Case report: Imaging of bile duct hamartomas

MR findings of multiple biliary hamartomas.

“…The MR, CT, sonographic, and angiographic appearances of these malformations have been described previously [3][4][5][6][7]. To our knowledge, this is only the second reported case in which the MR appearance of these lesions is described.…”

“…In our case, sonognams showed a subtle multinodular appearance with alternating hyperechoic and hypoechoic areas. The CT appearance has been reported in five cases [4,5,7]. In all five, multiple irregular hypodense lesions were scattered throughout both lobes of the liver.…”

“…In all five, multiple irregular hypodense lesions were scattered throughout both lobes of the liver. Most of these lesions were 0.5-i .0 cm in diameter, although in one recently reported case, the range was 0.7-3.0 cm [7]. Only one reported case [7] described enhancement of these lesions after IV administration of contrast material.…”

“…In one [4], multiple irregular hypoechoic lesions up to 1 .0 cm in diameter were scattered throughout both lobes of the liver. In another [7], multiple well-defined, rounded, nodular lesions 0.7-3.0 cm in diameter were scattered throughout the liver parenchyma and also were hypoechoic. In the third case, the lesions were hyperechoic rather than hypoechoic; this was attributed to smaller ductubes with crowded interfaces.…”

“…A 50-year-old woman was admitted to the hospital because of fullness in the right upper quadrant of the abdomen, weight loss of 24 lb (10.9 kg), and intermittent fevers (body temperature, 101#{176}F The sonographic appearance has been reported in only three cases [4,6,7]. In one [4], multiple irregular hypoechoic lesions up to 1 .0 cm in diameter were scattered throughout both lobes of the liver.…”
