1 Headache Unit, University Hospital of Valladolid, Valladolid, Spain.
Background: Epicrania fugax is included in the appendix of the International Classification of Headache Disorders and is characterized as recurrent brief attacks of linear or zigzag pain moving across the cranial surface, commencing and terminating in the distribution of different nerves. We present a new case of epicrania fugax in which the headache was the presenting symptom of a cerebellar abscess.
Case Report: We present a 58-year-old woman with prior history of Chiari I malformation who underwent suboccipital craniectomy. Two weeks after surgery, she experienced paroxysmal pain episodes of 1-3 seconds, with constant linear trajectory from the right occipital surface to the right orbital region, remaining pain free between episodes. Cranial tomography showed a hypodense intraaxial lesion in the right cerebellar hemisphere. Magnetic Resonance Imaging exhibited intralesional bleeding and peripheral enhancement after gadolinium administration. Post-surgical cerebellar abscess was diagnosed and antibiotic therapy was started; the patient underwent urgent surgical drainage. Pain disappeared after the surgery and the patient remains pain free with 12 months of follow-up.
Conclusion: Posterior fossa abnormalities have been described as a possible cause of secondary epicrania fugax. The presence of red flags should encourage conducting of paraclinical tests to rule out a symptomatic form.
