[Low grade XXXX : pathological and magnetic resonance findings].

@entity1 @entity5 @entity10053 @entity892 @entity10 @entity1621
INTRODUCTION: The @entity10053 is an uncommon type of @entity5 . It accounts for less than 1% of all @entity5 of the central nervous system. It originates in the tanicytes, ependymal cells present in the embryo and usually seen in adolescents and young adults. Radiologically it presents as a well delimited, @entity5 with a solid component which takes up contrast and is cystic, giving the same signal as cerebrospinal fluid (CSF). The pathological characteristics are of the formation of radial astroblastic pseudorosettes with perivascular hyalinization. CASE REPORT: An 18 year old @entity1 presented with a 15 month history of motor deficit of her right limbs with occasional left frontal @entity10 and horizontal @entity892 on looking towards the left. On examination there was minimal claudication of the right limbs and @entity1621 . Magnetic resonance showed a very well circumscribed left prefrontal @entity5 of heterogeneous aspect, with areas of solid and cystic appearance in the different sequences. The area of cystic appearance did not show the CSF signal in all sequences of the pulse. The @entity5 was totally excised. On histological study there were radial astroblastic pseudorosettes with perivascular hyalinization, with two mitoses per 10 fields of great magnification and the final diagnosis was of low grade @entity10053 . The apparently cystic portion was composed of friable gelatinous tissue. Fifteen months after her operation the @entity1 is still asymptomatic. CONCLUSION: We report the radiological and pathological findings of a low grade @entity10053 .
