Description

Cerebral venous thrombosis (CVT) is the most common manifestation of vasculo-Behçet’s and may be superficial and /or deep localization.
The aim of our study was to evaluate the clinical and radiological features of CVT associated with Behcet’s disease in our population and to compare findings with previous studies.
We report a retrospective study of 24 cases of CVT secondary to Behçet's disease, collected between 1999 and 2019 in the neurology department of the Mohamed V Military hospital (Rabat), the Avicenne Military hospital (Marrakech) and the Mohamed VI hospital (Marrakech). The diagnosis of Behçet disease was made in all cases according to the 2014 International Study Group Criteria for Behçet diseases. Patients received antithrombotic treatment, associated with corticosteroids, in 6 cases of superficial CVT and with Immunosuppressants in cases of deep CVT.
Clinical manifestations were dominated by motor deficit in deep localizations and intracranial hypertension in superficial locations. The diencephalic-mesencephalic syndrom was found in 18 patients, whereas intracranial hypertension (71%) and headache (57%) was the most common presentation of superficial CVT. Unlike previous studies, magnetic resonance angiography and conventional angiography performed in our patients confirmed the predominance of deep venous thrombosis (18 cases), whereas superficial CVT was observed only in 6 cases.
