32 year old female with RLQ abdominal pain. ABDOMEN:LUNG BASES: No significant abnormality notedLIVER, BILIARY TRACT: 4.2 x 3.2 mass in the liver at axial image 39 61 43 with central hypoattenuation displaces adjacent liver parenchyma and vessels. Incompletely characterized on this examination. If clinically indicated, dedicated liver CT or MRI examination may be helpful for further evaluation. This most likely represents focal nodular hyperplasia. No biliary duct dilatation. The hepatic vasculature is intact.SPLEEN: No significant abnormality notedPANCREAS: No significant abnormality notedADRENAL GLANDS: No significant abnormality notedKIDNEYS, URETERS: Multiple foci of hypo-attenuation in the right kidney with lower pole striated nephrogram are seen best on coronal image 51/92 and axial image 63/143. These findings are most compatible with pyelonephritis. No hydronephrosis was found.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality notedOTHER: No significant abnormality notedPELVIS:UTERUS, ADNEXAE: No significant abnormality notedBLADDER: No significant abnormality notedLYMPH NODES: No significant abnormality notedBOWEL, MESENTERY: No significant abnormality notedBONES, SOFT TISSUES: No significant abnormality notedOTHER: No significant abnormality noted
4-cm diameter hepatic parenchymal lesion may be due to FNH, but this examination is insufficient for complete characterization. Right pyelonephritis without evidence of abscess or hydronephrosis.
