Enteric cysts are uncommon posterior mediastinal cysts, usually presenting with respiratory symptoms in infancy. We present a rare case of posterior mediastinal enteric cyst extending from below the diaphragm and perforating into the left atrium, causing a thromboembolic cerebral infarct in a 5-year-old boy.
Cerebral involvement associated with juvenile rheumatoid arthritis is rare. It is not influenced by treatment and the presentation can be varied. We describe a case of cerebral infarction secondary to vasculitis in a child with juvenile rheumatoid arthritis.
A 10-year-old girl with mild aortic regurgitation presented with cerebral infarction. Two-dimensional echocardiography showed vegetations on the septal wall of the left ventricular outflow tract without involvement of the aortic valve itself. After successful antibiotic treatment the patient developed an intra-cranial haemorrhage due to rupture of a large intracranial mycotic aneurysm. Consent for surgical treatment of the mycotic aneurysm was not obtained. Twelve months later repeat angiography showed that the aneurysm had undergone spontaneous obliteration.
