RESUMO
A 10-year old boy who had undergone a ventriculoperitoneal (V/P) shunt because of hydrocephalus at 10 days of age was doing well until 20 days ago, when he began to experience headache and seizures. CT scan revealed dilated lateral ventricles and calcification at the shunt site. X-rays showed an unusual calcification pattern around the shunt tube and rupture of the tube between the mastoid bone and clavicle. The patient underwent surgery and the shunt was changed completely. The ventricles became small in the follow-up. Even though V/P shunts may induce fibrous tissue formation and calcification around the tube, there are a few cases of shunt rupture and calcification of shunts in the literature. Possible mechanisms of the rupture and calcification are discussed in this paper.

Extracranial metastasis of a malignant glioma is rare, possibly due to the lack of lymphatic drainage in the brain and because these tumors are unable to penetrate blood vessels. Extracranial metastasis of an anaplastic oligodendroglioma (ODG) is exceptionally rare. We present a 55-year-old male patient with diffuse extracranial metastases from a temporal anaplastic ODG, 11 months after cranial surgery. Anaplastic ODG, may spread to the other parts of the body. If patients with these tumors have neck or back pain, spinal metastasis should be included in the differential diagnosis and further investigated.
