Intracystic papillary neoplasm of the gallbladder is a rare preinvasive neoplastic lesion with similar characteristics as intraductal papillary mucinous neoplasm and other papillary neoplasms of pancreaticobiliary system. We report a case of 48-year-old woman with a history of recurrent right flank chondrosarcoma and gallbladder lesion on MRI and PET/CT interpreted as indeterminate for metastatic disease. Subsequent cholecystectomy showed intracystic papillary neoplasm. With gallbladder lesions being rare on PET/CT, this case illustrates the importance of considering both primary and secondary tumors in the differential diagnosis.
胆囊腔内乳头状肿瘤是一种罕见的癌前病变，其特征与胆管内乳头状黏液性肿瘤和其他胰胆管系统的乳头状肿瘤相似。我们报告了一例 48 岁女性病例，该患者有复发性右肋软骨肉瘤病史，MRI 和 PET/CT 显示胆囊病变，为转移性疾病的不确定表现。随后的胆囊切除术显示为胆囊腔内乳头状肿瘤。由于胆囊病变在 PET/CT 上较为罕见，因此该病例说明了在鉴别诊断中既要考虑原发性肿瘤也要考虑继发性肿瘤的重要性。
