Case ReportsSyndrome of overdrainage associated with disconnection of a ventriculoperitoneal shunt.
We present the case of a child who developed the syndrome of cerebrospinal fluid (CSF) overdrainage with slit-like ventricles on CT in the setting of a disconnected distal shunt valve. Upgrading the shunt alleviated his symptoms. It is suggested that the presence of a patent fibrous tract allowed the overdrainage of CSF.

Posterior fossa syndrome: identifiable risk factors and irreversible complications.
Cerebellar mutism was first described by Rekate et al. in 1985 as a transient condition which occurs after posterior fossa operations in children. Posterior fossa syndrome (PFS) and cerebellar mutism are often used interchangeably in the literature. In our experience, we found cerebellar mutism to be a reversible component of a persistent neurologic syndrome. ⋯ Although mutism resolved in all cases, the remaining neurologic complications which characterized our findings of PFS were rarely reversible. We describe potential risk factors for developing PFS after surgery with hopes of making neurosurgeons more aware of potential problems following the removal of lesions in this area. Early recognition of PFS would further promote patient and family understanding and coping with this syndrome.
