There was no lymph node enlargement (Fig. 2).
Abdominal magnetic resonance imaging and Positron emission tomography.. A. The tumor exhibited low signal intensity on T1-weighted images. B. The tumor exhibited high signal intensity on T2-weighted images. C. The tumor exhibited high signal intensity on diffusion weighted images. D. Positron emission tomography revealed a maximum standardized uptake value of 5.4 in the tumor.

Abdominal magnetic resonance imaging revealed low signal intensity on T1-weighted images, high signal intensity on T2-weighted images, and high signal intensity on diffusion weighted images (Fig. 3A-C). Positron emission tomography revealed a maximum standardized uptake value of 5.4 in the tumor (Fig. 3D).
Hepatobiliary scintigraphy.. A. There was no delayed excretion in the liver, but retention in the blind loop of the choledochojejunostomy was retarded and the excretion was delayed. B. Stasis in the blind loop was improved.

Hepatobiliary scintigraphy revealed that there was no delayed excretion in the liver, but retention in the blind loop of the choledochojejunostomy was retarded, and the excretion was delayed (Fig. 4A). Postoperative hepatobiliary scintigraphy was performed to confirm improvement of stasis in the blind loop (Fig. 4B).
