【摘要】：目的观察全身少见部位神经内分泌癌的CT与MRI表现,提高对其认识。方法回顾性分析经病理证实的18例神经内分泌癌患者的临床及CT与MRI资料。8例行CT检查,其中4例行CT增强扫描;17例行MRI检查,其中13例行动态增强扫描。结果位于鼻腔鼻窦7例,子宫6例,卵巢1例,乳腺3例,肾脏1例。11例边界清晰,7例边界欠清。CT表现:软组织密度影,病变周围明显骨质破坏及转移灶,增强扫描病灶呈中等程度强化。MRI表现:7例呈长T_1、长T_2信号,3例呈等T_1、稍长T_2,3例呈稍长T_1、混杂长T_2信号,1例呈等T_1、等T_2信号,3例子宫颈内膜不均匀增厚未见明显异常信号。4例DWI高b值弥散受限呈稍高信号,11例弥散受限呈高信号,2例未见明显受限,平均ADC值为(0.64±0.12)×10~(-3)mm~2/s。增强扫描可见病变呈中等程度强化。时间-信号强度曲线:流入型2例,平台型3例,流出型8例。结论少见部位神经内分泌癌CT与MRI具有一定特征性改变,CT结合MRI检查可明确病变的范围及有无转移,通过MRI动态增强可以了解病变的血供情况,有利于明确诊断并协助临床医师制定治疗方案。
[Abstract]:Objective to observe CT and MRI findings of neuroendocrine carcinoma in rare part of the body.Methods the clinical features and CT and MRI findings of 18 patients with neuroendocrine carcinoma confirmed by pathology were retrospectively analyzed. Ct enhanced CT scan was performed in 17 patients and dynamic enhanced CT scan was performed in 13 patients.Results there were 7 cases located in nasal cavity and sinuses, 6 cases in uterus, 1 case in ovary, 3 cases in mammary gland, 1 case in kidney, 1 case in clear boundary and 7 cases with unclear boundary. Ct findings showed soft tissue density, obvious bone destruction and metastasis around the lesion.澧炲己鎵�鎻忕梾鐏跺憟涓�绛夌▼搴﹀己鍖，
