RESUMO
We have reviewed the clinical features, together with the radiographs and computerised tomography, in 9 patients with tuberculosis of the vertebral body and neural arch. All presented with paraparesis or paraplegia. The morbidity associated with this disease is so serious that it is essential to have an accurate means of evaluating the lesion as early as possible. Routine radiographs can only indicate the level of the disease and the loss of disc space, but cannot define the full extent of the lesion. Computed tomography shows details of the tuberculous involvement of the neural arch, as well as the vertebral body and spinal canal; the site and extent of the soft tissue lesions can also be seen. This is essential for evaluation of the neural arch involvement which will enable the clinician to select the appropriate treatment, and so prevent neurological complications.

A review of paediatric brainstem gliomas (BSGs) treated in the Department of Radiation Oncology of the University of the Witwatersrand teaching hospital group is presented. Eleven patients between the ages of 4 years and 9 years were seen in the period 1982-1992. Of these cases, 9 were diffuse, 1 focal and 1 exophytic; the radiological features classifying these primary brainstem tumours are described. The survival from initiation of treatment was longest for the exophytic type BSG (72 weeks), while little difference in survival between the 9 diffuse type BSGs (mean 21.5 weeks) and the single focal type BSG (21 weeks) was found. The treatment is described and the role of hyperfractionated radiotherapy is reviewed.

Hepatocellular carcinoma (HCC) rarely presents as biliary tract occlusion [1,2]. Intralumenal iridium-192 brachytherapy has been used to treat extrahepatic bile duct carcinoma and may be curative if the macroscopic tumour has been resected surgically [3]. We describe a rare event, a case of HCC presenting with biliary tract occlusion treated with intralumenal iridium-192 brachytherapy.
