目的:研究发生于膝关节髌下脂肪垫区肿瘤或肿瘤样病变及其MRI表现。
方法:回顾性研究14例经手术病理证实的膝关节髌下脂肪垫区的肿瘤或肿瘤样病变的MRI表现。分析病变的MRI形态、平扫与增强的信号特点。
结果:14例15个病灶,滑膜腱鞘巨细胞瘤7例,肿块T1WI呈等信号或稍高信号,T2WI呈等信号5例,高信号肿块内有含铁血黄素低信号灶2例,轻度或不强化。髌下脂肪垫内海绵状血管瘤2例,T1WI呈等信号,T2WI呈显著高信号,明显强化。囊肿4例,T1WI低信号,T2WI呈高信号,无强化。滑膜纤维脂肪瘤2例,T1WI呈等或高信号,T2WI呈高信号。
结论:膝关节髌下脂肪垫区可发生多种肿瘤或肿瘤样病变,以滑膜腱鞘巨细胞瘤、海绵状血管瘤及滑膜囊肿多见。MRI表现具有一定的特征性,不失为术前定性诊断的有效方法。 |

| MRI diagnosis of tumors in the infrapatellar fat pad of knee joint:a report of 14 cases |

Abstract:
Objective:To study the tumor and tumor-like lesion in the infrapatepallar fat pad and it’s MR imaging findings.
Methods:A retrospective analysis of MR examination was performed in 14 patients (4 male, 10 female,ranging in age from 16 to 64 years,meanly 30.2 years) with pathologically-proved tumor or tumor-like lesion.The morphological manifestations and the features of signal and its intensively-enhanced ones of MRI were analyzed.
Results: Among 14 patients with 15 lesions,7 lesions were giant-cell tumor of tendon sheath(GCTTS),and T1WI signals of these tumors were showed with iso-intensity or slightly high intensity.In 5 of above 7 lesions of giant-cell tumor of tendon sheath,the iso-intensity T2WI signals were found.In other 2 of 7 lesions above it was found that the low intensive T2WI signals were observed in the tumor with high intensive signal due to hemosiderin deposition.These signals were slightly or not enhanced.Of all 15 lesions,2 were cavemous hemangioma in synovium with iso-intensity T1WI signals and obviously high intensive T2WI signals being significantly enhanced;4 lesion were synovial cyst with low signal intensity in T1WI MR imaging and high signal intensity in T2WI MR imaging with on enhancement;the rest 2 lesions were fibrolipoma with isointensive or high signal intensity in T1WI MR imaging and high signal intensity in T2WI MR imaging.
Conclusion: A number of tumors and tumor-like lesions may occure in the infrapatellar fat pad,in which giant-cell tumor of tendon sheath,cavemous hemangioma and synovial cyst are commonly observed.MR imaging with its special characteristics is an effective method for making correct diagnosis before operation. |
