APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Ataxic hemiparesis (AH), which is characterized by both ipsilateral ataxia and paresis, was first described by Fisher in 1965. A 1978 revision expanded the definition of AH to include any combination of weakness and disproportionate incoordination presenting on the same side of the body (1, 2).

Detailed explanation-2: -Ataxic hemiparesis: These patients present with unilateral limb ataxia and weakness that is out of proportion to the strength/motor deficit. Patients may also exhibit other ipsilateral cerebellar signs, such as dysarthria, dysmetria, and nystagmus, without exhibiting cortical signs.

Detailed explanation-3: -Ataxic hemiparesis (AH) is characterized by the simultaneous presence of a pyramidal tract syndrome with homolateral ataxic syndrome. In the first description of AH by Fisher and Cole (1965), they elaborated the core symptoms as weakness and pyramidal signs on one side combined with ipsilateral cerebellar-like ataxia.

Detailed explanation-4: -ATAXIC HEMIPARESIS IS an unusual clinical syn-drome first described by Fisher and Cole, 1 where there is weakness and ataxia on the same side. Since then there has been 10 cases reported, where it has been possible to localize the site of the lesion pathologically or by means of computed tomography.
