Bilateral pleural metastases of a primary central nervous system neuroblastoma in an adult: First case in the world.

Primary central nervous system neuroblastoma (PCNS-NBL) is a rare and aggressive malignant tumour. Pleural metastases of PCNS-NBL have not been documented before. We report a case of a 30-year-old male patient, with a history of PCNS-NBL treated with surgery, radiation and chemotherapy. Three years later, he presented an aggravated dyspnoea with impaired general condition. The different investigations confirmed that his PCNS-NBL has relapsed with bone, lymph nodes and bilateral pleural metastases. Because of the disseminated disease and the poor general condition of the patient, only symptomatic treatment measures were preconized. The patient died 3 months later following cardiorespiratory arrest. To the best of our knowledge, this is the first case reporting bilateral pleural metastases of a PCNS-NBL in a young adult.
