Hydatid disease is an endemic zoonotic disease in many areas of the world. An intracranial hydatid cyst is a relatively rare entity, accounting for only 1–2% of all intracranial space-occupying lesions. Most commonly they are seen in children and young adults. Here, we present 9 cases of pediatric intracranial hydatid cyst operated at Sher-I-Kashmir Institute of Medical Sciences, Srinagar, India, between 2009 and 2015. The mean age of presentation was 11.5 years. The male to female ratio was 5: 4. In 7 cases, a history of contact with pet dogs was present. Seizure was the most common finding, present in 7 cases. Seven patients had solitary cysts and 2 had multiple cysts on presentation. All patients were operated on, and recurrence was observed in 2 patients. The features of this rare disease are retrospectively analyzed in this presentation and the literature is reviewed.

Spinal osteochondromas must be considered as rare etiology of spinal cord or root compression in the pediatric age group and utmost care should be taken while excising these benign lesions.

Primary intracranial melanoma is an uncommon entity and only case reports have been published in the literature. We report a case of an elderly male who was operated with a preliminary diagnosis of meningioma, but it proved to be a histological surprise as it came out to be melanoma with no primary anywhere in the body.

Primary central nervous system lymphoma is a well-known entity. However, the hypothalamus is a rare location, especially in adults. Few cases of secondary lymphomas have been reported. We report a case of primary hypothalamic lymphoma in an adult male with normal pituitary functions. Lymphoma should be considered as one of the differential diagnosis of lesions involving the hypothalamic/third ventricular area.

Background: Post-craniectomy hydrocephalus in patients with intracranial hypertension is becoming a major concern for neurosurgeons because of the increasing number of hospital admissions for head trauma, stroke and other lesions which may lead to severe brain oedema requiring decompressive craniectomy. Methods: We collected records of all the paediatric patients who developed hydrocephalus following decompressive craniotomy from October 2011 to October 2013 and analysed their clinical profiles. Results: We had 3 patients in this group, ranging in age from 6 to 18 years; 1 patient died and the other 2 patients continue to remain in follow-up. Conclusion: Post-traumatic hydrocephalus is one of the rare complications of decompressive craniotomy; CSF diversion remains the only option for improvement in neurological status.
