A 31 year old female with a 3 month history of focal right mid posterior thoracic pain, and solitary lytic lesion in the right 7th rib posteriorly on bone scan (SPECT/CT) was referred for PET/CT to identify alternate site for biopsy in suspected malignancy. The patient had no significant past medical history and was afebrile with mildly elevated inflammatory markers. A solitary intensely FDG avid focus was demonstrated localised to a well-defined lytic lesion with partial cortical erosion on the posterior aspect of the right 7th rib. No adjacent soft tissue abnormality was seen. No other site of biopsy was demonstrated. As malignancy (metastatic or primary) was not excluded, CT guided localisation with hookwire and blue dye injection was performed immediately prior to partial resection of the right 7th rib. Histopathology confirmed the diagnosis of eosinophilic granuloma.
None declared.
一名31岁女性，有3个月的右侧中后胸壁局限性疼痛病史，骨扫描（SPECT/CT）显示右侧第7后肋有孤立性溶骨性病变，因怀疑为恶性肿瘤，转诊行PET/CT以确定活检的替代部位。患者既往无重大病史，无发热，炎症指标轻度升高。PET/CT显示右侧第7后肋后侧有一个孤立的、FDG摄取强烈的病灶，位于一个边界清晰的溶骨性病变内，伴有部分皮质侵蚀。未见相邻软组织异常。未发现其他活检部位。由于未排除恶性肿瘤（转移瘤或原发性肿瘤），在右侧第7后肋部分切除术前立即进行了CT引导下的定位，并用钩丝和蓝色染料注射。组织病理学确诊为嗜酸性肉芽肿。
