year-old woman
Clinical Characteristics
Presented with pain and numbness in the left calf after running a half marathon. Contrast-enhanced computed tomography (CT) performed 1 month after the development of symptoms revealed compression of the left popliteal artery by cystic lesions with severe luminal stenosis, which led to the diagnosis of cystic adventitial disease (cad). The pulses of the left dorsal pedal and posterior tibial arteries were palpable on physical examination.
Remission Characteristics
8 days later, ultrasonography demonstrated shrinkage of the cystic mass and partial improvement in the popliteal artery stenosis. Three weeks later, a repeat ultrasonography demonstrated further regression of the cystic lesions and the affected artery was not stenosed. Four months after the initial CT, a repeat CT scan revealed shrunken cystic lesions adjacent to the popliteal artery which seemed to communicate with the capsule of the knee joint,
Treatment & Mechanisms
Proposed Remission Mechanisms
The cyst content might have drained through this connection, leading to the shrinkage of the lesion
Non-Clinical Treatment
None reported
