The cluster headache (CH) is one of the most severe types of head pain. It is a typical example of a periodic disease and the International Headache Society classification recognizes two forms of this disease: episodic and chronic CH. Its prevalence is about 0.1 to 0.4% in the general population. ⋯ Contraindications and side-effects of the drugs limit the choice of the prophylactic treatment: corticosteroids in a tapering course, verapamil and methysergide are the most useful treatments of the episodic form. Lithium carbonate is more effective for the chronic stage of CH, but side-effects are often troublesome. Numerous other medications have been used for prophylaxis: valproate, capsaicin, beta-blockers. Unfortunately, double-blind studies are often lacking and are difficult to realize due to spontaneous variable remission of episodic CH. When adequate trials of drug therapies show a total resistance to the treatments, surgery may be considered. Radiofrequency trigeminal rhizotomy is the treatment of choice with 70% of beneficial effects. Risks and complications have to be discussed in balance with the benefit of the different surgical procedures.

Henoch-Schonlein purpura is a rare eventuality in adulthood. Abdominal involvement can worsen the short-term prognosis and justify medical treatment to avoid surgery. ⋯ Abdominopelvic CT scan demonstrated signs suggestive of intestinal vasculitis. An underlying neoplasia or an eventual other cause of abdominal pain were explored and a steroid therapy was then began with a good outcome. Abdominal CT can be helpful in the diagnosis of abdominal involvement in Henoch-Schonlein purpura.
