Abstract

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.

神经周围扩散的早期和治疗后影像学发现：复发性膀胱癌弥漫性肌肉转移的途径。

盆腔癌的神经周围扩散（PNS）一直被认为是肌肉和骨骼转移的途径。然而，相关报道很少，尤其是膀胱癌患者。在本报告中，我们讨论了一例晚期膀胱癌根治性膀胱切除术后 5 年肌肉弥漫性癌症受累的病例。通过仔细观察医学影像上的时间变化，证实 PNS 是肌肉转移的途径（即原发性 PNS）。我们的报告介绍了膀胱癌 PNS 早期和治疗后的 CT、MRI 和 FDG-PET/CT 结果。

期刊介绍： The international effort to understand, treat and control disease involve clinicians and researchers from many medical and biological science disciplines. The Journal of Nippon Medical School (JNMS) is the official journal of the Medical Association of Nippon Medical School and is dedicated to furthering international exchange of medical science experience and opinion. It provides an international forum for researchers in the fields of bascic and clinical medicine to introduce, discuss and exchange thier novel achievements in biomedical science and a platform for the worldwide dissemination and steering of biomedical knowledge for the benefit of human health and welfare. Properly reasoned discussions disciplined by appropriate references to existing bodies of knowledge or aimed at motivating the creation of such knowledge is the aim of the journal.
