19 year-old male with right lower quadrant pain. Rule out appendicitis. ABDOMEN:LUNG BASES: No significant abnormality notedLIVER, BILIARY TRACT: Hepatomegaly. The liver measures more than 22 cm craniocaudally. No focal hepatic parenchymal lesions. Gallbladder is normal.SPLEEN: No significant abnormality notedPANCREAS: No significant abnormality notedADRENAL GLANDS: No significant abnormality notedKIDNEYS, URETERS: Right lateral subcapsular renal hematoma probably arises from a right lower pole multiloculated cystic lesion which measures approximately 3.5 by 4.5 cm at axial image 55/152 of series 3. A second similar lesion is in the anterior upper pole of the right kidney measuring 2.6 cm in diameter at axial image 37/152 of series 3. These lesions most likely represent benign angiomyolipomas, but this cannot be confirmed on a post contrast CT scan examination alone. Further evaluation with precontrast noncontrast views of the kidneys and/or MRI of the kidneys would be helpful for further evaluation. The left kidney is normal. No hydronephrosis.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Difficult to identify the appendix with the presence of constipation involving the cecum and ascending colon, but no evidence of abscess, free air or local inflammatory changes.BONES, SOFT TISSUES: No significant abnormality notedOTHER: No significant abnormality notedPELVIS:PROSTATE, SEMINAL VESICLES: No significant abnormality notedBLADDER: No significant abnormality notedLYMPH NODES: No significant abnormality notedBOWEL, MESENTERY: No significant abnormality notedBONES, SOFT TISSUES: L5 vertebral segment is transitional with sacralization on the left side.OTHER: No significant abnormality noted
Subcapsular hematoma in the right renal midpole, probably due to angiomyolipoma. This could be confirmed with noncontrast scan of the kidneys and/or kidney MRI examination. No definite evidence of appendicitis. Hepatomegaly. Transitional L5 vertebral segment, sacralized on the left.
