[Apathy syndrome as a sequela of postoperative irradiation of brain tumors in children].

The somnolence syndrome is a postirradiation syndrome in children. It is to be found after cranial irradiation of chemotherapeutically treated children with ALL (acute lymphocytic leukaemia). Rarely, however, it is a radiation sequela of operated cerebral tumors. We report on such a case of somnolence syndrome, review the literature and discuss the diagnostic and therapeutic problems.
