title: Computerised tomography in the evaluation of expansile lesions arising from the skull vault in childhood--a report of 5 cases.
abstract: Expansile lesions of the skull vault are rare in childhood, and often present as relatively asymptomatic calvarial swellings. The cases of 5 children with expansile lesions of the skull vault due to both benign and malignant primary bone lesions are described. The value of computerised tomography in demonstrating that the "tumour" arises primarily from the skull vault as opposed to the underlying brain, and in demonstrating clinically unsuspected endocranial extension of the mass is described. The CT findings in 2 cases of aneurysmal bone cyst, including the significance of the presence of "fluid levels" in reaching a definitive diagnosis are discussed. The successful pre-operative embolisation in one case of aneurysmal bone cyst is reported.
