Metastatic orbital tumour from gastric cancer is rare. Patients with metastatic disease may present initially to the ophthalmologist with symptoms from metastases instead of from the primary cancer.
We report a case, with clinicopathological correlation, of metastatic gastric adenocarcinoma presenting first in the orbit with diplopia. Computed tomography and magnetic resonance imaging of the orbit showed a well-defined enhancing right intraconal tumour.
TREATMENT AND RESULTS:
Excisional biopsy was performed and histopathology confirmed a metastatic adenocarcinoma. Focused gastrointestinal screening revealed an otherwise asymptomatic Stage IV gastric adenocarcinoma. Chemotherapy was initiated with good tumour response.
