Abstract
Background

Pancreatic cancer is a common gastrointestinal malignancy, and is often associated with a poor prognosis. Although liver is generally seen as a distant metastasis point, it has been shown that it can metastasize to any organ, especially the gastrointestinal tract, and approximately 0.3% of metastases are observed in spinal cord.

Case description

We report a 36-year-old woman with a prior history of pancreatic adenocarcinoma who presented to us with a thoracic intramedullary lesion and recent onset of neurological deficits. She underwent surgery with histological confirmation of a diagnosis of metastatic adenocarcinoma.

Conclusion

To our knowledge there is no prior report of pure intramedullary spinal cord metastasis from a pancreatic adenocarcinoma in the literature. We report the present patient in view of the rarity of intramedullary spinal cord metastasis and its clinical significance. Although intramedullary metastases are rare, they should be investigated in every patient with malignancy and progressive neurological deficit. While its general prognosis is poor regardless of the type of treatment, early diagnosis and treatment is important in terms of quality of life and survival.

Resumen
Antecedentes

El cáncer de páncreas es una neoplasia maligna gastrointestinal común y, a menudo, se asocia con un mal pronóstico. Aunque el hígado generalmente se ve como un punto de metástasis distante, se ha demostrado que puede hacer metástasis a cualquier órgano, especialmente al tracto gastrointestinal, y aproximadamente el 0,3% de las metástasis se observan en la médula espinal.

Descripción del caso

Presentamos una mujer de 36 años con antecedentes de adenocarcinoma de páncreas que se presentó con una lesión intramedular torácica y de reciente aparición de déficits neurológicos. Fue intervenida quirúrgicamente con confirmación histológica de diagnóstico de adenocarcinoma metastásico.

Conclusión

Hasta donde sabemos, no existe en la literatura ningún informe previo de metástasis intramedular pura de la médula espinal de un adenocarcinoma pancreático. Presentamos el presente paciente en vista de la rareza de la metástasis intramedular de la médula espinal y su importancia clínica. Aunque las metástasis intramedulares son raras, deben investigarse en todo paciente con neoplasia maligna y déficit neurológico progresivo. Si bien su pronóstico general es malo independientemente del tipo de tratamiento, el diagnóstico y el tratamiento precoces son importantes en términos de calidad de vida y supervivencia.
