Focal leptomeningeal rhabdomyomatosis of the posterior fossa.
We describe two infants with heterotopic skeletal muscle in the leptomeninges of the posterior fossa. In one case, the heterotopic muscle was accompanied by adipose tissue. Leptomeningeal rhabdomyomatosis may be more common than is apparent from the literature, since these lesions are missed if the meninges become denuded from the brain stem at autopsy or brain cutting.
