ABSTRACT
Objective To investigate the characteristic clinical, imaging, and pathologic findings of intracranial neuronal and mixed neuronal-glial tumours. Methods The imaging findings of surgery and pathobiology proved intracranial neuronal and mixed neuronal-glial tumours in 14 cases (7 male and 7 female, ranging in age from 6-56 years; mean age 33.8 years) were retrospectively analyzed. Results Eight gangliogliomas were located in the frontal lobe (4 cases), temporal lobe (1 case),fronto- temporal lobe(2 cases), and pons (1 case). They appeared as iso-or low density on CT, iso-or low signal intensity on T 1WI, and high signal intensity on T 2WI on MR imaging. Two central neurocytomas were located in the supratentorial ventricles. Four desmoplastic gangliogliomas were seen as cystic masses, appearing as low signal intensity on T 1WI and high signal intensity on T 2WI Conclusion Intracranial neuronal and mixed neuronal-glial tumours had imaging characteristics. Combined with clinical history, it was possible to make a tendency preoperative diagnosis using CT or MR.
