Can MRI detect hemangioma?
Table of Contents
MR imaging findings in hemangioma are frequently diagnostic. On T2-weighted images, hemangiomas generally appear as multiple high-signal-intensity lobules that resemble a bunch of grapes (,,,,,Fig 12c). This appearance is due to cavernous or cystic vascular spaces containing stagnant blood.
What does a spinal hemangioma look like on an MRI?
The stereotypical hemangioma usually causes no problems, because on MRI it appears hyperintense (bright) on T1- and T2-weighted images and enhances intensely on postcontrast T1-weighted, fat suppressed images. These lesions are sharply demarcated (2).
How is spinal hemangioma treated?
Treatment for hemangiomas depends on the size and location of the tumor. At UPMC, we use a combination of stopping blood flow to the tumor (embolization), surgical removal of the tumor, and radiation therapy. Radiation therapy is effective in the treatment of pain caused by hemangiomas.
Can spinal hemangiomas be misdiagnosed?
Unfortunately, not all hemangiomas have the typical appearance, and they can mimic metastases on routine MR imaging. These are generally referred to as atypical hemangiomas and can result in misdiagnosis and ultimately additional imaging, biopsy, and unnecessary costs.
Are hemangiomas hot on bone scan?
The variable appearance of hemangiomas on CT can make diagnosis difficult. Additionally, while generally regarded to be “cold” appearing on bone scan, hemangiomas have been reported to be “hot”, with increased radiotracer uptake [2,8].
What causes hemangiomas on the spine?
Hemangiomas, Benign: Hemangiomas are non-cancerous (benign) tumors made of abnormal blood vessels. They are common and can occur anywhere in the body. Most hemangiomas of bone are in the spine and are found more often with advancing age.
Can vertebral hemangiomas be malignant?
The diagnosis of vertebral hemangioma is very crucial and can be challenging in some cases. It may mimic malignant lesions in both clinical and radiological behavior [7]. Hemangiomas can be aggressive, compressing the spinal cord with paraparesis and spasticity as in our case.
Can you have a hemangioma on your spine?
Spinal hemangiomas usually develop in the bones of the spine, known as vertebrae. Most vertebral hemangiomas are located in either the thoracic (upper- to mid-) or lumbar (lower) spine. Only rarely are they found in the cervical spine (neck). Spinal hemangiomas are widespread: they are present in about 10% of people.
Can a spinal hemangioma become malignant?
