Transverse ultrasound
Computed tomography
Magnetic resonance imaging
Gross pathology
HistologyTransverse ultrasound images through the left hepatic lobe show a round, hypoechoic mass (1-2 cm) just below the tip of the lateral segment (within the pancreas). Doppler flow is demonstrated to this mass. Computed tomography images demonstrate that the mass is lower in attenuation than the surrounding pancreatic tissue and is not enhancing. The major vessels are not involved. Both fluid and soft tissue attenuations are present within the lesion. On T1-weighted MRI, the mass is generally iso-intense to the rest of the pancreas (some areas have slightly lower intensity). On T2-weighted images, multiple small, cystic areas are visible. With contrast, peripheral enhancement is evident.
