The authors study 51 patients with subarachnoid hemorrhage due to suspected intracranial aneurysms who underwent surgery in the Daniel A. Carrión Hospital, Peru, from May 2004 to Nov 2007, to determine the validity, sensitivity and specificity of 16 multislice spiral CT angiography (ATEM) in the diagnosis of cerebral aneurysms. They concluded that CT angiography is an excellent noninvasive test for the detection of intracranial aneurysms and to determinen their location.    

Magnetic resonance spectroscopy allows a more accurate diagnosis of intraparenchymal brain lesions of uncertain etiology and occurs when the lesion is unique, brain neoplasia and tuberculomas, enabling better-targeted treatment for patients. The authors carried out a study in 24 patients aged between 02 and 72 years who underwent the brain structural and spectroscopic study univoxel with voxel of 20 mm x 20 mm x 20 mm (8 cc) located at the level of the lesion determined.

The authors present the case of a 32 year old patient with spinal cord compression syndrome of 10 months of evolution. Magnetic resonance imaging showed signal voids causing myelopathy that spinal angiography showed to be a type IVb spinal arteriovenous malformation (perimedular arteriovenous fistula type II) supplemented by a posterior spinal artery that originated next to the Adamkiewicz artery from the segmental artery T11 left.

Neurosurgery is successively founder Mauricio Dávila in 1944 at the Police Hospital, Esteban Roca in 1947 in the Obrero Hospital, Fernando Cabieses at the Institute of Neoplastic Diseases and Juan Franco the the Institute of Neurological Sciences . After these services have made many more, led by prominent and prestigious Neurosurgeons meeting in what today is the Peruvian Society of Neurosurgery.
