Background: Craniopharyngioma is a non-malignant embryonic tumour in the pituitary-hypothalamic area, associated with hypothalamic obesity. Dysfunctional parasympathetic nervous system activity has been proposed as one mechanism underlying alterations in energy metabolism. Arterial spin labelling (ASL) is a non-invasive MRI technique that quantifies brain tissue perfusion as a proxy for functional activity. Here, we measure cerebral perfusion in patients with ...

Background: Craniopharyngioma is a non-malignant, embryological brain tumour in the sellar and parasellar region. Hypothalamic damage is common and accompanied by development of obesity in at least 50% of cases. Mechanisms underlying hypothalamic obesity in craniopharyngioma patients however remain unclear and treatment options are invasive and limited. This feasibility study included a novel application of functional neuroimaging, an established method in obe...

Background: Craniopharyngioma is a rare, suprasellar tumour, which, together with associated surgery or radiotherapy, results in damage to the hypothalamus and severe obesity in approximately 50% of cases. The multi-factorial mechanisms underlying the development of obesity in craniopharyngioma are not well understood. Hypothalamic damage in craniopharyngioma has been associated with dysfunctional parasympathetic nervous system activity leading to altered gluc...
