Article Figures & Data

Figures

  • FIGURE 1.
    FIGURE 1.

    (A) Single-phase CT scan obtained at different hospital does not demonstrate typical arterial enhancement (arrow). (B) Ultrasound image shows hyperechoic mass (arrow). Mass would typically be hypoechoic.

  • FIGURE 2.
    FIGURE 2.

    Axial MR images of area of lesion (arrows). (A) T1-weighted fat-saturated volumetric interpolated breath-hold examination (VIBE) sequence shows typical hypointensity. (B) Arterial-phase T1-weighted VIBE sequence shows no uptake of gadoxetate disodium (Eovist; Bayer). (C) T2-weighted sequence shows typical hyperintensity. (D) Portal venous–phase T1-weighted VIBE sequence shows no gadoxetate disodium uptake.

  • FIGURE 3.
    FIGURE 3.

    18F-FDG PET/CT images of lesion and lymphadenopathy (arrows). (A) Axial (left) and coronal (right) images show liver lesion exhibiting glucose metabolic activity similar to that of surrounding normal parenchyma. (B) Coronal (bottom left and right) images show widespread 18F-FDG–avid lymphadenopathy.

  • FIGURE 4.
    FIGURE 4.

    (A and B) 99mTc-labeled heat-damaged red blood cell images show increased uptake in hepatic (A) and left flank (B) splenule. (C and D) Coronal T1-weighted MR (C) and SPECT/MR (D) images show intrahepatic splenosis in unusual location (arrows).
