Dandy-Walker malformation and syringomyelia: a rare association

Case Report



Dandy-Walker malformation is a rare condition due to imperforation of the Blake’s pouch during intrauterine brain development, usually leading to early severe hydrocephalus. The association with holocord syringomyelia is rare, and from the Gardner’s first report in 1957, only 23 cases have been described, mostly from autopsy series and pre-MRI period. Besides a worsening of clinical picture, its occurrence generates some concern about the best surgical treatment that varies widely among the literature reports.


An 11-year-old girl with Dandy-Walker malformation presented with a holocord syrinx due to the herniation of the lower pole of the posterior fossa cyst through the foramen magnum.


After an unsuccessful shunt revision, she underwent a cystoperitoneal shunt with regression of the syrinx and of neurological symptoms at the 12-month follow-up.


Previous literature about pathogenesis, treatment, and follow-up is discussed and summarized.
