Traumatic spinal cord injuries(SCI) are characterized by damage in the integrity of the spinal cord,which results in either temporary or permanent alterations in the locomotor,sensory and/or autonomic functions(Yezierski,2009).The traumatic event leads to impairments in voluntary control of movement below the injury by affecting the connection between the brain and the neurons localized in the spinal cord.

Traumatic spinal cord injuries interrupt the connection of all axonal projections with their neuronal targets below and above the lesion site. This interruption results in either temporary or permanent alterations in the locomotor, sensory, and autonomic functions. damage in the spinal tissue prevents the re-growth of severed axons across the lesion and their reconnection with neuronal targets. Therefore, the absence of spontaneous repair leads to sustained impairment in voluntary control of movement below the injury. For decades, axonal regeneration and reconnection have been considered the opitome of spinal cord injury repair with the goal being the repair of the damaged long motor and sensory tracts in a complex process that involves:(1) resealing injured axons;(2) reconstructing the cytoskeletal structure inside axons;(3) re-establishing healthy growth cones;and(4) assembling axonal cargos. These biological processes require an efficient production of adenosine triphosphate, which is affected by mitochondrial dysfunction after spinal cord injury. From a pathological standpoint, during the secondary stage of spinal cord injury, mitochondrial homeostasis is disrupted, mainly in the distal segments of severed axons. This result in a reduction of adenosine triphosphate levels and subsequent inactivation of adenosine triphosphate-dependent ion pumps required for the regulation of ion concentrations and reuptake of neurotransmitters, such as glutamate. The consequences are calcium overload, reactive oxygen species formation, and excitotoxicity. These events are intimately related to the activation of necrotic and apoptotic cell death programs, and further exacerbate the secondary stage of the injury, being a hallmark of spinal cord injury. This is why restoring mitochondrial function during the early stage of secondary injury could represent a potentially effective therapeutic intervention to overcome the motor and sensory failure produced by spinal cord injury.

An angiosarcomatous component in gliosarcoma may be associated with an increased intraoperative hemorrhagic risk and preoperative diagnostic challenge. We report a unique case of gliosarcoma with an angiosarcomatous component in a 61-year-old man. His brain MRI demonstrated a well-demarcated right occipital tumor with multiple flow voids and rim-like enhancement as well as intratumoral strip and nodular enhancements. He underwent a craniotomy for tumor resection. Intraoperatively, significant tumor hemorrhage required greater efforts to control intraoperative bleeding and to maintain hemostasis. Pathological examination of the tumor revealed alternating gliomatous and sarcomatous/angiosarcomatous components with intratumoral hemorrhage. He was postoperatively treated with chemoradiation. The tumor recurred at 9 months, for which the second resection was performed with similarly greater efforts to achieve hemostasis. The recurrent tumor was pathologically similar despite treatment-associated changes. Awareness of this angiosarcomatous component in gliosarcoma with the hemorrhagic risk is important for both the preoperative diagnosis and surgical management.
