Abstract :

Statement of the Problem: Orbital cavernous venous malformation (used to be known as "orbital cavernous hemangioma") is one of the common orbital occupancies, it is not a neoplasm but a venous malformation. Vision and appearance may be affected by the mass effect masses, such as blurred vision and exophthalmos may be caused by eyeball pushing. Orbital cavernous venous malformation usually present as a mass solitary, with well-defined margin, sometimes it is difficult to be identified with some tumors, such as schwannoma, solitary fibrous, and pleomorphic adenoma. The application of contrast-enhanced ultrasound imaging technology has become more and more extensive and mature recently, but there were few studies on orbital cavernous venous malformation. This study aims to help improve the diagnostic accuracy by analyzing the enhanced manifestations of orbital cavernous vascular malformation. The purpose of this study is to improve the ultrasound diagnostic accuracy of orbital cavernous vascular malformations by analyzing the enhanced features of contrast-enhanced ultrasound. Methodology & Theoretical Orientation: The contrast-enhanced ultrasound findings of orbital cavernous venous malformation cases were reviewed and analyzed to find the characteristics. Findings: All cases showed nodular contrast enhancement after injection of contrast agent, and these nodules grew larger progressively over time. Compared with surrounding tissues, the enhancement of cavernous venous malformations were usually later or synchronous. Conclusion & Significance: Contrast-enhanced ultrasound of orbital cavernous venous malformation has typical characteristics, and it is helpful for qualitative diagnosis.
