MRI Findings of the Subcutaneous Prepatellar Bursitis

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.
