Highlights Endolymphatic Sac tumors are very rare type of tumor reported in practice of Neurosurgery or ENT. This tumor may present in sporadic fashion or as a part of Von Hippel Lindau disease. In this case report Endolymphatic Sac Tumor of sporadic type is presented at the cerebellopontine angle in the posterior fossa of the skull. It was managed in our facility with multidisciplinary approach. The clinical presentation, investigations and management of the patient are discussed in details and a brief review of the literature has been performed.

HighlightsHydatid cyst represents the parasitic infection by Genus Echenococcus Granulosis. The disease involves mainly Liver followed by lungs and rare involvement is seen in CNS.When it is found in Brain it is usually present in supratentorial compartment rather than infratentorial compartment. The usual area is intracerebral hemisphere. They can be isolated cyst or multicystic. Involvement of Infratentorial compartment of CNS is extremely rare.In this case report we are presenting a rare case of Multiple Hydatid cysts involving the peripontomedullary area and extending all the way down to the foramen magnum.

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.
