概括

硬化血管形结节转变 (SANT) 是一种罕见的脏瘤. 虽然通常是良性的,但它的成像可以模仿转移,往往需要脊髓切除术进行诊断.

科学领域:

病理学病理学病理学
放射学放射学是一门学科.
在瘤学瘤学.

背景情况:

硬化性血管瘤结节转变 (SANT) 是一种罕见的脏血管瘤,于2004年首次被描述.
病因和精确的血管血统仍然是未知的.
大多数病例是无症状的;然而,可能会出现贫血或腹痛等症状.

研究的目的:

提出两个被诊断为SANT的病例.
审查SANT的临床,放射学和组织病理学特征.
讨论这种罕见的脏病变的诊断和管理挑战.

主要方法:

对两例SANT病例的临床数据,放射学发现 (动态MRI,PET-CT) 和组织病理特征的审查.
关于SANT特征,诊断和管理的文献综述.

主要成果:

SANT呈现了特征性的但不是病理学性的放射性发现,包括MRI上带有中心点填充的辐射图案.
它可能在PET-CT上显示超高代谢,可能模仿转移性疾病.
尽管脏切除术是良性的,但由于其与恶性瘤的成像相似性,脏切除术通常用于确定的诊断.

结论:

SANT是一种罕见的脏瘤,越来越多地被识别,特别是在瘤患者中.
确切的诊断往往需要手术干预 (脊髓切除术),因为它的放射性外观.
SANT在诊断后表现出良性行为,不需要进一步的治疗或监测.

Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
