Supratentorial leptomeningeal metastasis of a medulloblastoma without cerebellar tumor recurrence.

The authors report on a 15-year-old girl presenting with headache and nausea. Cranial magnetic resonance imaging (MRI) showed a diffuse leptomeningeal contrast enhancement 5 years after resection of a posterior fossa medulloblastoma followed by radio- and chemotherapy. A left frontal biopsy revealed tumor spread.

[Cervical myelopathy in mucopolysaccharidosis type II (Hunter's syndrome). Neuroradiologic, clinical and histopathologic findings].

A moderately severe spasticity affecting all four limbs, but especially the legs and the right side, developed in a 36-year-old man with mucopolysaccharidosis II (Hunter syndrome) who for 6 months had suffered from pain in the neck radiating into the shoulder. Myelography, computed tomography and magnetic resonance imaging revealed thickening of the cervical meninges as the cause of the symptoms. A laminectomy was performed and the foramen magnum enlarged by an occipital craniotomy.

[Operation results in 2000 cases of lumbar intervertebral disk lesions (author's transl)].

Operative treatment of lesions of the lumbar intervertebral disks with compression of the nerve roots is directed against the principal biomechanical cause of the clinical picture of the lumbosciatica. Very satisfactory results can be obtained if, besides the removal of the prolapsed portions of the disk in the intervertebral space, the diseased layer is also carefully cleared out as far as it is possible to do so, in the interests of preventing relapse. The operation should not be considered one for the inexperienced surgeon.
