24-year-old female with likely from a syndrome with history of breast cancer, glioblastoma and known hepatic metastasis ABDOMEN:LIVER, BILIARY TRACT: Mild loss of signal on the out of phase images consistent with fatty infiltration. Multiple lesions are present within the liver.Two large segment 6/7 and inferior segment 6 lesions are not significantly changed when compared to the prior exam, demonstrating fat saturation, and lacking enhancement compatible with a macroscopic fat containing lesion such as a lipoma. In the location of the previously described homogenously arterially enhancing, inferior right hepatic lobe lesion is a smaller microscopic fat containing lesion that demonstrates mild arterial enhancement and questionable washout. This lesions now measures 13 x 9 mm, previously 15 x 16 mm (series 6, image 34). Several arterially enhancing subcentimeter foci are again seen in segment six, segment seven, and segment eight not significantly changed in size. These lesions demonstrate signal drop on out of phase imaging compatible with microscopic fat. Redemonstrated is a wedge shaped region of postcontrast enhancement in hepatic lobe segment seven that demonstrates mild diffusion restriction and signal drop on out of phase sequence. Status post cholecystectomy.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Status post bilateral mastectomy with susceptibility artifact from prior surgery.OTHER: No significant abnormality noted.
1.Two large lesions compatible with lipomas are unchanged. 2.Intracellular fat containing lesion in the inferior right hepatic lobe with mild arterial enhancement is decreased in size when compared to the prior examination. Continued follow-up of this lesion is recommended. 3.Wedge shaped region on arterial enhancement in hepatic segment 7 also demonstrates intracellular fat and is unchanged in size when compared to the prior examination. 4.Several additional arterially enhancing lesions in the liver as described above also demonstrate signal changes consistent with intracellular fat.
