The image characteristics and the clinical and pathological diagnosis of gliomatosis cerebri / 中国医师进修杂志

ABSTRACT

ObjectiveTo explore the imaging characteristics and the clinical and pathological diagnosis of gliomatosis cerebri in order to raise the awareness of the disease.MethodsThe images of 26 patients with gliomatosis cerebri were analyzed retrospectively.ResultsEight patients were treated with partial excision and 18 patients got stereotactic biopsy.The radiography examination included the plain and enhanced scan of CT and MRI.Twelve patients received 1H magnetic resonance spectroscopy (MRS).The disease in all the patients involved at least two cerebral lobes.There were 22 cases whose CT and MRI manifestations showed that there were large-sheet symmetry low-density image in brain and slightly long T1 and long T2 abnormal signals.And the enhanced scan showed that 20 cases had no obvious enhancement,2 cases had slight enhancement.There were 4 cases with large-sheet asymmetry lesions and no enhancement in enhanced scan.1H MRS examination of 12 cases showed that choline( CHO )/creatine(Cr) and CHO/N-acetyl aspartic acid (NAA) increased,NAA/Cr decreased with different degree,and 8 patients had lactate peak.ConclusionsMRI is the first choice to diagnose gliomatosis cerebri.1H MRS is very helpful for the diagnosis and pathological classification of the disease.MRI combined with biopsy can give out a definite diagnosis.
