Computed tomography (CT) was performed in 338 active professional boxers. CT scans were abnormal in 25 boxers (7%). The most common CT abnormality was brain atrophy (22 cases). Focal lesions of low attenuation consistent with posttraumatic encephalomalacia were noted in only three boxers. Boxers with abnormal CT scans did not differ from those with borderline or normal CT scans in regard to age, win-loss record, number of bouts, or history of an abnormal electroencephalogram. Thirty-seven boxers with borderline CT scans (49%) and 17 with abnormal CT scans (68%) reported a previous technical knockout (TKO) or knockout (KO), compared with only 89 (37%) of the 238 boxers with normal CT scans (P < .01). Brain atrophy was noted more frequently in boxers with a large cavum septum pellucidum (CSP) than in those with a small or no CSP (P < .05). Boxers with abnormal or borderline CT scans who experienced a TKO or KO were slightly older than those with normal CT scans and a history of a TKO or KO (P < .05).
对338名现役职业拳击手进行了计算机断层扫描（CT）检查。25名拳击手（7%）的CT扫描结果异常。最常见的CT异常是脑萎缩（22例）。仅3名拳击手发现有与创伤后脑软化相符的局灶性低密度病变。CT扫描异常的拳击手在年龄、胜负记录、比赛场次或脑电图异常病史方面与CT扫描临界或正常的拳击手并无差异。37名CT扫描临界的拳击手（49%）和17名CT扫描异常的拳击手（68%）报告有过技术性击倒（TKO）或击倒（KO）经历，而238名CT扫描正常的拳击手中只有89名（37%）有过此类经历（P <.01）。与透明隔腔（CSP）小或无CSP的拳击手相比，CSP大的拳击手脑萎缩更为常见（P <.05）。经历过TKO或KO的CT扫描异常或临界的拳击手比有TKO或KO病史且CT扫描正常的拳击手年龄稍大（P <.05）。
