回顾了 19 名部分复杂性癫痫发作和经手术证实的脑内神经节胶质瘤患者的临床和放射学结果，以表征这些病变的放射学特征。 CT 和 MR 结果并不具体。在 CT 上，神经节胶质瘤可能呈低密度，无强化，并且常常有钙化。在 MR 上，这些肿瘤有各种各样的信号。在我们的 5 个病例中，肿瘤在质子密度和 T2 加权图像上具有高强度信号，并带有囊肿样成分。在 5 个病例中，病变在质子密度加权图像上具有不均匀的强信号，而在 T2 加权图像上具有高信号强度。 4 名患者的肿瘤在质子密度加权图像和 T2 加权图像上均具有高强度信号。最后，在两个病例中，MR 结果正常。我们建议 MR 作为部分复杂性癫痫患者的首选检查方法，因为它可以对颞区进行无伪影的评估。然而，还应该进行 CT 检查，以识别 MR 检查中可能漏掉的钙化点。
The clinical and radiologic findings in 19 patients with partial complex seizures and surgically proved intracerebral gangliogliomas were reviewed to characterize the radiologic features of these lesions. The CT and MR findings were not specific. On CT the gangliogliomas can be hypodense with no enhancement and they often have calcifications. On MR these tumors have a wide variety of signals. In five of our cases the tumor had a high-intensity signal with a cystlike component on proton density- and T2-weighted images. In five cases the lesion had an inhomogeneously intense signal on proton density-weighted images and high signal intensity on T2-weighted images. The tumor had high-intensity signal on both proton density- and T2-weighted images in four patients. Finally, in two cases the MR findings were normal. We recommend MR as the examination of choice for patients with partial complex seizures because it allows an artifact-free evaluation of the temporal region. However, CT should also be performed in order to recognize calcifications that may be missed on the MR examination.
