Hydatid cyst is a common zoonosis, affecting the liver and lungs in the endemic areas. Occasionally it involves the brain. We present a rare case of multicystic cerebral Hydatid cyst present over a long time in an adult patient with some odd radiological features like calcification and discuss the relevant literature. In endemic areas, neurosurgeons must be aware of this entity.

Background Neuroblastoma can arise from extra-adrenal sites in the paraspinal sympathetic chain, including the presacral region, where they must be differentiated from an immature or malignant neural lesion arising from a teratoma. Case Report We describe two congenital presacral neuroblastomas. The main clinical differential diagnoses were sacrococcygeal teratoma and meningomyelocele. Pathologically, they lacked teratomatous tissues, lacked germ cell serum markers, were localized without metastases, and were MYCN non-amplified. Both patients have done well without chemotherapy at 18 and 15 months of follow-up. Conclusion Congenital presacral neuroblastoma should be differentiated from teratomatous lesions, and in general have a good prognosis. [ABSTRACT FROM AUTHOR]

Multiple shunt revisions are a formidable challenge in neurosurgery, as the surgeon faces progressive difficulties in finding suitable distal sites for implantation. Gallbladder offers an alternative safe implantation site of distal catheter in case of repeated peritoneal failures. We describe two such cases done in our institute in this brief report. One case has long term functioning shunt, whist other had complications. Relevant literature is also briefly reviewed here. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Atlanto-axial rotatory fixation is fixed rotation of C1 over C2, which may be post-traumatic or post-infective. MATERIALS AND METHODS: We present four cases of atlanto-axial rotatory fixation in children and describe their presentations, pathogenesis, radiological findings, management and follow up findings with review of literature. CONCLUSION: This rare cause should be kept in mind in treating children with painful fixed torticollis. [ABSTRACT FROM AUTHOR]
