Cavernous hemangioma is common in the head and neck region, and pathologically cavernous hemangioma characterized by small feeding arteries and large blood pools.
Angiography and computed tomography have not demonstrated the whole extension of these lesions. 9 patients with cavernous hemangioma were evaluated with magnetic resonance imaging in this study. MRI could clearly demonstrate cavernous hemangiomas with good contrast to normal tissues.
Cavernous hemangiomas showed losv-iso signal intensity compared to the muscle on the Ti weighted image and isu-high signal intensity on T2. All cases did not show a flow void on the proton density image that is most sensitive to flow, and were enhanced by Gd-DTPA.
Especially, T2 weighted and Gd-DTPA enhanced images were useful to demonstrate these lesions.
Intramuscular cavernous hemangiomas in the head and neck region were characterized by local muscle atrophy and septum formation.
