Asymptomatic Liver Abscesses Mimicking Metastases in Patients after Whipple Surgery: Infectious Complications following Percutaneous Biopsy—A Report of Two Cases

Figure 1

(a) Patient with history of cholangiocarcinoma status after pancreaticoduodenectomy. Axial contrast-enhanced CT image obtained a few weeks after surgery demonstrates one of the two new hepatic lesions in segment 8 (arrow). (b) Axial image from CT guided needle biopsy of the same lesion. The biopsy needle is placed within the lesion to obtain one of core samples. (c) Axial contrast-enhanced CT image one day after biopsy demonstrates new right perihepatic/subdiaphragmatic collection (asterix), which cultured positive for E. coli. The biopsied lesion is visible (arrow). (d) Histologic examination of core specimens shows a granuloma along with a mixed inflammatory infiltrate composed of lymphocyte, eosinophils, and neutrophils. (e) Contrast-enhanced CT image three months after biopsy shows resolution of liver lesions. The area of the biopsied segment 8 lesion is marked by an arrow.
