Venous angioma associated with atypical ophthalmoplegic migraine.

Background.—Ophthalmoplegic migraine is a rare syndrome in which episodic headaches are associated with ophthalmoplegia. Several recent reports emphasize the possibility, especially in atypical cases, of a heterogeneous type of ophthalmoplegic migraine. Methods.—We describe the case of an 18-year-old woman with recurrent episodic headache accompanied by binocular diplopia due to left third cranial nerve palsy. The symptoms resolve in hours. A diagnosis of atypical ophthalmoplegic migraine was established. Results.—Digital angiography revealed a venous angioma draining into the left cavernous sinus. Conclusions.—This case reveals the importance of differential diagnosis in atypical migraine in which the symptomatology could be secondary to intracranial lesions. We propose venous stasis as a cause of symptoms.
