Studies show that ultrasound is about 80 percent accurate in detecting hemangiomas. CT may be a more accurate modality in this case. I would suggest that if the hemangioma isn't seen by CT, then it probably isn't there.
MRI is emerging as the most accurate study and you may want to consider this if you have any doubt.
Followup with your personal physician is essential.
