Uncommon diseases of the popliteal artery include cystic adventitial disease, popliteal artery entrapment syndrome (PAES) and popliteal artery aneurysm (PAA). Because all of these conditions may present with pain or intermittent claudication, imaging is crucial for differentiating them and directing management. Delayed diagnosis can lead to major complications, including acute limb ischemia. Ou...

Background: Several vascular complications are known to occur in association with the acquired immunodeficiency syndrome (AIDS) and recent publications have called attention to the development of pseudoaneurysms of large arteries in patients with AIDS. Case report: We report on 2 patients with AIDS aged 23 and 31 years with pseudoaneurysms of the abdominal aorta and common iliac arteries. After...

Although regional anaesthesia is a commonly preferred anaesthesia technique for pregnant patients undergoing non-obstetric surgery, peripheral nerve blocks are relatively less administered. The use of popliteal sciatic nerve block for foot-ankle surgery has been presented for a nulliparous parturient at 32 weeks of gestation scheduled to undergo surgical exploration of an arterial pseudoaneurys...

Injury of popliteal artery during total knee arthroplasty is a relatively rare complication. We report on one case of transverse semi-dissection of the popliteal artery during the tibial cut and one case of popliteal pseudoaneurysm formation caused by Hohmann retractors. Diagnosis was made early in the first case but it was delayed in the second due to misdiagnosis of deep vein thrombosis. Both...

Popliteal cysts occur commonly in both normal and arthritic knees. Most cysts are formed by distension of the medially situated semimembranosus bursa. Popliteus bursa distension occurs uncommonly as a lateral popliteal cyst. Two cases of rupture of lateral cysts which produced symptoms related to the anterolateral lower leg are reported. The difficulty of diagnosing the condition because of thi...

Popliteal cyst commonly presents as an ellipsoid mass with uniform low signal intensity on T1-weighted magnetic resonance images and high signal intensity on T2-weighted images. Here, we describe a popliteal cyst with unusual appearance on magnetic resonance imaging, including heterogeneous intermediate signal intensity on T2-weighted images. Arthroscopic cyst decompression revealed that the cy...

Popliteal or otherwise called Baker’s cyst represents a fluid distension of the gastrocnemiosemimembranosus bursa and is usually incidentally found on imaging studies. However, the clinical manifestation of symptomatic Baker’s cyst is similar to thrombophlebitis hence the term pseudothrombophlebitis syndrome. We add to the literature a case of a partially ruptured popliteal cyst in which locall...

Although rare, aneurysms of the infrapopliteal arteries are commonly associated with trauma. However, the combination of bilateral popliteal aneurysm with true bilateral aneurysms of the posterior tibial arteries has not been previously described. Here, as well as reviewing the relevant literature, we report the clinical and radiological aspects, and the surgical management of a 60-year-old man...

Figure 1. The tumor in the right popliteal fossa (naked eye appearance and MRI). DESCRIPTION A 36-year-old woman presented with a cystic lesion located on the right popliteal fossa, which grew slowly for 7 years and became remarkably larger in the last few months. The lesion was dark red in color (Fig 1) and elastic hard in consistency. When punctured by her primary care physician, darkish bloo...
