Abstract

Spinal cord teratomas are rare. There are few reports of teratomas affecting the cervical spine and their association with spondylotic radiculopathy has not been described. A 59-year-old woman with history of fecal incontinence attended with cervical radicular pain radiating to upper limbs. Physical examination showed distal muscle hypotrophy and abolishment of bicipital, tricipital, and brachioradialis reflexes of the right arm, preserving proximal strength. Also, hiporreflexia and loss of proprioception in the right lower limb was observed. Magnetic resonance imaging showed an intramedullary mass at C7-T1, accompanied by intervertebral disk protrusions and dural sac compressions at the same level. One-stage posterior–anterior operative approach for tumor resection, decompression of the radiculopathy and replacement of intervertebral discs was performed. The histopathological diagnosis was for a mature teratoma. We described the first case of an intramedullary cervical teratoma associated with radiculopathy in an adult, providing evidence of rare long-lasting teratomas affecting the cervical spine.

Resumen

Los teratomas medulares son raros. La asociación de teratomas cervicales con radiculopatía espondilótica no ha sido descrita. Una mujer de 59 años con historia de incontinencia fecal acudió con dolor radicular cervical irradiado a miembros superiores. La exploración física reveló hipotrofia distal, arreflexia bicipital, tricipital y braquiorradial del brazo derecho, conservando la fuerza proximal. Se observó hiporreflexia y pérdida de la propiocepción en el miembro inferior derecho. La resonancia magnética reveló una masa intramedular en C7-T1, así como hernias discales y compresión del saco dural en dichos segmentos. Se realizó un doble abordaje posterior-anterior en un solo tiempo para resecar el tumor, descomprimir la radiculopatía y reemplazar los discos afectados. El diagnóstico histopatológico fue de un teratoma maduro. Describimos el primer caso de un teratoma intramedular cervical con radiculopatía espondilótica en un adulto, aportando evidencia sobre los teratomas raros de larga evolución que afectan a la columna cervical.
