Cavernous hemangioma is common in the head and neck region, and pathologically cavernous hemangioma characterized by small feeding arteries and large blood pools.<BR>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.<BR>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.<BR>Especially, T2 weighted and Gd-DTPA enhanced images were useful to demonstrate these lesions.<BR>Intramuscular cavernous hemangiomas in the head and neck region were characterized by local muscle atrophy and septum formation.
