Ophthalmoplegic migraine (OM) is a childhood disorder of uncertain etiology manifesting recurrent unilateral headache associated with a transitory oculomotor (usually IIIrd nerve) palsy. Recent publications emphasize the finding on MRI of contrast enhancement in the IIIrd nerve suggesting that OM may be a recurrent inflammatory neuropathy. We report the case of a 7-year-old boy with typical symptoms of this disorder. Angio MR and Angio CT revealed the presence of an infundibular dilatation of a perforating branch of the posterior cerebral artery adjacent to the symptomatic IIIrd nerve. We speculate that this and perhaps other cases of OM may have a different pathophysiology related to compression of the IIIrd nerve by an adjacent vascular structure that could activate the trigeminovascular system and produce migrainous pain.

Short-lasting headaches have been studied infrequently in children and it is not known if the main categories of primary headaches of this type in adults are applicable to children. We report our experience with a group of 20 children with a brief headache. Two patients had a secondary headache. One patient had a headache with some clinical characteristics of paroxysmal hemicrania. The remaining 17 had a very brief headache. They were in many aspects comparable to others from previous studies on idiopathic stabbing headache in children: no associated symptoms, no other associated headache, frequent family history of migraine. They differed, however, in the younger age of the patients and themore frequent extratrigeminal location of the pain. Extratrigeminal ice-pick pain may be a variant of idiopathic stabbing headache, more prevalent in young children.
