Fragile X syndrome is the most common cause of inherited intellectual impairment and
has been associated with decreased incidence of cancer. We present the case of an
11-year-old boy with a diagnosis of fragile X syndrome who presented with gait imbalance,
headache, and episodes of vomiting. Radiological investigation revealed the presence
of a posterior fossa tumor. The patient was operated upon and the tumor proved to
be a medulloblastoma (MB). To the best of our knowledge this is the first reported
case of MB in a child with fragile X syndrome.
