三叉神经瘤１４例，１２例做ＣＴ检查，２例做ＭＲＩ检查，１４例术后均经病理检查证实。１２例ＣＴ扫描呈混杂密度６例，均匀高密度５例，等密度１例，注射造影剂后多呈不均匀强化，肿瘤周围均无脑水肿。２例ＭＲＩ图像Ｔ１加权像呈低信号，Ｔ２加权像呈高信号。Ｘ线平片示１１例有岩骨、颅底骨吸收破坏。临床常伴有听神经、面神经等受累。ＣＴ和ＭＲＩ是诊断三叉神经瘤的有效检查方法。三叉神经瘤应与脑膜瘤、胶质瘤及听神经瘤等相鉴别。
Trigeminal neuroma in 14 cases, 12 cases of CT examination, 2 cases of MRI examination, 14 cases were confirmed by pathological examination. Twelve CT scans showed mixed density in 6 cases, uniform high density in 5 cases and equal density in 1 case. Most of them were non-uniformly intensified after injection of contrast medium and had no cerebral edema around the tumor. Two cases of MRI image T1 weighted image was low signal, T2 weighted image was high signal. X-ray showed 11 cases of petrous bone, skull base absorption damage. Often accompanied by clinical auditory nerve, facial nerve involvement. CT and MRI are effective methods for the diagnosis of trigeminal neuroma. Trigeminal neurinoma should be differentiated from meningioma, glioma and acoustic neuroma.
