[Tumours in the pineal region in the paediatric age. Reports of 23 cases and a review of the literature].

Introduction: Tumours in the pineal region are located at a meeting point of several neurovascular structures that are difficult to reach surgically and for which the possibility of resection is limited; as a result the management of these lesions usually requires associated adjunctive treatment with radiotherapy and/or chemotherapy.

Patients And Methods: This study is a retrospective analysis of the epidemiological, clinical, neuroimaging and pathological characteristics of 23 patients with tumours in the pineal region who were treated between the years 1997 and 2010 in the Hospital Infantil Niño Jesús. The factors involved in the prognosis of this cohort following surgical or adjunctive treatment are also discussed.

[Lumboperitoneal shunt in an outpatient setting for the treatment of chronic hydrocephalus in adults. A study and follow-up of 30 cases].

Introduction And Aims: One of the therapeutic options for chronic adult hydrocephalus that has become widely used in our service is the lumboperitoneal shunt with low-pressure Spetzler catheter and in an outpatient regimen. We report on the first 30 patients treated in this way with a follow-up of between one and five years.

Patients And Methods: Diagnosis was reached after studying the patient history and a clinical examination; Hakim and Adams' triad was found to be a primary and highly predictive factor, together with flow magnetic resonance imaging and the use of the ambulatory tap test.

[Tension pneumocephalus in a patient with a scalp wound and ventriculo-peritoneal shunt: case report and literature review].

Skull defects and even meningeal defects are responsible for the majority of pneumocephalus cases. Sometimes, several factors can produce intracranial gas under pressure (tension pneumocephalus) with severe neurological impairment. We present a case of a 66 year old woman with a double ventriculo-peritoneal shunt that was admitted to the emergency service with an intracranial hypertension syndrome.
