"T1: individual lesions are of variable signal dependent on mucoid content 4"
"T2/STIR: individual lesions are high signal 1,4"
"Digital subtraction angiography may demonstrate curvilinear/spiral narrowing of vessels with a paucity of collaterals and an absence of post-stenotic dilatation. When cystic lesions are large and eccentric they may displace the artery to one side, the so-called "scimitar sign" 4."
"Baker cyst - should demonstrate communication with the knee joint via the semimembranosus-gastrocnemius bursa"
"Cystic adventitial disease typically affects young to middle-aged individuals without evidence of atherosclerosis or other systemic vascular diseases 12. There is a recognised male predilection with an M:F ratio of ~15:1 9."
"Unilateral popliteal artery involvement is most common (~85%) with external iliac, common femoral, radial and ulnar arteries also being reported as being involved 12."
"Conservative management may be appropriate depending on symptom severity, and some cases resolve without intervention 13. Percutaneous cyst aspiration using ultrasound or CT is a minimally invasive treatment which can have durable results 14,15,18. Endovascular treatments including angioplasty and stenting have had mixed results 13,16. Surgical management is usually definitive but much more invasive; multiple techniques have been employed including exarterectomy and excision and bypass of the affected segment 13."
