Abstract:
Objective To explore the manifestation of pancreatic metastases (PM)using contrast‐enhanced ultrasound (CEUS). Methods Eleven patients with PM confirmed by pathology or CT/MRI combined with clinical data were analyzed retrospectively. The manifestation on conventional ultrasound and the enhancement appearance on CEUS were analyzed. Results The primary malignant tumors included lung cancer(n=6), breast cancer(n=1), renal clear cell carcinoma(n=1), gastric cancer(n=1), rectal cancer(n=1)and leiomyosarcoma of uterus(n=1). Eight patients had one lesion and three were multiple. The maximum lesion diameter was 2. 0-5. 0cm. Eight of the 11 patients showed hypoechoic on conventional US. Three patients were diagnosed as probably PM, one probably malignant and 7 undetermined by US. In the early stage of CEUS, two patients showed hyper‐enhancement, six showed iso‐enhancement and 3 showed hypo‐enhancement I.n the late stage of CEUS, nine patients (9/11) showed hypo‐enhancement. Seven patients showed homogeneous enhancement S.ix patients were diagnosed as PM, three malignant, one neuroendocrine tumor and one undetermined by CEUS. Conclusions PM showed certain characteristics on CEUS. The hyper‐or iso‐enhancement at the early stage of CEUS and history of primary cancer is helpful for diagnosis of PM.
