Adventitial cystic disease is a rare nonatheromatous cause of popliteal artery disease. Here, we present a case of a 51-year-old male patient who presented with right calf claudication caused by adventitial cystic disease. Preoperative magnetic resonance imaging and intraoperative findings revealed the presence of a connection between the cyst and adjacent knee joint. In addition, histopathological examination revealed that the tissue structure of the connection was similar to that of adventitial cysts. The tissue composed of 2 types of cells, namely macrophages and fibroblast-like cells, and lesional cells expressed D2-40. These findings supported the ganglion theory as the underlying physiopathology of this disease and were helpful in deciding the management of this case.

The present study aimed to evaluate the histologic, histochemical, and immunohistochemical changes in buffalo livers with cystic echinococcosis. Noninfected and infected livers were collected from the freshly slaughtered buffalo at the Aligarh abattoir. Small pieces of both infected and noninfected livers ( = 5) were cut and processed for histologic and histochemical studies.

Common femoral vein aneurysms are rare and they are often misdiagnosed as soft tissue masses or as hernias. In this case report, we review literature and describe a patient who presented with left inguinal mass associated with ipsilateral limb swelling. He was initially misdiagnosed as cystic adventitial disease of common femoral vein.

Adventitial cystic disease (ACD), a rare vascular disease characterized by mucus accumulation in the adventitia of blood vessels, typically affects the popliteal artery. We present the case of a 61-year-old female diagnosed with ACD in 2018 who was initially treated with endovascular stenting and percutaneous aspiration of the cyst. The patient, who had been asymptomatic for 5 years, developed a stent fracture and pseudoaneurysm requiring surgical intervention.

Article Synopsis
  • A 67-year-old woman experienced leg pain due to severe popliteal artery stenosis caused by a popliteal ganglion cyst.
  • After opting out of vein bypass surgery, the patient was successfully treated with ultrasound-guided aspiration of the cyst, restoring normal blood flow.
  • This case is notable as it is the first reported instance where ganglion cyst aspiration successfully relieved claudication caused by a compressed popliteal artery, highlighting a new treatment option for cystic adventitial disease.
