The authors present a retrospective and descriptive study of 34 patients, 25 men and 9 women 9; mean age 33.23 years, with diagnosis of thoracolumbar vertebral fracture treated surgically with instrumentation (transpedicular fixation or anterior plaque) in the Department of Neurosurgery of Guillermo AlmenaraHospital in Peru between Jan 1996 and Dec 2002. The average follow-up was 23 months (from 8 to 36 months) and all had neurological deficit: total(14) and partial(20).

Percutaneous Spinal Vertebroplasty give more consistency or hardness to the fractured spine.The technique consists to guide placement of the needle and the plastic bone cement that is injected into the vertebrae to stabilize them using Poly methyl methacrylate (PMMA), which is radiopaque due to sterile barium powder, it is injected into the bone in the vertebral fractured body through a stem.

In cerebral vascular pathology in children, arteriovenous malformations (AVMs) are the most frequent and they are being detected now more and more even at the asymptomatic stage. On the other hand, we know that the surgery was the mainstay of their treatment; However in the last decades the endovascular techniques and radiosurgery have evolved, and currently for the treatment of AVMs, several options are considered as unique or adjuvant according to guidelines established in various hospitals.

Radiosurgery may be chosen for brain metastases smaller than 3.5 cm. Of large diameter and with the primary tumor controlled in the following scenarios: 1) Solitary metastases and in good neurological conditions could be treated with radiosurgery only 2) Relatively radioresistant metastases such as melanoma and renal cell carcinoma, 3) Multiple metastases, complementing with total brain radiotherapy,and 4) Recurrent metastases.

Transcranial Doppler (TCD) is a useful tool in the diagnosis of both regional and diffuse vasospasm, as it is demonstrated in this case (corroborated by angiography). This makes it possible not to reduce triple therapy H when the patient still requires it, TCD is a important arsenal we have, it is not enough clinical diagnosis, since the TCD is noninvasive, fast, online, is performed in bed Patient, and the Doppler vasospasm occurs before clinical vaospasm which makes it a very useful tool

The pituitary carcinomas are rare and aggressive adenohypophyseal tumors, that usually present themselves like invasive macroadenomas, producing ACTH or prolactin. For clinical definition, they have metastases of a pituitary neoplasm, craniospinal or systemic. It is possible the existence of a time of latency between the diagnosis of pituitary tumor and the diagnosis of pituitary carcinoma that may vary from 5 to 12 years.

Ependymomas in the pediatric population should be considered high risk if the patient is younger than 3 years of age at the time of diagnosis, if he has preoperative metastases, features of anaplasia, or residual tumor, surgery as a therapeutic modality is the one that Provides greater disease-free survival, adjuvant therapy does not determine predictive value.

When we read or hear Normal Pressure Hydrocephalus or chronic hydrocephalus of the adult as it is called at the moment, the Hakim Adams Syndrome comes to our mind immediately. We find it very important to expose the history of the discovery of hydrocephalus at normal pressure,
Pathology that to date has many questions and is a subject of constant research.
