Ganglion cysts (GCs) can arise from a variety of different areas, but those arising from Hoffa's fat pad in the knee are relatively rare. A number of different types of cysts are also found in the knee, including meniscus cysts, proximal tibiofibular cysts, and cruciate ligament ganglion cysts. In this case report, a 54-year-old female presented with left knee pain and swelling for eight weeks. In-office musculoskeletal ultrasound (US) was used to diagnose a Hoffa's fat pad ganglion cyst and aid in targeted steroid injection. The patient was followed up 21 weeks after the injection. She was pain-free, and US findings showed the cyst had significantly decreased in size. This case shows how musculoskeletal ultrasound, a relatively inexpensive diagnostic modality, can be used to accurately diagnose the cause of knee pain, guide an in-office procedure for the treatment of Hoffa's fat pad ganglion cyst, and aid in monitoring.
腱鞘囊肿（GCs）可起源于多种不同部位，但起源于膝关节 Hoffa 脂肪垫的腱鞘囊肿相对少见。膝关节中还可发现多种不同类型的囊肿，包括半月板囊肿、胫腓近端囊肿和交叉韧带腱鞘囊肿。在本病例报告中，一名 54 岁女性因左膝疼痛和肿胀 8 周前来就诊。采用门诊肌肉骨骼超声（US）诊断为 Hoffa 脂肪垫腱鞘囊肿，并辅助进行靶向类固醇注射。注射后 21 周对患者进行随访。她已无疼痛，超声检查结果显示囊肿大小显著减小。本病例展示了肌肉骨骼超声这种相对廉价的诊断方式如何能够用于准确诊断膝关节疼痛的病因、指导门诊治疗 Hoffa 脂肪垫腱鞘囊肿的操作并辅助进行监测。
