MR Imaging Diagnosis of the Intracranial Ganglioglioma / 实用放射学杂志

ABSTRACT

Objective To eveluate the value of magnetic resonance (MRI) in diagnosis of the intracranial ganglioglioma.Methods To retrospectively analyze the clinical and the imaging materials of 4 cases intracranial ganglioglioma proved by operation and pathology. Four patients including 2 males and 2 females , aged 14～47 years, mean 27years were studied.Results 4 cases intracranial ganglioglioma were located in right temporal lobe(2 cases), left frontal lobe(1 cases) and the cerebellum lobe(1 cases). 3 cases were cyst-solid mass and one cases were predominantly cystic. There were no evidently edema around the tumor .The cystic place of the tumor was hypointense and the rampart-nodule of the tumor was slightly hypointense. Gd-DTPA enhanced scan showed surround enhancement and nodular areas of contrast enhancement along their margins. On the T 2-WI, all lesions were hyperintense.Conclusion Ganglioglioma is rarely tumor in central nervous system and it lacked peculiar findings of imaging . It may be the ganglioglioma when the patient's aged is a young man or woman, the tumor locate temporal lobe or the cerebellum, the tumor is cystic or cyst-mass neoplasm and it is demonstrated laminar or nodular areas of contrast enhancement along their margins.
