CT diagnosis of infantile beriberi(an analysis of 87 cases)

Objective:To discuss CT findings of infantile beriberi so as to improve the diagnostic accuracy.Methods:CT manifestations and characteristics in87cases of infantile beriberi proved by clinical treatment and follow up were studied ret-rospectively.CT scanning methods included plain scan and contrast enhancement.Results:CT plain scan showed bilateral symmetrical hypodense of lentiform nucleus and the head of caudate nucleus in79cases,and in8cases only the lentiform nucleus were involved.The other accompanying signs were the compression on the anterior horn of bilateral ventricles in79cases,external hydrocephalus in37,bilateral subdural fluid accumulation in15,the bilateral symmetrical hypodense lesions of tem poroparietal lobes in3.Fifteen patients were studied by enhancing scans,the lesions were not enhanced.Thirty-nine cases had follow-up CT plain scan and10patients had sequelae,among whom7were found to have the remaining bilateral sym-metrical saccular-lineal hypodense lesions,and the lesions of the other32patients almost disappeared.Conclusion:Correct di-agnosis of infantile beriberi can be made by characteristic CT findings combined with clinical data.CT follow-up provides im-portant evidence for estimating recovering.
