Rare Co-occurrence of Spinal Cord Hemorrhage from Radiation-induced Cavernous Hemangioma and Classical Hodgkin Lymphoma Post-transplant Lymphoproliferative Disorder

Post-transplant lymphoproliferative disorders (PTLDs) are lymphoproliferative diseases that occur after solid organ transplantation or hematopoietic stem cell transplantation (HSCT). The development of PTLD is often associated with reactivation of Epstein-Barr virus (EBV). A 26-year-old woman with a history of HSCT and total-body irradiation developed spinal cord hemorrhage from a radiation-induced cavernous hemangioma (RICH) shortly after the development of classical Hodgkin lymphoma PTLD with EBV reactivation. Although little is known about the factors leading to hemorrhagic events from spinal cord RICH, we suspect that EBV reactivation may have been a factor contributing to the hemorrhage in the present case.

Sudden spinal hemorrhage in a pediatric case with total body irradiation-induced cavernous hemangioma

Compared to cerebral radiation-induced cavernous hemangiomas (RICHs), little is known about intraspinal RICHs. A 13-year-old male suddenly developed symptomatic spinal hemorrhage eight years after hematopoietic stem cell transplantation using a total body irradiation (TBI) based myeloablative regimen. A solitary small hemangioma was detected on follow-up T2 star weighted magnetic resonance imaging of the spine. His neurological symptoms gradually improved with supportive treatment and rehabilitation, although he experienced rebleeding 2 years later. Intraspinal RICH is very rare but should be recognized as a possible late adverse effect in pediatric patients who received TBI.
