Grisel syndrome, sigmoid sinus thrombosis and rheumatic carditis: Case report of a rare association

Abstract

Grisel's syndrome (GS) is a non traumatic atlanto-axial rotatory subluxation of C1-C2 joint. A six year old girl, 20 days after an episode of fever, developed a torticollis and a 3/6 heart murmur. The echocardiography showed a Rheumatic Carditis. The Brain and cervical spine Magnetic resonance imaging (MRI) and the Computerized Tomography (CT) showed rotary dislocation of C1-C2 vertebrae, compatible with GS, and cerebral venous thrombosis (CVT). An antibiotic therapy, Prednisone and a low molecular weight heparin for 7 days was prescribedfollowed by an oral anticoagulant for 6 months. After a month the MRI showed a reduction of the dislocation and cerebral venous recanalization.
