We experienced two cases of neurinoma with one located in the tongue, and the other in the lateral cervical region. We herein report the radiographical and MRI findings. The Case 1 was located in the tongue and was suspected to be a malignant tumor with cystic degeneration on an enhanced CT, but the MRI findings showed a low possibility of malignancy because the cystic lesion proved to be an old hemorrhage and the pattern of growth was expansive but not invasive. The Case 2 in the lateral cervical region was at first regarded as an aneurysm by CT. However, the MRI findings showed no appearance of a flow void, and the tumor extended in an upper as well as in a lower direction. Therefore based on the MRI findings the most probable diagnosis was that of a neurogenic tumor. Based on the above findings MRI was thus considered to be useful in the diagnosis of these two cases since a malignant tumor and an aneurysm could be ruled out.
