摘要
我们报告一位已知甲状腺恶性肿瘤(低分化甲状腺癌，PDTC)的患者，在接受全身18氟脱氧葡萄糖正电子发射断层扫描(18F FDG PET CT)时，意外发现了一种未怀疑的色素绒毛结节性滑膜炎(PVNS)。FDG PET显示左肩胛骨喙突附近肩胛下肌FDG增强病灶。随后的MRI显示左侧盂前关节病变靠近囊下肌腱提示PNVS起源于囊下滑囊。本病例强调了FDG PETCT在肌肉骨骼疾病(如PVNS)中的非肿瘤学应用。
Incidental Detection of Pigmented Villonodular Synovitis by 18FDG PETCT Imaging in a Case of Poorly Differentiated Thyroid Carcinoma
We report the incidental identification of an unsuspected Pigmented Villonodular Synovitis (PVNS) in a patient of known thyroid malignancy (poorly differentiated thyroid carcinoma, PDTC) who underwent whole body 18 Fluorine Flurodeoxyglucose Positron Emission Tomography Computed Tomography (18F FDG PET CT). FDG PET CT showed a FDG avid enhancing lesion in the subscapularis muscle near coracoid process of left scapula. A subsequent MRI showed a lesion anterior to the left glenoid in close proximity to the subcapsularis tendon suggestive of PNVS arising from the subcapsular bursa. This case highlights the non oncological utility of FDG PETCT in musculoskeletal disorders like PVNS.
