Abstract
A 58-year-old woman visited our hospital because of fever was detected to have an inflammatory response and elevated biliary enzyme levels on blood examinations. Subseguent abdominal ultrasound and CT scan revealed a 3×4 cm mass with enhancement effect in the center of the abdomen and a 3cm low-density region on the lateral segment of the liver. Small bowel endoscopy suggested the mass to be a suspicious GIST of the small intestine. Blood investigations and imaging findings indicated that the low density area might be a suspicious liver abscess, but a possibility of liver metastasis of GIST could not be ruled out.
Laparoscopy-assisted partial small bowel resection along with a needle biopsy of the liver was performed one month later. Results of pathological investigations confirmed the diagnosis of GIST in the small bowel region and an abscess in the lateral segment of the liver. Abdominal CT scan performed one month after the operation revealed that the liver abscess almost disappeared.
