胰 腺 的 超 声诊断  东院超声科 ;胰腺囊肿Cysts;真性囊肿Cysts;真性囊肿Cysts;真性囊肿Cysts;;假性囊肿Cysts;假性囊肿Cysts;;胰腺炎后体尾部囊肿;;外伤后胰尾部囊肿;;多囊胰;多囊胰腺声像图表现：胰腺内见多个大小不等囊性结构（小箭头所示），该患者同时并有多囊肾。 LIVER—肝脏；PAN—胰腺；AO—腹主动脉;;;胰腺癌Pancreatic Carcinoma ;二、胰腺癌;胰腺癌Pancreatic Carcinoma ;胰腺癌Pancreatic Carcinoma ;胰腺癌Pancreatic Carcinoma;胰腺癌Pancreatic Carcinoma;胰头癌压迫胆总管引起胆总管扩张。 CBD—胆总管；MASS—肿块；PV—门静脉;胰头癌压迫胰管引起胰管扩张。 实心箭头示胰管；空心示胰头部肿块;Tumour in the head of the pancreas (arrows), confirmed by CT. ;The tumour in (B) displays considerable vascularity on colour Doppler. (Note the colour sensitivity setting has been reduced to accommodate this, so eliminating low-velocity flow from the splenic vein.);胰头占位伴主胰管扩张、肝转移metastases ;;;;;胰头占位及周围淋巴结肿大肝内实占，门脉内瘤栓;;胰头后方肿大LN;肝左叶内实性占位;门脉主干内瘤栓;胰体部肿块声像图。 Liver—肝脏；SV—胰后脾静脉；SA—脾动脉；P—胰腺；SMA—肠系膜上动脉 ;胰尾部肿块声像图。 P—胰腺；SV—胰后脾静脉；M—肿块 ;A complex mass (m) between the spleen (S) and the left kidney is a large carcinoma of the tail of the pancreas. ;胰腺体尾部占位伴肝内转移metastases ;;;;;;诊断与鉴别诊断;↑Metastatic deposit from primary breastcarcinoma in the body of the pancreas (arrow).→The uncinate process is relativelyhypoechoic (arrows) because of fatty sparing.;Focal acute pancreatitis in the head of the pancreas. The CBD is obstructed by a hypoechoic mass inthe head, with blood clots and debris within the duct. The differential diagnosis was malignancy.
