DX

Carcinoma

Sonographic Differential Diagnosis

Abdominal neoplasia involving pancreas and likely metastatic disease to the liver with nodular omental changes. Carcinomatosis or similar neoplasia suspected.

Image Interpretation

Pancreas was hypoechoic, nodular, and irregular. This is likely the site of primary neoplasia. A moderate amount of ascites was noted. There were nodular omental changes. The liver presented multiple mixed echogenic masses occupying most of the parenchyma; these were non-resectable in the deep left, right and caudal aspects of the liver. There was a swollen irregular contour and pericapsular inflammatory pattern. The gallbladder was unremarkable.

Outcome

None

Clinical Differential Diagnosis

Ascites: transudate, cardiac disease, neoplasia, septic peritonitis, non-septic peritonitis (bile, urine, FIP), hemorrhage; Chronic kidney disease.

Sampling

Ultrasound-guided fine needle aspirate of the intestine was consistent with a carcinoma. The FNA also contained a rare bacteria which was most likely a contaminant.
