A hemangioma in the right lobe of the liver that will not go away on its own. Hemangiomas are generally considered to be congenital lesions that result from abnormal development of small blood vessels within the liver. If a hemangioma was present on a previous exam and not found on another exam, it is most often shown as a false negative due to changes in blood volume of blood vessels within the liver, which affects the ultrasound presentation of the hemangioma. The patient can have another imaging test, such as a CT scan of the liver or an MRI, which can usually find the hemangioma. Most patients with hemangiomas do not have any symptoms and are found incidentally during imaging. Therefore, for relatively small hemangiomas, patients only need to review the ultrasound regularly to observe the changes of the hemangioma; if the hemangioma is large and the patient has symptoms such as abdominal discomfort, interventional and surgical treatments can be considered.
