Abstract:
Objective To explore the value of conventional and contrast‐enhanced ultrasound(CEUS) in the diagnosis of tumors in front of the orbit equator . Methods Clinical data included conventional ultrasound and CEUS image of 133 cases (156 eyes) with orbital lesions were analyzed retrospectively . All lesions were confirmed by surgical pathology or clinical cure ,which included 26 cases of cystic lesions (epidermoid cysts ,dermoid cysts ,sebaceous cysts and mucous cysts) ,29 cases (30 eyes) of orbital hemangioma ,13 cases ( 16 eyes ) of inflammatory pseudotumor ,11 cases of lacrimal gland pleomorphic adenoma ,3 cases (5 eyes) of lymphoepithelial lesion ,36 cases (53 eyes) of malignant lymphoma ,5 cases of meibomian gland carcinoma ,4 cases of lacrimal gland adenoid cystic carcinoma ,3 cases of malignant melanoma and 3 cases of basal cell carcinoma . Results CEUS of benign cystic lesions showed the tumors were enhanced inhomogenously . Most CEUS of benign tumours displayed?slow in and slow out ,and high enhancement when reached the peak but the size of images had no change . While CEUS of malignant tumours showed?fast in and fast out ,homogeneous or inhomogeneous high enhancement and ill‐defined or irregular shape ,and volume increased compared to two‐dimensional ultrasound when reached the peak .Some other former district orbital lesions ,such as cystic lesion ,cavernous hemangioma ,pleomorphic adenoma and malignant lymphoma ,had their own ultrasound features . Conclusions CEUS combines with conventional ultrasound may contribute to the qualitative diagnosis of tumors in front of the orbit equator .
