sies on XT patients with L’2 ( 18%) showittg massive sickling and cerebral infhrcts. 1.3 (13%) having massive sickling of cerebral vessels withour proven infitrcts. and the remaining 83 (69%) containing multiple vessels with sickled cells but no impactions. Thus , 30% of. S(ZpI‘patients had signiticant sickling and may have had central net-votes system symp totns. Patients with SCJ‘ have had slow, progressive infarction of‘ the ftraiti and sf)irtaf cod,"? f>ituitnr!;. and retina.“’ Hemoglobin AS is ttot an innocuous ~enotvpe. Karl\ et al’ 1 have recentfv shown 2111 increased itt&len& of’ sucfdett death in SCT re&tits. High altitude encatnpn~et~t, exercise, and flying without comf)ressiott are acceflted causes of sickling in heterozygous disease. Many military personnel are exposed to all three of‘ cite above hazards. The visual hallucinations without paranoid ideation were a cfue to sickling.

Subcortical white tnatter in the occipital pole is most frequently involved,” and is the most logical site for \,isual hallucinations of’ organic origin. Frontal pole, centrum ovalr, internal capsule, and potts follow in descending order of‘ fl-ecfuency as sites of’ isc-ltemia and infarction.
