【摘要】：目的觀察全身少見部位神經(jīng)內(nèi)分泌癌的CT與MRI表現(xiàn),提高對其認識。方法回顧性分析經(jīng)病理證實的18例神經(jīng)內(nèi)分泌癌患者的臨床及CT與MRI資料。8例行CT檢查,其中4例行CT增強掃描;17例行MRI檢查,其中13例行動態(tài)增強掃描。結(jié)果位于鼻腔鼻竇7例,子宮6例,卵巢1例,乳腺3例,腎臟1例。11例邊界清晰,7例邊界欠清。CT表現(xiàn):軟組織密度影,病變周圍明顯骨質(zhì)破壞及轉(zhuǎn)移灶,增強掃描病灶呈中等程度強化。MRI表現(xiàn):7例呈長T_1、長T_2信號,3例呈等T_1、稍長T_2,3例呈稍長T_1、混雜長T_2信號,1例呈等T_1、等T_2信號,3例子宮頸內(nèi)膜不均勻增厚未見明顯異常信號。4例DWI高b值彌散受限呈稍高信號,11例彌散受限呈高信號,2例未見明顯受限,平均ADC值為(0.64±0.12)×10~(-3)mm~2/s。增強掃描可見病變呈中等程度強化。時間-信號強度曲線:流入型2例,平臺型3例,流出型8例。結(jié)論少見部位神經(jīng)內(nèi)分泌癌CT與MRI具有一定特征性改變,CT結(jié)合MRI檢查可明確病變的范圍及有無轉(zhuǎn)移,通過MRI動態(tài)增強可以了解病變的血供情況,有利于明確診斷并協(xié)助臨床醫(yī)師制定治療方案。
[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弿鐥呯伓鍛堜腑絳夌▼搴﹀己鍖，
