ABSTRACT

Objective To improve the diagnosis of germinomas in basal ganglia area by analysing the imaging manifestations.Methods Clinic,pathologic and medical imaging data of 8 cases of germinomas in basal ganglia area confirmed pathologically were analyzed retrospectively.Results 8 cases were all men,the age ranged from 5~13 years old with mean age of 10.5 years.All cases had change of muscle strength on one side of extremity,and one case accompanied by intracranial hypertension,this case was showed the effect of space occupying of the tumor obviously and hydrocephalus on CT and MRI.The findings of CT and MRI showed cystic degeneration in 4 cases,slight edema around the tumor in 2 cases,cortex atrophy of the same side of tumor in 2 cases and calcification in the tumor in 2 cases.All cases were enhanced greatly.The pathologic specimen with rich supply of blood was gray-red,and cystic degeneration was seen in 4 cases.Conclusion CT and MRI features of germinomas in basal ganglia area are quite characteristic,the improvement of diagnosis can be achieved in combination with clinical manifestation.
