BackgroundBelly dancer’s dyskinesia is an extremely rare condition. It manifests as semicontinuous, slow, writhing, sinuous abdominal wall movements that are bothersome to the patient. Management of this condition is extremely difficult and challenging.MethodsWe describe four patients with belly dancer’s dyskinesia who were treated with Botulinum Toxin A (BTX) injections under ultrasound guidance.ResultsAll patients underwent the same BTX injection procedure using an aseptic technique under ultrasound guidance. The patients responded well to the BTX injections after an unsatisfactory course of medical treatment. The patients reported complete abolishment of abnormal abdominal movements with no side effects.ConclusionsWe report a cohort of patients with belly dancer dyskinesia treated successfully with BTX injections. Ultrasound guidance for injections increases the accuracy and reduces the risk of the complications. BTX injection under ultrasound guidance is a safe and effective treatment modality that should be employed as a first-line in the management of patients with belly dancer’s dyskinesia.Electronic supplementary materialThe online version of this article (doi:10.1186/s12883-016-0746-5) contains supplementary material, which is available to authorized users.

A 32 year old Asian female on 300 mg per day of phenytoin following meningioma excision developed a fever with a diffuse maculopapular rash, lymphadenopathy and splenomegaly after12 days. A diagnosis of DRESS (Drug Rash Eosinophilia and Systemic Symptoms) syndrome was made. Patient was started on prednisolone at a dose of 1 mg/kg but since there was further deterioration in her condition, intravenous immunoglobulin was started. Clinical and blood parameters began to improve by the next day with liver functions returning to normal by the third week. DRESS syndrome is a drug hypersensitivity syndrome which can be fatal and therefore needs to be recognized early for the appropriate treatment to be started. The use of Intravenous immunoglobulins is anecdotal and the dramatic improvement noted in this case indicates that it is another treatment choice. The case and a brief review of the literature are discussed.
