We describe the case of a patient with known history of psoriasis that presented with 1 year of unexplained fever, muscle weakness and marked weight loss, suspicious for B symptoms of a malignant origin. [(18)F]-Fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT) scans demonstrated an unusual serpiginous pattern of uptake in the fascia and muscles as well as lymph node activity. Multiple histological samples, including a final PET-probe guided lymph node surgical resection, excluded malignancy and confirmed the diagnosis of reactive inflammatory changes, with a plausible diagnosis of autoimmune lymphoproliferative syndrome with associated lymphadenitis, fasciitis and myositis, possibly mediated by tumor necrosis factor (TNF) inhibitor. To our knowledge, there is no evidence of a previously reported FDG uptake pattern of fascia and muscle involvement in psoriatic arthritis.
我们报告了一例有银屑病病史的患者,该患者出现了长达1年的不明原因发热、肌肉无力和显著体重减轻,怀疑为恶性肿瘤起源的B症状。[18F]氟脱氧葡萄糖正电子发射断层扫描-计算机断层扫描(FDG-PET/CT)显示,筋膜和肌肉中存在异常的匐行性摄取模式以及淋巴结活性。多个组织学样本,包括最终的PET引导下淋巴结手术切除样本,排除了恶性肿瘤,并确诊为反应性炎症改变,合理的诊断为自身免疫性淋巴增生综合征伴相关淋巴结炎、筋膜炎和肌炎,可能由肿瘤坏死因子(TNF)抑制剂介导。据我们所知,尚无证据表明先前报道过银屑病关节炎中筋膜和肌肉受累的FDG摄取模式。
