Ultrasonography will reliably detect popliteal cysts of clinically significant size and improvements in ultrasound imaging have enhanced the value of ultrasound in relation to arthrography in the assessment of cyst rupture. Forty-eight knees in 25 patients suspected of having a popliteal cyst were examined by ultrasonography followed immediately by arthrography. Popliteal cysts were demonstrated in 40% (19/48) by ultrasound and in 46% (22/48) by arthrogram. Arthrography detected small cysts not seen with ultrasound, but altrasonic scanning showed cysts which did not fill on arthrography. A ruptured cyst or deep venous thrombosis was suspected in 10 patients. Rupture was confirmed in two patients by arthrography, in both of whom soft tissue changes and attenuation of the distal margin of the cysts were shown by ultrasound.
超声检查能够可靠地检测出具有临床意义大小的腘窝囊肿，并且超声成像技术的改进提高了超声在评估囊肿破裂方面相对于关节造影的价值。对25例疑似患有腘窝囊肿的患者的48个膝关节进行了超声检查，随后立即进行关节造影。超声检查显示40%（19/48）的患者存在腘窝囊肿，关节造影显示46%（22/48）的患者存在腘窝囊肿。关节造影检测出了超声未发现的小囊肿，但超声扫描显示出关节造影时未显影的囊肿。10例患者疑似囊肿破裂或深静脉血栓形成。关节造影证实2例患者囊肿破裂，超声均显示这2例患者存在软组织改变及囊肿远端边缘变钝。
