RESUMO
Syringomyelia is condition in which a cyst or cavity forms inside the spinal cavity. Its management always remains a difficult. A variety of surgical techniques have been used in management of syringomyelia. Syringosubarachnoid shunt remains an effective method in management of syringomyelia. Shunt tube obstruction remains an important complication of shunt procedure. We describe a novel technique of use of polytetrafluoroethylene sponge shunt for syringosubarachnoid shunt in patient with large syrinx and Chiari 1 malformation. Polytetrafluoroethylene sponge is a non irritant material with multiple porosities that is less susceptible to blockages or kinking. It could provide a good alternative technique in syringosubarachnoid shunting.

A mucocele is a collection of mucus, which is lined by the mucus-secreting epithelium of a paranasal sinus. Paranasal sinus mucoceles occur as a result of inflammation, tumor, trauma or surgical manipulation. The anterior clinoid process may be pneumatized by an extension of the sphenoid paranasal sinus air space during normal development. Mucocele of the anterior clinoid process is rare. We report a patient with mucopyocele of the anterior clinoid process that resulted in rapid monocular visual loss. The left optic canal was exposed extradurally via a supraorbital craniotomy and the mucopyocele was totally excised. The optic canal was decompressed by drilling the superior, lateral and medial rims, to achieve circumferential decompression of the optic nerve. The patient's vision improved postoperatively.

We present a large cervicomedullary intramedullary lipoma in a 17-year-old boy, who presented with spastic quadriparesis and exaggerated reflexes. MRI revealed an intramedullary lipoma extending from the craniovertebral junction to the sixth cervical vertebra. There was no spinal dysraphism. Subtotal excision with primary dural closure was performed, which produced an improvement in the patient's condition. The technique we used is discussed.
