3.Which of the following features would suggest a benign nature to a finding in this anatomic location?
该部位的病变如果出现哪些征象,可以提示为良性病变?
Thick walls, fluid-filled 厚壁、内含液体
Solid components, enhancing 实性成分、增强扫描强化
Thin walls, fluid-filled 薄壁、内含液体
4.Typical management of this finding includes needle biopsy.
该病一般需要进行穿刺活检定性。
True
False
答案:
- AsymptomaticThe most common presentation of this finding is asymptomatic, and it is usually discovered incidentally. Rarely does it present as chest pain. The most severe presentation is cardiac tamponade. It almost never presents as reflux.
该病的患者通常无明显临床症状,为偶然发现。胸痛很少出现。重症患者可能出现心包压塞。而胃食管返流症状几乎不会出现。
- FalseThere is a cystic anterior mediastinal mass without substantial mass effect upon adjacent structures, but further characterization with gadolinium-enhanced MRI is necessary, especially with such a large cyst, to definitively rule out malignancy.
该病灶为上纵膈囊性肿块,无明显实性部分,对邻近器官无侵犯。但仍需进行MRI增强扫描,以排除恶性可能,特别是较大的囊性病灶。
- Thin walls, fluid-filled
- FalseFurther characterization with MR imaging is performed. Current imaging suggest a benign etiology, and biopsy is not recommended.
现有的影像学检查提示病灶为良性,MRI进一步检查可以提供更多的特征性表现,而无需进行穿刺活检。
