As a consequence of the continued armed confl ict in Colombia, which might as well be called a low intensity war, the Armed Forces personnel, suffer with relative frequency penetrating wounds from fi rearms, who in the majority are transferred to the Hospital Militar Central in Bogota, with an average of 350 patients in the multiple services. The majority of the cases are due to wounds from high speed fi rearms, which cause signifi cant tissue damage from the liberated energy, as well as from fragmentation weapons, in which there are a multiplicity of lesions seen. This review is limited to those cases localized within the central nervous system. In continuity with the fi rst part, this second part goes into details of the phisiopathology of these types of wounds in the central nervous system and we show some extraordinary cases, emphasizing to the reader the basic knowledge necessary for the management of these patients.
