Abstract |
We evaluated the scintigraphic findings of
sonographically atypical hemangioma, that is, a
hypoechoic or heterogeneously hypoechoic nodule which
contains hypoechoic areas more than 40% of the volume,
and compared it with those of sonographically typical
hemangioma in 26 patients with 31 nodules.
Sonographically atypical hemangioma were 13 in 11
patients and sonographically typical hemangioma were 18
the 15 patients. Dynamic blood flow, planar and SPECT
blood pool imaging was performed. In atypical
hemangioma, increased blood pool activity was seen in
11 of 13 nodules on SPECT and in 10 of 13 nodules on
planar image and increased blood flow was seen in 4 of
13 nodules on dynamic blood flow study. No significant
difference in detecting increased blood pool activity
between sonographically atypical and typical
hemangioma. In conclusion, Tc-99m-red blood cell SPECT
is as useful in diagnosis of sonographically atypical
hemangioma as in typical hemangioma and can be used as
a confirmatory or complementary study. |
