I.はじめに
小児頭部外傷では,成人と異なり,局所神経症状よりも,むしろ頭痛,嘔吐,不機嫌,貧血等,全身症状が前景に出ることが多い.したがって臨床症状のみから頭蓋内血腫や脳挫傷の存在を早期に診断することは困難な場合が少なくない.このような場合,無侵襲のCTが診断上極めて有用であることはいうまでもない.
本研究では,15歳以下の小児頭部外傷について,急性期から慢性期にいたるCT像を臨床所児,脳波所見等と比較した.
Findings of computerized tomography (CT) in 183 cases of head injury in children were investigated with special reference to CT findings of mild head injury.
As was expected, CT findings of mild head injury fell within the normal range, in almost all cases. However, abnormal findings were noticed in 4 out of 34 cases (12%) in acute stage and 7 out of 76 cases (9%) in chronic stage. They were 3 cases of localized low density area in acute stage and 6 cases of mild cerebral atrophy in chronic stage, etc. There were some cases of mild head injury in which CT findings were normal while EEG examination revealed abnormality.
