Clinical manifestations and radiologic findings in craniopharyngiomas in adults

The clinical and histopathologic findings in two adults with craniopharyngioma emphasized the wide age range and diverse initial manifestations of this tumor. A retrospective clinical review of 49 additional patients substantiated these points and disclosed that over 40% were initially examined by ophthalmologists. The initial manifestations fell into four broad categories: (1) visual system abnormalities (77% of the cases), (2) headache (67%), (3) endocrinologic abnormalities (57%), and (4) mental status abnormalities (19%). The frequency of these manifestations varied slightly among different age groups. The radiologic features in the two patients described (a 75-year-old man and a 38-year-old woman) included a distinct appearance on computed tomographic scans. These craniopharyngioma were not calcified and were isodense without contrast but enhanced densely and uniformly with contrast, simulating an aneurysm of the circle of Willis.
