Solitary Orbital Metastasis Presenting as Extraocular Muscle Mass in Lung Cancer Patient: A Case Report

A 74-year-old man presented with right ocular pain and diplopia. Contrast enhanced orbital computed tomography showed a bulging mass with homogenous density and mild homogeneous enhancement, at the right medial rectus muscle belly. Magnetic resonance imaging of the orbit showed a bulging mass along...

description A 74-year-old man presented with right ocular pain and diplopia. Contrast enhanced orbital computed tomography showed a bulging mass with homogenous density and mild homogeneous enhancement, at the right medial rectus muscle belly. Magnetic resonance imaging of the orbit showed a bulging mass along the medial rectus muscle, with superiorly displaced medial rectus muscle. The mass showed homogenous hyperintensity to extraocular muscle on T2-weighted images, and mild rim enhancement on contrast enhance T1-weighted images. Differential diagnosis of images included primary lesion of the extraocular muscle such as lymphoma, inflammatory pseudotumor and myositis. Chest X-ray incidentally revealed a left hilar mass. Histopathologic diagnosis of the hilar mass was confirmed as small cell lung cancer. A total body 18F-fluorodeoxy glucose positron emission tomography scan revealed abnormal uptake only in the left hilar region and the right orbit. Histopathologic diagnosis of the extraocular muscle mass was metastasis of the small cell lung cancer. Although there are few reports of small cell lung cancer with orbital metastasis, solitary extraocular muscle metastasis without other systemic metastasis is quite rare. Here, we report the case with an initial presentation of a solitary EOM metastasis, in a patient with small cell lung cancer.
