Chronic residual lesions in metastatic medulloblastoma patients

J Pediatr Hematol Oncol. 2014 Jan;36(1):71-5. doi: 10.1097/MPH.0b013e3182843b40.


In a retrospective review of 24 metastatic medulloblastoma patients whose treatment included craniospinal irradiation, 5 patients presented with gross residual abnormalities at completion of therapy. This report describes 2 medulloblastoma patients with persistent residual abnormalities on serial follow-up imaging studies. The patients aged 2 and 2.5 years old at the time of diagnosis underwent surgery followed by multiagent chemotherapy. One patient progressed on therapy and underwent salvage craniospinal radiation. The second showed residual tumor on end of treatment imaging and received low-dose craniospinal irradiation. Despite persistent magnetic resonance imaging findings, the patients are alive and well 13 and 7 years after diagnosis with no further treatment applied. The nature of these residual abnormalities is discussed.
