Abstract
MR imaging features of 11 primary tumors of the trigeminal nerve and Meckel's cave were analyzed. The tumors consisted of two trigeminal schwannomas, five meningiomas, one lipoma, and three epidermoid tumors. The trigeminal schwannomas had homogeneously decreased signal intensity on T1-weighted images and increased signal intensity on T2-weighted images. Three of the five meningiomas had signal intensity similar to that of surrounding brain on both T1- and T2-weighted images. One meningioma had decreased signal intensity on T1-weighted images and increased signal intensity on T2-weighted images. The other had relatively low signal intensity on both T1- and T2-weighted images owing to heavy calcification demonstrated on CT. The lipoma had homogeneous signal intensity that was isointense with orbital and subcutaneous fat on both T1- and T2-weighted images. The epidermoid tumors had decreased signal intensity on T1-weighted images and markedly increased signal intensity on T2-weighted images. In addition, the epidermoids had an insinuating growth pattern and minimal mass effect. The extent of involvement in the trigeminal nerve distribution was well demonstrated in each case. Because of its multiplanar capability, exquisite anatomic detail, and characteristic tissue signal intensity, we conclude that MR is helpful in the differential diagnosis of primary tumors of the trigeminal nerve and Meckel's cave and in the evaluation of tumor involvement for preoperative planning.
