Orbital metastatic tumor

Orbital metastatic carcinoma represents an important group of orbital occupying lesions. The diagnosis often indicates poor prognosis for patients, so it requires accurate diagnosis and decisive and effective management. There is a fairly clear difference between metastatic cancers in adults and children: in adults, most metastatic cancers are cancers that come from the epithelial structures of the breast, lung, bladder, gastrointestinal tract, kidney, thyroid, and other organs; Metastatic cancers are mostly embryonic neuronal tumors and sarcomas. Therefore, childhood neuroblastoma, Ewing sarcoma, and Wilms tumor are more important diagnostic considerations. The primary location of orbital metastatic tumors is relatively wide, and malignant tumors in almost all parts have the possibility of metastasis to the orbit. Ocular symptoms and signs often appear first in organs deep in the primary site. It is not uncommon to see ophthalmologists for lung and liver cancer. For middle-aged and elderly eye malignant tumors, a detailed systemic examination should be carried out, especially imaging examinations of the respiratory, digestive and urogenital systems are often necessary to exclude metastatic tumors. Most metastatic tumors directly invade the lacrimal glands, extraocular muscles, and optic nerves, making it difficult to make a differential diagnosis.
