Abstract |
In children, hypothalamic-hypophyseal syndromes such as diabetes insipidus, precocious puberty, growth retardation, and panhypopituitarism can be due either to structural lesions or to functional disorders of the cerebral endocrine complex. When clinical and endocrinological parameters fail to distinguish between these etiologies, neuroradiographical diagnosis becomes extremely important. Although conventional intravenously enhanced computed tomography (IVCT) is satisfactory for the diagnosis of lesions larger than 1 cm, metrizamide CT cisternography (MCTC) greatly improves the diagnostic yield for smaller juxtapituitary masses in the suprasellar cistern, clearly defines their sizes and relationships with contiguous structures, and definitively confirms the diagnosis of empty sella syndrome. Six patients with endocrinopathies and normal or ambiguous IVCT findings are presented to illustrate how MCTC can influence their management and outcome without the patient discomfort and technical complexity associated with pneumoencephalography.
