Surgical treatment of craniopharyngioma often leads to a rapid and dramatic weight gain, leading to hypothalamic obesity. Treatment focused on the diet, physical activity, and different types of drugs have very often provided unsatisfactory results. To date, no data have been reported on hypothalamic obesity (HO) regarding the use of semaglutide, a novel type 1 receptor glucagon-like peptide-1 agonist, to limit body weight gain after surgical removal of a neoplasm, despite its already documented efficacy in obesity treatment. In this case report, we tested semaglutide in an 18-year-old patient with HO induced by a surgical intervention for craniopharyngioma. A very favorable treatment response was found in terms of body weight reduction and improvement in metabolic parameters. Our patient lost more than than 30 kg after only 6 months of therapy, which has never been reported before in the literature on HO.

Cerebellar mutism syndrome (CMS) represents a major complication affecting many children that undergo surgery for posterior fossa lesions. Etiology and pathophysiology are still not fully understood. CMS deeply influences quality of life and recovery of these patients. An effective treatment has not been defined yet. This case-based review aims at analyzing the available evidence and knowledge to better delineate this phenomenon and to determine whether CMS can be successfully treated with pharmacological therapy.
Systematic research and retrieval of databases were conducted analyzing all papers where medical treatment of CMS was reported. A summary of the latest understanding and reports regarding definition, clinical manifestations, pathophysiology, management, and outcome of CMS has been conducted.
Consensus on definition of this syndrome is lacking. CMS is the term accepted by the Posterior Fossa Society in 2016. Pathophysiology is still poorly understood but the most likely mechanism is injury along proximal components of the efferent cerebellar pathway. Nine papers describing positive effects of pharmacological therapy for CMS have been identified. Fluoxetine, zolpidem, bromocriptine, and midazolam are the drugs that seem to alleviate symptoms of CMS and improve recovery. To date, cognitive rehabilitation and physiotherapy are the only treatment options available.
CMS has deep impact on affected children and their families. Despite attempts to identify preventive measures and treatment, cases still occur on a regular basis. Pharmacological treatments have been proposed to help reduce the symptoms of CMS with some promising results, but reports are limited; therefore, further studies are needed.
