Abstract:
Objective To assess the value of ultrasonography(US)in the diagnosis of pancreas endocrine tumors(PET).Methods Thirty-six patients with PET confirmed by surgery and pathology were retrospectively reviewed.Results There were 37 PET in 36 patients,among which 33 tumors in 32 cases were detected bv US,four tumors were missed on US and the detection rate was 88.9%(32/36).The tumor size was 1.0 cm×0.8 cm～12.9 cm× 11.3 cm.Among 12 cases of equal to or less than 2 cm,9 tumors were detected and the detection rate was 75.0%.PET presented mostly hypoechogenicity(78.8%),other 7 cases presented mixed-echogenicity.Color Doppler US was performed on 12 cases and 11 tumors showed color blood signals.Abundant flow signal was detected in 8 tumors(66.7%).PET were found in pancreatic head (n=11),neck(n=2),body(n=6)and tail(n=11),which was diagnosed correctly in 30 cases (81.1%).Conclusions US is a useful tool in the detection and diagnosis of PET.
