总结了１６例膝周局灶性血管瘤，术前诊断符合率６２．５％。临床表现以疼痛、肿物、压疼为主，尤以囊性可压缩性肿物及锐压疼最有特色。血管瘤可以导致关节功能障碍，引起活动疼、肌肉萎缩及伸屈受限。特殊检查以血管造影及同位素血池扫描最有意义，推荐同位素血池扫描为首选诊断、鉴别诊断及术后随访手段，灵敏度高，特异性强。病理蔓状血管瘤为主；注意浸润性脂肪血管瘤与一般血管瘤的鉴别。
Sixteen cases of focal hemangioma of the knee were summarized and the preoperative diagnosis coincidence rate was 62.5%. The main clinical manifestations are pain, mass and pressure pain, especially cystic compressible mass and sharp pressure pain. Hemangiomas can cause joint dysfunction, causing activity pain, muscle atrophy, and limited extension of flexion. Special angiography and isotope blood pool scanning are the most important for specific examinations. Recommended isotope blood pool scanning is the preferred method for diagnosis, differential diagnosis, and postoperative follow-up. It has high sensitivity and specificity. Pathological hemangioma is the main type; attention should be paid to the identification of invasive fatty hemangioma and general hemangiomas.
