硬膜下血腫と両眼に大量の網膜前出血を合併した乳児の1例

An infant with subdural hematoma and massive preretinal hemorrhage in both eyes

要約　生後5か月の女児が母親の腕から机の上に落ち頭部を打撲した。3日後に痙攣発作が生じた。頭部CT検査で硬膜下血腫と診断され保存的に処置された。その7日後の眼底検査で，両眼の後極部に多量の網膜前出血があった。出血は徐々に消退し黄斑部の色調が1か月後に正常化した。網膜前出血は頭部の打撲によるshaken baby syndromeである可能性がある。

Abstract.　A 5-month-old female infant slipped from her mother's arms,and had her head hit by the top of a table. Convulsive attacks occurred 3 days later. Computed tomography（CT）showed subdural hematoma. She was treated conservatively. Funduscopy 7 days later showed massive preretinal hemorrhage in both eyes. The hemorrhage gradually became absorbed. The macular area regained visibility and normal appearance one month later. The observed preretinal hemorrhage may be a manifestation of shaken baby syndrome.
