- ItemOpen AccessHyperparathyroidism with presumed sellar-parasellar brown tumour based on imaging findings(2006) Said-Hartley, Q; Candy, SBrown tumours are an end-stage complication of hyperparathyroidism. They are relatively rare today, due to earlier diagnosis and prompt treatment of hyperparathyroidism.1 Common locations are the mandible, pelvis, ribs and long bones of the axial skeleton.2 The skull base is an extremely rare site and, for obvious reasons, it is difficult to confirm the diagnosis in the absence of other lesions. In the face of a solitary lesion, a histological diagnosis of a ‘giant-cell tumour’ of benign nature should only be made once hyperparathyroidism has been actively excluded. Brown tumours, solid aneurysmal bone cysts, giant-cell reparative granuloma and giant cell tumour can all appear identical both macroand microscopically.
- ItemOpen AccessA retrospective study of CT angiography versus digital subtraction angiography in penetrating neck trauma(2013) Scholtz, Paul Victor John; Candy, S; Beningfield, SBACKGROUND. Penetrating neck trauma is commonly encountered in South African trauma units, and is associated with high mortality and morbidity rates. The imaging protocol for stable patients with penetrating neck trauma remains controversial. There is only sparse data validating the use of Computed Tomography Angiography (CTA) in the evaluation of penetrating neck trauma. OBJECTIVES. To assess the sensitivity and specificity of CTA versus Digital Subtraction Angiography (DSA) in detecting arterial injury and secondarily evaluate the ability of CT to assess non-arterial injury.
- ItemOpen AccessA review of antenatal MR imaging and correlation with antenatal ultrasound, postnatal imaging and post morem findings(2013) Daire, Arthur; Candy, S; Moosa, STo determine the most common indication for foetal MRI, and to correlate ante-natal MRI with ante-natal ultrasound, post-natal imaging and post mortem findings. This was a retrospective study of imaging between January 2006 and December 2011. Seventy foetal MRI cases with complete medical records (antenatal and postnatal) were included in the study. Antenatal ultrasound and antenatal MR imaging was compared and also compared with the postnatal imaging findings. Stata 12 was used to analyse the Data. Spearman’s test was used to test the agreement between the results. Intracranial pathology was the most common indication for foetal MRI, with ventriculomegaly being the commonest indication determined from prenatal ultrasound. There was 72% agreement between antenatal ultrasound and foetal MRI. Post-natal findings showed 28% agreement with antenatal ultrasound and 39% agreement with foetal MRI. Intracranial pathology was the major indication for foetal MRI. The study found good agreement between prenatal ultrasound and foetal MRI but poor agreement between antenatal and postnatal findings.
