RESUMO
Symptomatic glial cyst of the pineal gland are rare lesions. Origin, natural history and factors leading to cyst enlargement are not completely clear; thus management remain uncertain in some cases. We report a case of symptomatic glial cyst and analyze the implication for surgery. Surgical management is indicated in patients presenting hydrocephalus, mass effect or symptoms related to mesencephalic dysfunction. The infratentorial supracerebellar approach represent the first choice for this condition allowing easy orientation with wide exposure of the tumor and good visibility of deep venous systems that may be preserved. Size of the tumor is a key element in evaluation of the treatment and the appropriate course for asymptomatic cyst less than 1 cm in size consist of conservative management. Periodic follow up is always indicated.

Nonneurogenic dumbbell tumors are rare. This report describes the case of a 46-year-old woman with a symptomatic mediastinal dumbbell angiolipoma. The tumor was successfully resected using a single-stage procedure, combining a posterior microneurosurgical and thoracoscopic approach. The patient made an uneventful recovery and the neurologic symptoms improved immediately.

A case of spinal ependymoma diagnosed 26 years after the removal of an acoustic neurinoma in a patient free of von Recklinghausen's disease is described. The extreme rarity of such a finding and the pathogenetic hypotheses regarding multiple primary tumors of the nervous system are discussed at the light of the literature.

A case of meningioma developing between two sheets of the spinal dura mater is reported. The genesis of this neoplasm, arising from arachnoidal villi included into the dura is discussed. The authors suggest to distinguish the term 'intradural' from 'subdural'.
