| Abstract;Cavernous hemangioma is a common benign tumor in the head and neck region. It is essential to determine the anatomical confinements and blood supplies of hemangiomas to select and plan treatment procedures. Computed tomography and angiography have been employed to diagnose hemangiomas and the use of MRI was recently reported. We report two patients who underwent MRI for diagnosing hemangioma in the buccal region. The signal intensity in these tumors was less than that of subcutaneous fat on T1-weighted images. On the other hand, T2-weighted signal intensity on the tumor was greater than that of fat. T2-weighted images were effective to visualize these cavernous hemangiomas. Two cavernous hemangiomas showed a septation pattern that revealed low signal intensity on T2-weighted images and the T1 signal of the septum increased in contrast to that of the surrounding area. We report two patients with unique findings that might be useful to depict feeding and/or draining vessels in cavernous hemangioma. (author abst.) |
