| Popis: | Bobble-head doll syndrome (BHDS) presents in childhood and is usually associated with lesions of the third ventricle. This disorder is characterized by stereotypical head movements of the type "yes-yes" (up and down) at a frequency of 2 to 3 Hz. Rarely, movements of the type "no-no" (side-to-side) are described. There are a few hypotheses to explain the mechanism responsible for BHDS, but its real pathophysiological characteristics are still unknown. The authors describe the case of a child born with hydrocephalus and Dandy-Walker syndrome. A ventriculoperitoneal shunt was implanted in the child because of progressive head enlargement. One year after shunt placement, she began making frequent horizontal head movements of the type "no-no". There were no other signs or symptoms. Imaging studies demonstrated small ventricles and a posterior fossa cyst with no signs of hypertension. The child's growth, development, and head circumference (within the 5th percentile) remained satisfactory. Three aspects of this case were of interest: the association of BHDS with Dandy-Walker syndrome, the rare occurrence of BHDS of the "no-no" type, and the absence of third ventricle dilation. The authors' findings support the hypothesis that cerebellar malformations themselves can |
