ABSTRACT
BACKGROUND: Cerebral venous sinus thrombosis (CVST) in children is associated with a high incidence of serious morbidity and mortality. The presenting features are variable. It can be diagnostically challenging and the optimal treatment is uncertain. AIM: To describe the features of a series of children with CVST treated in a single paediatric neurology centre and to discuss the role of local thrombolysis. METHODS: Electronic databases were searched using diagnostic labels and International Classification of Diseases (ICD) codes to identify children aged 1 month to under 17 years with CVST. Their records were reviewed. RESULTS: 21 children were identified over a period of 8.25 years with a median age of 7.1 years. The presenting symptoms included headache (15 children), vomiting (14 children) and visual disturbance (eight children). Signs found included papilloedema (16 children), fever (six children) and sixth nerve palsy (six children). The most common underlying condition was middle ear infection (13 children). All cases received unfractionated heparin and four severe cases received local pharmacological thrombolysis. 48% of cases had an adverse outcome (death, chronic intracranial hypertension, residual hemiparesis or sixth nerve palsy). DISCUSSION: CVST has non-specific presenting features and a high risk of significant morbidity. CVST is typically found in association with a predisposing condition. Although heparin is the mainstay of treatment, thrombolysis may reverse deterioration as seen in three cases in this series. However, there is insufficient evidence to recommend the routine use of thrombolysis at present.

We report a case of pneumothorax as a result of positive pressure ventilation in a child previously treated for empyema. Three months following discharge for successful treatment of empyema our patient received a general anesthetic for an elective MRI of the brain for investigation of nystagmus. During recovery from the anesthetic he developed respiratory distress and was found to have a loculated pneumothorax. We propose that pleural fragility in childhood empyema possibly persists even after clinical resolution and in this case for up to 3 months. The complication of pneumothorax should be considered in all patients receiving positive pressure ventilation following resolved empyema.
