Description
Summary:The association between motor tics and cervical myelopathy is rare and not well understood. Only a few papers in the literature reported this disorder until the present date. This is a case report of a cervical myelopathy case secondary to a motor tic disorder. A 23-year-old male with a 10-year history of motor tic disorder, involving sudden forced extension of the head and cervical spine. Disturbed tactile sensation and kinetic posturing that progressed to the Lhermitte sign every time he made the movement were detected over the last six months. Magnetic resonance imaging (MRI) showed hyperintense intramedullary lesion at C2-C3, degeneration at C3-C4, and no signs of spinal cord compression. On sagittal view, functional MRI with head extension showed anterior compression with protrusion of the intervertebral disc and posterior compression of the yellow ligaments causing spinal cord stenosis. Anterior discectomy and fixation of C3-C4 were performed. There were no complications. The patient showed improvement and the motor tics were controlled by haloperidol. The patient remains symptom-free after 2 years of follow-up. Uncontrolled motor tics can compromise spinal cord function. Functional MRI can reproduce the abnormal movements and clarify the physiopathology. La asociación entre tics motores y mielopatía cervical es rara y no es bien comprendida. Pocos estudios, que analizan este disturbio, han sido encontrados en la literatura hasta el momento. Este es el relato de un caso de mielopatía cervical secundaria a tics motores. Paciente masculino de 23 años con historial de trastorno de tic motor desde hace diez años, involucrando extensión forzada de la cabeza y columna cervical. En los últimos seis meses, se diagnosticaron deficiencias de sensaciones táctiles y postura cinética que progresaron hacia la señal de Lhermitte, cada vez que el paciente se movía. La Resonancia Magnética (RM) reveló lesión intramedular hiperintensa al nivel de C2-C3, degeneración al nivel de C3-C4, y ausencia de señales de compresión medular. En la visión sagital, la RM funcional con extensión de la cabeza reveló compresión anterior con protrusión del disco intervertebral, y compresión posterior de los ligamentos amarillos, causando estenosis medular. Se realizó discectomía anterior y fijación de C3-C4. No hubo complicaciones. El paciente presentó mejora y los tics motores fueron controlados por haloperidol. Luego de 2 años de acompañamiento, permanecía libre de los síntomas y tics
