髌前皮下囊滑囊炎的MRI表现

MRI Findings of the Subcutaneous Prepatellar Bursitis

摘要: 目的:探讨髌前皮下囊(SPB)滑囊炎的MRI表现特征和鉴别诊断。方法:回顾性分析临床随访证实的28例髌前皮下囊滑囊炎的0.35 T MRI资料。结果:27例患者有急慢性膝前损伤史,1例有强直性脊柱炎病史。以膝前疼痛肿胀为主要临床表现。MRI表现为髌前皮下紧贴髌骨的扁圆形影,T1WI为中低、T2WI为中高信号。大小:2.8 cm×0.5 cm×1.9 cm^14.8 cm×3.6 cm×9.3 cm,平均6.6 cm×2.0 cm×3.7 cm。MRI显示以轴位为佳。结论:认识髌前皮下囊滑囊炎的临床及MRI表现特征有助于早期正确诊断该病。

Abstract: Objective: To investigate the MR/findings and differential diagnosis of the subcutaneous prepatellar bursitis (SPB). Methods: A retrospective analysis of 0.35T MR/data of 28 cases with the SPB confirmed clinically Results: 27 patients had a history of acute or chronic knee injury, 1 patients with ankylosing spondylitis. All were with painless swelling of anterior knee. MR/was characterized by a oblateness with medium or low signal in T1WI and medium or high signal in T2WI clingy to the patella. Size: 2.8cm×0.5cm×1.9cm~14.8cm×3.6cm×9.3cm with an average of 6.6cm×2.0cm×3.7cm. Axis MR/showed better. Conclusion: It is helpful for early diagnosis of SPB to understand the features of the clinical and MR/manifestations.
