Adult-onset ganglioneuroblastoma of the posterior mediastinum with osseous metastasis.

Ganglioneuroblastomas are a member of the neuroblastic family of tumors most commonly seen in children but they may also occur in adults. Ganglioneuroblastomas have metastatic potential and, like other neuroblastic tumors, osseous metastasis is possible. Imaging features of ganglioneuroblastomas tend to be variable. We describe a case of an adult female who developed a ganglioneuroblastoma of the posterior mediastinum that metastasized to the thoracolumbar spine, highlighting rarely documented osseous metastasis.
