A 72-year-old man complaining of sudden-onset diplopia in the right eye presented to our Ophthalmology department. He provided a previous history of prostate cancer and was tumor-free for 10 years. The diplopia was binocular, worse in distance. The ocular movement of the right eye showed moderate limitation in the right gaze. The examination of all other cranial nerves was normal. The patient underwent neuroimaging with the diagnosis of isolated cranial nerve (CN) VI palsy which revealed abnormal bone marrow signal and expansion of clivus, sphenoid, and an orbital plate of frontal bone at the right orbital roof. The patient underwent a bone scan that confirmed generalized bone metastasis. Here we present the case of a 72-year-old man with isolated CN VI palsy as the only presenting sign of bone metastasis secondary to prostate cancer. Systemic cancer history is an important risk factor that should not be overlooked in patients with isolated CN VI palsy nerve palsy.
