Value of ultrasound and color Doppler imaging in children orbital tumors / 眼科研究

ABSTRACT

Objective Imageology diagnosis of orbital tumor is very critical for the determination of nature of tumor in childhood patients. It is very necessary to comprehensively assess the results of clinical manifestations and imageology for the identification of orbital tumor. This study was to evaluate the clinical value of ultrasonography and color Doppler imaging (CDI) in the diagnosis of orbital tumors in children. Methods The clinical data, B-type echograms and CDI of 39 children with orbital tumors including capillary hemangioma, lymphangioma, venous hemangioma, rhabdomyosarcoma, dermoid cyst, varicosity etc. Were analyzed retrospectively. Results Among 39 cases of orbital tumors in children, 8 cases of capillary hemangioma and 2 cases of rhabdomyosarcoma showed the signals of artery blood flow from CDI ultrasound examination. No blood flow signal was obtained in 12 cases with dermoid and 8 cases with lymphangioma. The venous blood flow signals were examined from CDI examination in 3 out of 6 cases of venous hemangioma. Dynamic blood flow changes were seen from CDI in 3 cases with varicosis. Conclusion Combination of B-type ultrasonography and CDI is useful for the diagnosis of orbital tumors in childhood patients.
