RESUMO
BACKGROUND: Orbital metastasis of breast cancer is an unusual condition, especially in the absence of a previous diagnosis of primary breast cancer. The main MRI findings in patients with orbital metastasis are retroorbital soft tissue with thickening of extraocular muscles. Paradoxical enophthalmos secondary to fibrosis can be seen. CASE REPORT: In this case report, we present a 75-year-old female patient with left eye pain and blurred vision and retraction. Although there was no evidence of malignancy in the biopsy of the orbita; since the patient's complaints continued despite idiopathic pseudotumor treatment, mammography was recommended to rule out the possibility of breast cancer metastasis. Her mammography revealed a suspicious lesion in the left breast and proved to be pleomorphic invasive lobular cancer. CONCLUSION: Breast cancer metastasis should be kept in mind in women with pseudotumor -like the involvement of the orbita.
