Intraventricular neurocytoma presenting as Kleine-Levin syndrome: resolution after resection and review of neurosurgical conditions associated with hypersexuality. Illustrative case

Key Points

• To explore the relationship between intraventricular neurocytomas and secondary Kleine-Levin syndrome and the effects of tumor resection.
• Case report detailing an individual with intraventricular neurocytoma presenting as secondary Kleine-Levin syndrome.
• Surgical intervention involving tumor resection.
• Review of neurosurgical conditions linked to hypersexuality and their implications.
• The surgical resection of the tumor resulted in resolution of the Kleine-Levin syndrome symptoms.
• Increased frequency of hypersexuality was noted in cases of neurosurgical diseases affecting the right hemisphere.
• Limited case reports highlight the need for further observations on these associations.
