D. Frappaz et al., ISOLATED INTRASPINAL RELAPSE OF NEUROBLASTOMA AFTER AUTOLOGOUS BONE-MARROW TRANSPLANTATION, Pediatric hematology and oncology, 11(4), 1994, pp. 439-443
Neuroblastoma may present with spinal cord compression due to dumbbell
extension of thoracic or abdominal disease. Isolated intraspinal invo
lvement as the sole site of relapse is rare. Two infants with poor-pro
gnosis stage IV neuroblastoma presented early after high-dose therapy
and autologous bone marrow transplant with isolated spinal relapse her
alded by misleading symptoms. The rarity of such isolated relapses is
reviewed, and an etiologic hypothesis is proposed.
