Early and post-treatment imaging findings in perineural spread: a pathway to diffuse muscle metastasis in recurrent bladder carcinoma.
Journal of Nippon Medical School = Nippon Ika Daigaku zasshi(2023)
摘要
Perineural spread (PNS) from pelvic carcinoma has been regarded as a pathway to muscle and bone metastasis. However, few cases have been reported, especially in patients with bladder carcinoma. In the present report, we discuss a case of diffuse cancer involvement in the muscle 5 years after radical cystectomy for advanced bladder carcinoma. Careful observation of temporal changes on medical images confirmed PNS as the pathway to muscle metastasis (i.e., primary PNS). Our report presents early and post-treatment CT, MRI and FDG-PET/CT findings of PNS from the bladder carcinoma.
