Blockage Affects:

Main symptoms are ipsilateral cerebellar ataxias ( middle and/or superior cerebellar peduncles ), nausea and vomiting, slurred (pseudobulbar ) speech, loss of pain and temperature over the opposite side of the body. Partial deafness, tremor of the upper extremity, an ipsilateral Horner syndrome and palatal myoclonus have been reported. Clinically, this stroke may be impossible to distinguish from a partial AICA or PICA territory stroke. It is much rarer than either one. Ocular pulsion away from the side of lesion has been reported in SCA syndrome. Diagnosis is via MRI.
