Brown Tumor Related to Secondary Hyperparathyroidism Leading to Spinal Cord Compression Syndrome

Abstract

Brown tumor is a benign bone injury, which occurs only in the presence hyperparathyroidism. The involvement of the spine is relatively rare and therapeutic procedures are not yet fully established in these cases. We report a case of a chronic renal patient with a spinal cord compression syndrome at the level of T6, due to a brown tumor related to secondary hyperparathyroidism. The treatment of brown tumor should be directed to the control of hyperparathyroidism; however, there are insufficient data until this moment, and when spinal cord compression occurs, the surgical decompression should be considered.

Resumo

Tumor marrom consiste numa lesão óssea benigna, que ocorre somente na presença de hiperparatireoidismo. O envolvimento da coluna vertebral é relativamente raro e a conduta terapêutica ainda não foi completamente estabelecida nesses casos. Relatamos o caso de um paciente com insuficiência renal crônica e síndrome de compressão medular ao nível de T6 devido a tumor marrom relacionado ao hiperparatireoidismo secundário. O tratamento do tumor marrom deve ser direcionado ao controle do hiperparatireoidismo, entretanto, não existem dados suficientes até o momento e, quando ocorre compressão medular, a descompressão cirúrgica deve ser considerada.
