Abstract

Hypopituitarism represents the consequence of many conditions, in both the adult and child population. It may occur after neurosurgical treatment of brain tumors arising near sella turcica. Much more attention has been focused on lesions far from the hypothalamic-pituitary region as possible causes of pituitary impairment, validating the concept of the particular fragility of these structures. The aim of this study was to evaluate pituitary function in particular GH deficiency (GHD) in patients submitted to neurosurgery for benign tumors of the central nervous system (CNS) not involving hypothalamic-pituitary region. We observed 37 patients with benign brain tumors [13 males, 24 females, age: 54.6±13.9 yr; body mass index (BMI): 25.1±4.0 kg/m2] performing a basic evaluation of the pituitary function and a dynamic test of the GH/IGF-I axis [GHRH (1 μg/kg iv)+arginine (0.5 g/kg iv) test] for 3 and 12 months after the neurosurgical treatment. Some degree of hypopituitarism was shown in 16 patients (43.2%) at the 3-months follow-up. Hypogonadism was present in 4 patients, hypoadrenalism in another 4 and hypothyroidism in 2. Two patients showed mild hyperprolactinemia and no patients had diabetes insipidus. Seven patients (18.9%) were GH deficient (peak GH
