Original Articles


4 cases of ataxic hemiparesis syndrome are supported by CT proof of a lesion confined to the posterior and superior part of the internal capsule, near the corona radiata. The site of lesion is usually held to be the basis pontis and rostral midbrain. We intend to furnish further evidence in support of an old hypothesis incriminating the corona radiata-internal capsule.


Lacunes ataxic hemiparesis internal capsule corona radiata 


Vengono descritti quattro casi, con conferma TAC, della sindrome di emiparesi atassica, in cui la lesione è localizzata nella parte posteriore e superiore della capsula interna, vicino alla corona radiata. La localizzazione di tale sindrome viene generalmente indicata nella basis pontis e nel mesencefalo rostrale. Noi intendiamo fornire ulteriori prove a sostegno di una precedente ipotesi localizzatrice (corona radiata-capsula interna).
