PATHOLOGY FOR CT REGISTRY
QUESTIONS AND ANSWERS WITH
SOLUTIONS 2024
Vascular lesion characterized by peripheral globular enhancement during initial post
contrast imaging, progressive fill in happens over time, then isodense - ANSWER
Hemangioma
A vascular lesion along the surface of the liver, intense homogenous enhancement, has
a central scar that appears hypodense until delayed imaging - ANSWER Focal nodular
hyperplasia
Most common primary malignant neoplasm of the liver, appears hypodense on non
contrast scans then hyper dense on arterial imaging - ANSWER Hepatocellular
carcinoma
A liver with this demonstrates overall density that is 10 HU less than that of the spleen,
areas of focal sparing of fatty infiltrate appear hyper dense to surrounding tissue and
mimics neoplasm - ANSWER Fatty liver (steatosis)
Chronic destructive disease characterized by hepatomegaly, fatty infiltrate, irregular
nodular contour, and enlargement - ANSWER Cirrhosis
Gall stones - ANSWER Cholelithiasis
Inflammation of the gallbladder - ANSWER Cholecystitis
BIle duct stones - ANSWER Choledocholithiasis
Inflammation of the bile duct - ANSWER Cholangitis
Enlargement of the spleen - ANSWER Splenomegaly
Enlargement of the adrenal glands - ANSWER Adrenal hyperplasia
Calcifications within pelvic veins - ANSWER Phleboliths
Smooth round and thin walled masses with homogenous near water density < 20 HU -
ANSWER Simple Cysts
Complicated cystic masses with densities in the range of 25-90 HU on unenhanced
scans - ANSWER Hyperdense cysts
