Prognostic limitations of the Daumas-Duport grading scheme in infratentorial neuroglial tumors in children.

The Daumas-Duport grading scheme (DDGS) utilizes four histologic features in an additive method (grade 1 if none present, grade 2 if only one is present, etc.). Its efficacy in achieving prognostically homogeneous groups of childhood infratentorial neuroglial tumors and its concordance with World Health Organization (WHO) diagnoses has not been evaluated.

A rare case of lymphangiomatosis of the craniocervical spine in conjunction with a Chiari I malformation.

Lymphangiomatosis of the bone is rare. The axial as well as appendicular skeleton may be affected. Neurosurgical consultation may be called for several reasons: (1) lesions involving the calvarium and/or spine; (2) nondiagnostic biopsies from more accessible and less morbid locations, and (3) persistent CSF leak and/or recurrent meningitis.

Castleman's disease in a child presenting with a partly mineralized solitary meningeal mass.

We report a case of solitary intracranial childhood Castleman's disease (CD) presenting with a sudden onset of partial seizures due to a meningeal and cortical mass lesion. The patient was a previously healthy 8-year-old girl who developed a new onset of simple partial seizures with motor signs. On physical examination, she was neurologically intact.

Absence of hippocampal sclerosis in children with multiple daily seizures since infancy.

We report a series of nine children with multiple daily seizures since infancy who underwent functional hemispherectomy that included en bloc resection of the hippocampus and the temporal neocortex. In all cases, the hippocampi were normal by conventional histology despite the fact that these patients had suffered from recurrent seizures over a long period of time. This observation suggests that extremely frequent seizures in childhood are not invariably associated with the development of hippocampal sclerosis.

Carpal tunnel syndrome due to an intraneural perineurioma in a 2-year-old child.

We report a 2-year-old girl with carpal tunnel syndrome due to a large intraneural perineurioma that required resection and nerve reconstruction.
