Infectious diseases and infestations are due to the local aggression of the central nervous system and its envelopes, by microbial or parasitic agents, capable of causing damage to our health, causing local and general symptoms.

Endonasal endoscopic surgery is a team surgery according to Snyderman et al., which requires learning of non-familiar surgical anatomy, use of new technologies and the development of new surgical skills. The major concerns during surgery are the identification of the internal carotid artery, optic nerves and preservation of small cerebral vessels. The potential for a disaster is great if the surgeon is unfamiliar with the anatomy, there is a lack of adequate equipment and clumsiness to maintain adequate visibility with the endoscope. Many publications speak on the subject, both on transsphenoidal endoscopic anatomy, and on anatomy with the approach by extending its limits.

Cysticercosis is the most common parasitic infection affecting the central nervous system and typically involves the cerebral parenchyma, the subarachnoid space, or the ventricular system. Spinal cysticercosis is rare (0.7-3.2%) even in endemic regions and may require more aggressive management due to the natural confines of the spinal canal. The condition of the lesion, its size, and the inflammatory response generated by cyst degeneration are important factors for the management of spinal CC. We report two cases of spinal cysticercosis in which patients underwent surgical treatment.

With the advances in the medicine, we have a high average of life and at the present time leave increment of patient with spine pain for pathological fractures taken place by osteoporosis or in other conditions such as: Spinal metastases, multiple myeloma lesions, and hemangiomas. It is necessary the vertebral stabilization in these patients to improve the pain and at the moment with technical Percutaneous Spinal Vertebroplasty can be reinforced and to give bigger 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, is injected into the bone in the vertebral fractured body, through a stem.Sometimes at level of the spinal compression fractures, we can to introduce and inflates a small balloon into the vertebra to expand its height before injecting the PMMA. This technique is known as Kyphoplasty or Vertebroplasty mediating balloon. The indications of the Vertebroplasty and Kyphoplasty at the moment are the reinforcement of vertebral fractures for spinal metastases too.
In this paper we review the technical basis of the vertebroplasty, according to our experience in this treatment and we present our experience with a small number of cases which had a good outcome for the majority of them.

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, 4) Recurrent metastases. The relative indications for radiosurgery alone, radiosurgery, more radiotherapy, radiotherapy alone and surgical resection remain controversial. Because of its proven efficacy and low morbidity, radiosurgery could be indicated for most cases of brain metastases excluding lesions larger than 3.5 cm, numerous metastases (depending on cumulative volume and whole dose to the brain) and / or with symptomatic mass effect, or causing hydrocephalus. In the latter case the surgery would be the first therapeutic consideration and when a biopsy is necessary to confirm a neoplasia.

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.
