We report a case study of a frontal and parietal lobe syndrome with memory
loss after unilateral left-sided cerebellar damage caused by a stroke in a
patient with right cerebellar unusual developmental agenesis. The syndrome
consisted of severe deficits in planning an organized sequence of events, i
n visuo-constructive abilities and inappropriate jocularity. These changes
are ascribed in part to cerebellar-pontine lesions with resulting frontal l
obe diaschisis as documented by single-photon emission computed tomography
in the absence of morphological damage to the neocortex.
