A case is presented on a 51 year-old man with stage IV oesophageal adenocarcinoma. The patient was referred by the Oncology Department urgently for a same-day assessment by an ophthalmologist due to two weeks of severe unilateral exophthalmos and binocular diplopia. A comprehensive eye exam revealed the presence of an axial non-reductive exophthalmos and a limitation in left eye levoduction. A computed tomography scan was performed that showed a multiple lobed, intra-and extra-conal, heterogeneous left orbital mass, that surrounded the internal rectus muscle, compatible with metastasis, as well as another small extraconal mass at the base of the contralateral orbit. Palliative radiotherapy was then indicated. Metastases in the extraocular muscles are a very rare finding, but should be suspected in a case of unilateral exophthalmos and, if necessary, refer the patient to have the corresponding complementary tests performed.
