PURPOSE : To investigate the association between the size of the hepatic hemangioma and the shape and thickness
of the echogenic rim of hepatic hemangionma on abdominal ultrasound.
MATERIALS and METHODS : We examined 47 cases (M:F=24:23. mean age 47.1) of hepatic hemangiomas with echogenic
rim on abdominal ultrasound during the past 2 years. Radiologic findings were retrospectively reviewed
in terms of completeness and thickness of echogenic rim. If echogenic rim showed even thickness, it
was measured. But if not, the maximum and minimum thickness of the rim was measured. The association between
the size of hemangioma and the completeness and thickness of the echogenic rim were analyzed statistically.
RESULTS : Of the 47 cases, complete echogenic rim and incomplete echogenic rim were obtained in 29 (62%) and
18 (38%) cases, respectively. Twenty-two cases of hemangioma were less than 2 cm in diameter, and their distribution
according to echogenic rim were as follows: complete echogenic rim (17/20, 91% mean thickness
2.2 mm) and uneven thickness with complete echogenic rim (3/20, 15%, range:2.0 - 6.1 mm). Twenty-five hemangiomas
were larger than 2 cm in diameter and their distribution according to echogenic rim were as follows:
complete echogenic rim (n=9, 34%), incomplete echogenic rim (n=16, 64%), even thickness with complete echogenic
rim (3/9, 33%, mean thickness 2.2 mm) and uneven thickness with complete echogenic rim (6/9, 67%,
range:2.0 - 7.6 mm). In statistical analysis, hemangiomas more than 2 cm in diameter were more likely to have
incomplete echogenic rim (p<0.05) than those of less than 2 cm; hemangiomas more than with more than 2 cm
in diameter and complete echogenic rim showed uneven thickness of echogenic rim (p<0.05), more often than
those of less than 2 cm in diameter.
CONCLUSION : Hemangiomas with more than 2 cm in diameter showed more frequent incomplete echogenic rim
than those of less than 2 cm in diameter, which had more frequent complete echogenic rim. Hemangiomas with
complete echogenic rim and even rim thickness were more prevalent in those with less than 2 cm in diameter.
Uneven rim thickness was present more often in those with more than 2 cm in diameter |
