ISOLATED EXTRAMEDULLARY RELAPSE OF ACUTE LYMPHOBLASTIC-LEUKEMIA PRESENTING AS AN INTRASPINAL MASS

Leptomeningeal relapse is a common finding in acute lymphoblastic leuk emia (ALL), but a solid intraspinal mass with cord compression as the sole site of extramedullary relapse is unusual. We report an adult pat ient with ALL, after 2 years of complete remission, who developed a sp inal cord compression due to an intraspinal mass as a first manifestat ion of extramedullary relapse. Manifestation of first relapse in ALL p resenting as an intraspinal mass is rare and may be added to other unu sual extramedullary sites of relapse.
