Los paragangliomas son tumores neuroendocrinos que habitualmente se originan en la médula adrenal y sistema paraganglionar. La localización en la cauda equina es infrecuente, por lo que habitualmente se confunden con otros tumores observados con mayor frecuencia en esta región como schwannomas y ependimomas. Se presentan dos casos de paragangliomas de la cola de caballo, estudiados con resonancia magnética (RM), que debutaron clínicamente con dolor lumbar de larga evolución. Se discuten los hallazgos radiológicos, actitud terapéutica y estudios neuropatológicos realizados.
Paragangliomas are neuroendocrine tumors that usually arise from the adrenal medulla and paraganglias. Location at cauda equina level is extremely infrequent, explaining that they are usually confused with other more frequent tumors at this location like schwannomas and ependymomas. We report two more cases of paraganglioma of the cauda equina, that were studied with magnetic resonance imaging (MRI), in two patients with long lasting low back pain. We review the MRI findings and discuss the therapeutic approach and hystopathological appearance.
