[Abdominal migraine simulating acute abdomen].

Migraine is a variant of headache often associated with neurologic and/or vegetative symptoms mainly represented by abdominal pain. This symptom may occur some hours before migraine manifestation and in these cases the differential diagnosis with other clinical conditions characterized by abdominal pain, which is very common during childhood, may be difficult. Abdominal migraine can be diagnosed only if a close relationship is demonstrated between the abdominal symptoms and migraine. Alteration of consciousness is a well known feature during migraine and in some cases EEG may show SNC involvement during the attack. We report a case of abdominal migraine attack evaluated by EEG. The patient, a 10 years old male, presented with a picture of acute abdomen. An EEG performed at the occurrence of the early headache symptoms and of consciousness alteration demonstrated a pattern characterized by a lowering in the electric activity on the left hemisphere. Some hours later he developed a clear migraine followed by disappearance of the abdominal symptoms. This observation confirms the possible association of migraine with a picture simulating an acute abdomen and suggests that the differential diagnosis with a true surgical condition may be achieved by the observation of the progression of symptoms and by early evaluation of patient with EEG.
