Fig. 1B. 39-year-old woman with 12-cm focal nodular hyperplasia in
right liver (segments VI and VII). Coronal time-of-flight MR angiogram shows
subcapsular collateral pathway (arrows) between middle and right
hepatic veins.

Fig. 2A. 40-year-old woman with 10-cm focal nodular hyperplasia in
liver segment I. Arterial phase contrast-enhanced CT scan shows strongly
enhancing mass in segment I with central scar (arrowhead).

Fig. 2B. 40-year-old woman with 10-cm focal nodular hyperplasia in
liver segment I. Portal phase contrast-enhanced CT scan at same level as
A shows obstruction of middle hepatic vein, associated with
intrahepatic (arrow) and subcapsular (arrowhead) venous
pathway between middle and right hepatic veins.

Fig. 2C. 40-year-old woman with 10-cm focal nodular hyperplasia in
liver segment I. T2-weighted MR image shows isointense mass with central
hyperintensity corresponding to central scar (arrowhead). Inferior
vena cava is compressed by mass (arrow).

Fig. 3A. 42-year-old woman with 4-cm focal nodular hyperplasia located
centrally in liver. Sonogram reveals isoechoic mass (arrowhead) in
segments II, IV, and VIII that obstructs middle hepatic vein
(arrow).

Fig. 3B. 42-year-old woman with 4-cm focal nodular hyperplasia located
centrally in liver. Sonogram obtained at level below A shows
intrahepatic venous collateral pathway (single solid arrow) between
middle (double solid arrows) and right (open arrow) hepatic
veins.

Fig. 3C. 42-year-old woman with 4-cm focal nodular hyperplasia located
centrally in liver. Sonogram obtained in more cranial section than B
clearly shows distal segment of intrahepatic venous collateral pathway
(solid arrow). Pathway drains into right hepatic vein (open
arrow).

Fig. 3E. 42-year-old woman with 4-cm focal nodular hyperplasia located
centrally in liver. T2-weighted MR image shows slightly hyperintense lesion in
central liver that obstructs middle hepatic vein (curved arrow). Note
calcified central scar (straight arrow).

collateral pathway between middle and right hepatic veins
(arrow).
