Reversible posterior leukoencephalopathy syndrome (rpls) is a clinical radiographic syndrome of heterogeneous etiologies that are grouped together because of similar findings on neuroimaging studies. Symptoms can continue for months to years and can vary from child to child. Tumors that occur in the cerebellar hemisphere, such as metastases, cerebellar astrocytomas, or cystic hemangioblastomas, may present by ataxia of the contralateral limbs.
