概括

小细胞前列腺癌 (SCPC) 很少会扩散到阴茎. 18F-FDG PET/CT成像有效检测到原发性SCPC及其罕见的阴茎转移,该患者此前被怀疑患有良性前列腺增生症.

科学领域:

在瘤学瘤学.
放射学放射学是一门学科.
泌尿器科泌尿器科泌尿器科泌尿器科

背景情况:

小细胞前列腺癌 (SCPC) 是前列腺癌的一种罕见而激进的变体.
诊断可能具有挑战性,经常模仿良性前列腺增生.
转移性SCPC的模式并未明确,罕见的extragenitourinary参与.

研究的目的:

报告一个罕见的小细胞前列腺癌与阴茎转移的病例.
为了说明先进的成像技术的诊断实用性,包括MRI和18F-FDG PET/CT,用于识别SCPC及其转移性传播.
强调在前列腺手术后持续性尿保留的情况下考虑SCPC的重要性.

主要方法:

一个77岁的男性患有持续性尿的病例介绍.
磁共振成像 (MRI) 包括T2WI,DWI,ADC和对比度增强的T1WI来描述前列腺和阴茎的质量.
18F-FDG PET/CT用于评估代谢活动和检测远程转移.
对活检样本进行组织病理学检查,以确定确诊.

主要成果:

核磁共振扫描显示前列腺和阴茎洞体中的软组织质量具有特征信号强度和增强模式,暗示恶性瘤.
18F-FDG PET/CT在前列腺原发性瘤,肝转移,特别是阴茎质量中显示FDG吸收增加.
活检证实了小细胞前列腺癌 (SCPC) 的诊断.

结论:

这一案例强调了18F-FDG PET/CT在检测初级SCPC及其转移性病变,包括罕见的阴茎干扰等方面的有效性.
先进的成像方法对于SCPC的准确分期和表征至关重要.
早期和准确的SCPC诊断对于适当的治疗计划和改善患者的治疗结果至关重要.

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
