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)
Focal basal meningeal enhancement may produce a confusing CT picture in children with suspected tuberculous meningitis (TBM). To demonstrate the incidence, distribution and appearance of localized basal meningeal enhancement in children with TBM. CT scans of patients with definite (culture proven) and probable (CSF suggestive) TBM were retrospectively(More)
It is estimated that over 90% of children infected with human immunodeficiency virus (HIV) live in the developing world and particularly in sub-Saharan Africa. Pulmonary disease is the most common clinical feature of acquired immunodeficiency syndrome (AIDS) in infants and children causing the most morbidity and mortality, and is the primary cause of death(More)
Vertically transmitted HIV infection is a major problem in the developing world due to the poor availability of antiretroviral agents to pregnant women. HIV is a neurotrophic virus and causes devastating neurological insults to the immature brain. The effects of the virus are further compounded by the opportunistic infections and neoplasms that occur as a(More)
Intracranial tuberculous (TB) abscesses still cause a diagnostic dilemma on both CT and MRI as they may mimic neoplasms. Recognition of TB abscesses may prompt further imaging and appropriate trial of therapy, and may reduce the need for biopsy. To report the CT features of eight intracranial TB lesions in children initially diagnosed as neoplasms and(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)
Lymphobronchial tuberculosis (TB) causes airway compression in 38% of patients. The airway obstruction is conventionally assessed with fibreoptic tracheobronchoscopy (FTB). Multidetector-row spiral computed tomography (MDCT) with three-dimensional volume rendering (3-D VR) has significantly improved the imaging of the airways. No previous studies have(More)
The incidence of tuberculosis (TB) is increasing in both developing and developed worlds, and children, in particular, represent a high-risk group for acquiring the disease. TB of the central nervous system is the most severe, life-threatening form of TB in infants and children. Approximately 10% of all patients with TB have central nervous system(More)
Infundibula are symmetrical funnel-shaped widening, measuring more than 3 mm at its base with the branch artery arising from its apex. The pathological significance of this entity remains controversial. Although a relatively common appearance in otherwise normal angiograms, they have occasionally been described to progress into saccular aneurysms or(More)
