Pheochromocytoma is a well known, catecholamine-producing tumor characterized by hypertension, headache, hyperglycemia, hypermetabolism, and hyperhydrosis. Approximately 65% of cases of pheochromocytoma were shown to be associated with hypertension. A case of pheochromocytoma that presented with thunderclap headache (TCH) and palpitations is reported. ⋯ According to the International Classification of Headache Disorders (ICHD)-II, headache attributed to pheochromocytoma usually develops concomitantly with an abrupt increase in blood pressure. In our case, however, hypertension was never observed, even when the patient was symptomatic. This is the first report of a case of pheochromocytoma with TCH without hypertension.

The objectives of this study were: (1) to assess relative frequency of migraine in multiple sclerosis (MS) patients using the validated self-administered diagnostic questionnaire, and to compare the migraine rates in MS outpatients to age- and gender-matched historical population controls; (2) to compare clinical and radiographic characteristics in MS patients with migraine and headache-free MS patients. We conducted a cross-sectional study to assess the demographic profiles, headache features and clinical characteristics of MS patients attending a MS clinic using a questionnaire based on the American Migraine Prevalence and Prevention (AMPP) study. We compared the relative frequency of migraine in MS clinic patients and AMPP cohort. ⋯ Migraine status was not significantly associated with disability on patient-derived disability steps scale or T2 lesion burden on brain MRI. Migraine is three-times more common in MS clinic patients than in general population. MS-migraine group was more symptomatic than the MS-no headache group.

We report a case of a woman presenting, 7 days after epidural analgesia for a caesarean section, to the emergency room for a worsening of the headache and tonico-clonic seizures. MRI showed alterations suggestive of the presence of intracranial hypotension (IH) as well as evidence of posterior reversible encephalopathy syndrome (PRES). ⋯ The possible pathogenetic relationship between IH, secondary to the inadvertent dural puncture, and PRES is discussed. We suggest that venous stagnation and hydrostatic edema, secondary to intracranial hypotension, probably played a crucial role in the pathogenesis of PRES.

There is a growing body of evidence implicating inflammatory cytokines and brain-derived neurotropic factor (BDNF) in the generation of migraine pain. No previous study evaluated BNDF levels during migraine attacks and there are conflicting results regarding tumor necrosis factor-alpha (TNF-alpha) serum levels. This study compared serum levels of TNF-alpha, soluble TNF receptors 1 and 2 (sTNF-R1 and sTNF-R2), and BDNF during migraine attacks and in headache-free periods. ⋯ BDNF serum levels were significantly higher during migraine attack than in pain-free period. This is the first report showing that BDNF serum levels increase during migraine attack. This reinforces the view that BDNF may be implicated in the physiopathology of migraine.
