RESUMO
Disendocrine manifestations during aqueductal stenosis are more and more frequently reported in literature. In the present study, 20 cases of benign aqueductal stenosis associated with disendocrine features as amenorrhea, obesity, polydipsia and polyuria, dwarfism, acromegalic features, hypogonadism, precocious puberty, gigantism are stressed. Authors discuss clinical findings and pathogenetic hypothesis on the base of endocrine, neurological and peculiar radiological features with the support of a wide literature review.

Superior sagittal sinus thrombosis was diagnosed on computerized tomography (CT) scanning and was subsequently confirmed by angiography in two patients. Small ventricles and filling defects occurring within the sinus (the empty triangle sign) appeared to be highly suggestive of superior sagittal sinus thrombosis, and the association was confirmed angiographically. Potential pitfalls in the CT diagnosis of local obstruction of cerebral venous outflow are described and correlated with the natural history of the disease. The need for improved awareness of the CT appearance of occlusive disease of the dural venous sinuses is stressed.
