  • tumors of the Superior Medullary Velum in infancy and childhood report of 6 cases clinical article
    Journal of Neurosurgery, 2013
    Co-Authors: Tadanori Tomita, Paolo Frassanito
    Abstract:

    Object The Superior Medullary Velum (SMV) is a thin lamina of white matter located between the Superior cerebellar peduncles horizontally and between the midbrain and cerebellum vertically. The SMV has not previously been described as the primary location of a posterior fossa tumor, although it can be secondarily invaded by a tumor from the cerebellum or quadrigeminal plate. This paper aims to define clinical and radiological features of tumors primarily arising from the SMV during childhood. Methods The authors observed 6 infants and children harboring neoplasms of the SMV who were treated at Ann & Robert Lurie Children's Hospital of Chicago (formerly Children's Memorial Hospital) in Chicago, Illinois. Pathological diagnosis of the neoplasms was an atypical teratoid/rhabdoid tumor (ATRT) in 5 patients, and a juvenile pilocytic astrocytoma (JPA) in the remaining child. The tumors were diagnosed during infancy in all patients, with ages ranging from 3 months to 10 months, except for the patient with a JPA ...

  • Midline medulloblastoma versus astrocytoma: the position of the Superior Medullary Velum as a sign for diagnosis
    Child's Nervous System, 2008
    Co-Authors: G Trasimeni, Jacopo Lenzi, Claudio Di Biasi, Giulio Anichini, Maurizio Salvati, Antonino Raco
    Abstract:

    Purpose We wish to describe the position of the Superior Medullary Velum (SMV) in midline posterior fossa tumours as a sign in helping to distinguish between midline medulloblastoma and midline astrocytoma. Material and methods Sagittal T1-weighted MRI images of 21 consecutive patients with histologically documented posterior fossa midline astrocytomas (nine cases) and medulloblastomas (12 cases) were reviewed, with respect to the position of the Velum medullare superius. Results In all medulloblastomas the SMV was Superiorly dislocated; in eight astrocytomas it was anteriorly and/or inferiorly disclocated; only in one astrocytoma the SMV presented upward dislocation. Conclusion In the differential diagnosis between medulloblastoma and astrocytoma the upward dislocation of the SMV is strongly suggestive of medulloblastoma.
