etastasis to the orbit, which is uncommon due to the haracter of the orbital volume with relative stenosis, is stimated to account for 1--13% of all orbital tumors.1 rbital metastasis is believed to occur in approximately --3% of patients with systemic cancer.2 The incidence f metastatic orbital tumors varies widely, according to eographical area and race; the most common primary caners that me...

We report a case of orbital metastasis in a previously diagnosed metastatic breast cancer in a 46-year old woman presenting with diplopia and proptosis of her left eye bulb. An orbital computed-tomography (CT) and a magnetic resonance imaging (MRI) both revealed an intra-orbital extra-bulbar mass of 1.5 × 3 cm in size, in the left orbit. The patient had been diagnosed with stage IV breast cance...

Two cases in which orbital metastasis produced enophthalmos, instead of the usual exophthalmos, are reported. Only fourteen other cases have been described previously and they are reviewed. At time of diagnosis of the enophthalmos, meningeal carcinomatosis coexisted in the first case and probably also in the second case. This association can lead to diagnostic errors with either the orbital met...

We present the case of a 33-year-old man with acute onset of eye pain and diplopia as the presenting symptoms of rectal cancer with orbital metastasis. Colorectal cancer with orbital metastasis is exceedingly rare with only 7 cases worldwide despite the prevalence of colorectal cancer. The rarity of this presentation may be related to the long path through multiple vascular beds that tumor embo...

Orbital metastasis as the initial presentation of lung adenocarcinoma is very rare, and so the lack of knowledge about this phenomenon can easily result in misdiagnosis, either as a orbital primary tumor or benign lesion. Here, we report a rare case in which the orbital symptom appeared first without any pulmonary manifestations. Our patient developed decreasing vision in his right eye over a 3...

Primary hepatocellular carcinoma is one of the most common cancers in Taiwan, but orbital metastases are rare. To the best of our knowledge, only 10 cases of metastases to the orbit have been described in the literature. This may be related to the short clinical course of the malignancy and the fact that most patients died before metastasis occurred. We describe a 69-year-old man who developed ...

Orbital metastasis from lung cancer as an initial presenting symptom is a rare entity, which may paradoxically delay the diagnosis and initiation of correct management, due to the confusion of it being primary orbital pathology. Herein we report a case of a 58 year old woman, who presented with painful orbital swelling along with diminution in her vision. The patient was initially thought to ha...
