| Abstract | 「要旨」脳梗塞の亜急性期, 慢性期にN-isopropyl-p[I-123]iodoamphetamine(I-123 IMP)を用いたSPECT検査を施行したところ興味ある所見を呈したので文献的考察を含め報告する. 症例は81歳男性, 左中大脳動脈領域の脳梗塞で心房細動の既往があった. 発症後12日目のSPECTでは梗塞巣に強い集積を認め, 対側小脳はcrossed cerebellar diaschisis(CCD)による血流低下を示した. 同時期に施行したX線CTでは, 梗塞部位にfogging effectおよび著明な造影効果を認めた. 発症後61日目に施行したSPECTでは同部位は完全な集積低下を示した. 亜急性期の梗塞巣へのI-123 IMP集積はhyperemiaを検出したものと考えられ一方CCDはその原因病変の代謝の低下を示唆するため, この2つの所見は梗塞巣の代謝を上回る血流増加“luxury perfusion”を脳血流断層像より推察させるものであった. またテント上病変集積亢進, 対側小脳集積低下は, CCDの画像所見として特異な一型と考えられた. |

| Abstract | SPECT with N-isopropyl-p-[I-123]iodoamphetamine were performed in a 81-year-old man with cerebral infarction. In the subacute phase, the radioactivity was increased in the infarct area where fogging effect and remarkable contrast enhancement was demonstrated in X-ray CT. The contralateral cerebellar hemisphere showed reduced activity due to crossed cerebellar diaschisis (CCD). In the chronic phase, the decrement of the activity in the infarct was observed. Increased activity in the subacute phase was thought to reflect the hyperemia in the infarct, while CCD suggested the decreased metabolic activity in the lesion. The coexistence of the hyperemia and the CCD indicates flow and metabolic uncoupling, which means "luxury perfusion". This case was also thought to demonstrate atypical findings of CCD in SPECT imaging. |
