A case of an intradiploic leptomeningeal cyst of the posterior fossa in a 7-year-old boy is reported. Plain skull films demonstrated characteristic findings. The cause of the lesion was attributed to a head injury at 2 years of age. The pathogenesis and pathomechanism are discussed in contrast with supratentorial leptomeningeal cysts.
