Introduction Cerebral venous thrombosis (CVT) is uncommon with a variable clinical presentation.

Heparin is used for first-line treatment in association with symptomatic and etiologic management.

Methods A retrospective review of the medical and radiological records of patients with CVT was managed in the Paediatric Intensive Care Unit, Faculty of Medicine- Oran University, Algeria over a six-year period.

We attempt to determine the clinical, radiological, etiologic and prognostic characteristics of CVT in this age range.

Results From 2008 to 2013, 05 children had cerebral venous thrombosis. Their ages ranged from 29 days to 10 years. Transient seizures (4 children), convulsive status epilepticus (1 patient) and focal neurologic signs (2 children) were the first clinical symptoms.

The presence of longitudinal (3 patients) and lateral (2 patients) sinus thrombosis was suggested by unenhanced CT scan, confirmed by magnetic resonance angiography, with absence of blood flow in the longitudinal sinus,

Thrombosis was associated with predisposing factors in all cases. Numerous causes or predisposing factors were identified: infections in 4 patients and non infectious causes in 3 patients.

Treatment consisted of anticoagulation in all cases, followed by oral anticoagulation.

The general outcome was good; in fact we observed a complete recovery.

Conclusion Diagnosis of sinus thrombosis can be made more accurately and noninvasively by angio-MRI.
