Title: MRI, enhanced CT, and FDG PET/CT in primary retroperitoneal mucinous cystadenocarcinoma. Author: Dong A, Zhai Z, Wang Y, Zuo C. Journal: Clin Nucl Med; 2015 Jan; 40(1):50-3. PubMed ID: 24445275. Abstract: Primary retroperitoneal mucinous cystadenocarcinoma (PRMC) is an extremely rare neoplasm. We present a case of PRMC with MRI, enhanced CT, and FDG PET/CT findings. Abdominal MRI showed a cystic lesion in the retroperitoneum with a mural nodule. The mural nodule showed progressive enhancement on enhanced CT and intense FDG uptake on early PET/CT with increased SUVmax on delayed PET/CT. Laparoscopy was performed. Retroperitoneal mucinous cystadenocarcinoma was confirmed histopathologically. Metastasis from gastrointestinal tract or ovary was excluded. This case indicates, although rare, PRMC should be considered when a hypermetabolic retroperitoneal cystic lesion with bilateral normal ovaries is found on FDG PET/CT.[Abstract] [Full Text] [Related] [New Search]
