Oculomotor nerve tumors masquerading as recurrent painful ophthalmoplegic neuropathy: report of two cases and review of the literature.
In recurrent painful ophthalmoplegic neuropathy (RPON) that was previously termed as ophthalmoplegic migraine, enhancement of the ocular motor cranial nerves could be seen in the cisternal segment during the acute phase. However, various tumors involving the oculomotor nerve may mimic RPON. ⋯ It should be recognized that an incomplete recovery may occur during future attacks in patients with otherwise uncomplicated RPON. Follow-up MRIs are required to detect tumors involving the ocular motor cranial nerves, especially in patients with suspected RPON when the recovery is incomplete.
