Diagnosis: Obstructive urolithiasis with calyceal rupture

Average Case-Specific Score: 3.27 / 6

Answer Key

Sample Preliminary Report

6 mm calculus in the distal left ureter with associated mild left hydroureteronephrosis and large volume low-density left perinephric fluid concerning for calcyceal rupture. Recommend urologic evaluation.

Urothelial thickening involving the left renal pelvis and proximal left ureter may relate to the impacted calculus; however, recommend correlation with urinalysis for signs of urinary tract infection.

Long segment mural thickening of the sigmoid colon and rectum, concerning for infectious or inflammatory proctocolitis. No evidence of bowel obstruction.

Moderate-sized hiatal hernia with layering fluid.

Several hypoattenuating lesions in the liver, which are nonspecific but could represent metastatic lesions in this patient with reported history of carcinoid tumor. DOTATATE-PET could provide further evaluation.

Linear metallic fragments in the liver near the hepatic dome, likely retained from a prior intervention.

Findings/impression:
Retroperitoneal fluid is present surrounding the left kidney and may represent a retroperitoneal hematoma, however ureteral injury is also considered. Recommend correlation with Hounsfield units. Recommend multi phase imaging for further evaluation if there is continuing clinical concern after the previous recommendations.
Multiple mixed density bilateral renal cysts are present. Recommend evaluation with computed units and multiphasic CT for further evaluation. Neoplasm cannot be excluded.
Mild periportal edema. Hypodensities are present within the portal veins. This could represent thrombus, however contrast mixing is more likely. Recommend multiphase imaging for further evaluation if there is continued clinical concern.
Indistinct hypodensities are present in the liver and most prominent along the right anterior liver. This could represent neoplasm.
Hyperdense surgical material is within the liver.
Calcifications are present within the breasts. Asymmetric breast tissue is present with increased tissue on the left. Attention on follow-up.
Moderate hiatal hernia with fluid places the patient at risk of aspiration..
A gastric polyp versus lipoma is present within the hiatal hernia.
Surgical changes of the colon are present. Recommend correlation with patient’s clinical history.
Diverticulosis without frank diverticulitis.
Mild colonic wall thickening with minimal surrounding inflammatory changes could represent mild infectious/inflammatory colitis in the proper clinical setting. Recommend correlation with patient’s symptoms and labs.
Posterior soft tissue hypodensities are present in the represent fat necrosis.
S shaped curvature of the lumbar spine. Spondylosis.

Diverticulosis without diverticulitis. No bowel obstruction. Appendectomy.
Small fat containing periumbilical hernia.
Multiple nodules of the subcutaneous gluteal tissues bilaterally, favored injection granulomas.
L4 vertebral venous malformation.
Partially calcified nodularity along the anterior T12-L1 intervetebral space, suspicious for neoplasm. Consider PET CT for further evaluation.
