Lymphobronchial tuberculosis (TB) is tuberculous lymphadenopathy involving the airways, which is particularly common in children. To describe CT findings of lymphobronchial TB in children, the parenchymal complications and associated abnormalities. CT scans of children with lymphobronchial TB were reviewed retrospectively. Lymphadenopathy, bronchial(More)
SETTING Cape Town, South Africa. OBJECTIVE To improve the reading of chest X-rays (CXRs) in child tuberculosis (TB) suspects. DESIGN We designed a reporting and recording form to assist in the diagnosis of childhood TB from CXRs. We then developed an image bank of antero-posterior and lateral CXR pairs, with each image pair assigned to one of four(More)
Cavitating pulmonary tuberculosis (PTB) is generally known as a disease of adults, with children typically having features of primary PTB. To group children with PTB and cavities according to possible pathogenesis by evaluating the clinical and radiological findings. The clinical and radiological findings in ten randomly selected children with PTB and(More)
PURPOSE To show that necrotic areas of the lung demonstrated on computed tomographic scanning in children with primary pulmonary tuberculosis (TB) may be of low signal intensity on T2. MATERIALS AND METHODS Review of magnetic resonance imaging scans (T1/T2/STIR/postgadolinium T1) in 6 children scanned because of low-density necrotic areas demonstrated on(More)
Pulmonary involvement in Kaposi sarcoma is rare in children and can be difficult to distinguish from other pathology. To describe the radiological findings in paediatric pulmonary Kaposi sarcoma. Sequential chest radiographs of six children and CT scans of four of these children were evaluated retrospectively. Their ages ranged from 18 months to 10 years;(More)
Lymph gland involvement of the airways is common in young children with pulmonary tuberculosis. This lymph gland involvement leads to lymphobronchial tuberculosis, which presents with varying degrees of airway obstruction. These children are best assessed by fibreoptic bronchoscopy and are treated with the normal anti-tuberculosis regimens to which(More)
Infection of the lungs and airways by viral, bacterial, fungal and protozoal agents, often producing atypical radiographic features, is common in children with human immunodeficiency virus (HIV) infection. Conventional chest radiography and chest CT remain the most useful imaging modalities for evaluation of the immunocompromised patient presenting with a(More)
Involvement of the oesophagus by tuberculosis is rare, and erosion and perforation of the oesophagus by tuberculous lymphadenopathy is an unusual complication of primary pulmonary tuberculosis. There are very few reports describing both CT and contrast swallow appearances of these lesions. To describe the CT and contrast swallow appearances of oesophageal(More)
Clinical signs of paediatric pulmonary tuberculosis (TB) include stenosis and deformation of the airways. This paper presents two methods to analyse airway shape and detect airway pathology from CT images. Features were extracted using (1) the principal components of the airway surface mesh and (2) branch radius and orientation features. These methods were(More)
