[Radiotherapy of paraplegia caused by extramedullary hematopoietic tissue].
The presentation by computed tomography of an extramedullar epidural intraspinal hemopoisis has only been described sporadically. It has been possible to visualize by CT-scans the regression under radiotherapy of a sensory and motor paraplegia in a 17 years old patient with beta-thalassemia major. The central nervous system (thoracic and lumbar zone as well as os sacrum) was exposed to a total reference dose of 30 Gy which was administered within twenty days by a 60Co unit in single doses of 2 Gy each. From 4 Gy on, the paraplegic symptoms regressed continuously. The control CT taken after 26 Gy- the paraplegia had completely disappeared at this time-showed a significant regression of the intraspinal soft tissue masses. Radiotherapy is very important in the treatment of this disease. A direct correlation is found between clinical symptoms and CT-presentation.
