Adult-onset giant mediastinal neuroblastoma.

Background: Neuroblastoma is a neurogenic tumor typically diagnosed in children <5 years of age. It arises from immature neural crest cells of the medulla of the adrenal gland or, less commonly, along the paravertebral sympathetic chain. We hereby report a patient with adult-onset giant mediastinal neuroblastoma.

Case description: A 34-year-old female presented with mid-thoracic back pain radiating to the ribs for 1 month. The neurological examination showed decreased sensation at the left T6-T12 dermatomes. Radiological imaging revealed a giant left mediastinal paravertebral soft-tissue lesion. The patient underwent a posterolateral thoracotomy and resection of the lesion. The histopathological sections were compatible with mediastinal neuroblastoma (Differentiating subtype).

Conclusion: Adult-onset neuroblastoma has been rarely reported in the literature. The present article discusses the clinicoradiological features of an adult patient with giant mediastinal neuroblastoma.
