MAIN OUTCOME MEASURES: Presenting clinical characteristics, radiographic findings, and histopathological features were assessed and correlated to discover distinctive presenting patterns. Volumetric measurements of the tumors and orbital soft tissue structures were made on magnetic resonance imaging studies. RESULTS: The breast metastases included 9 orbital and 1 eyelid lesions. Two distinct clinical presentations were observed. The first consisted of seven patients who had either enophthalmos or euphthalmos in the setting of a retrobulbar lesion, a radiographically indistinct lesion, and a classic microscopic invasive lobular breast carcinoma (ILBC) with a prominent fibrotic stroma. The second group consisted of two proptotic patients with mass lesions on imaging and an atypical ILBC pathological subtype (pleomorphic or alveolar). One patient had diffusely indurated eyelid fullness. Volumetric analyses demonstrated variable tumor sizes with an inconsistent impact on the orbital volume and fat. CONCLUSIONS AND RELEVANCE: This correlative study provides the clinical-radiographic-histopathologic basis for separating two overarching phenotypic presentations of metastatic breast carcinoma to the orbit. Previously postulated mechanisms for the distinctive finding of tumor-induced enophthalmos are re-examined in the light of the foregoing conclusions.},
