An Aneurysmal Bone Cyst (ABC) is a benign, locally aggressive, vascular, and expansile bony tumor of idiopathic etiology containing multiple thin-walled blood-filled channels, mostly diagnosed in pediatric and adolescent age groups. These lesions can cause local pain, pathological fractures, spinal deformity, and neurological deficits. The treatment of choice for ABC is highly debatable according to the literature. The treatment choices are simple curettage and grafting, complete surgical resection with or without prior selective arterial embolization, radiotherapy, or a combination of these procedures according to the case. Each modality is having different outcomes, technical requirements, and complications. We are reporting a case of Aneurysmal Bone Cyst of the lumbar spine in a young patient treated by surgery.

It is relatively common to occur in a Tertiary Care Neurosurgical setup to get a case of Syringomyelia proximal or distal to a space-occupying lesion (SOL) or site of spinal cord compression. In this case series, we are presenting two cases in which syringomyelia developed after traumatic spinal cord injury. On initial radiological investigations, the first case presented as an old D12 fracture with Post-traumatic syrinx formation but on complete workup for the extent of the syrinx, another lesion was found incidentally in the form of an intradural extramedullary SOL at the level of cervicomedullary junction. The SOL turned out histologically as WHO Grade I Meningioma. The second case presented as syrinx formation after gunshot (fire-arm) penetrating spinal cord injury to the D11-12 vertebrae. Treatment plans of both these patients are presented here in detail along with the literature review.
