8-year-old male with type I neurofibromatosis and persistent low thoracic back pain. The thoracic vertebrae demonstrate normal alignment without evidence of fracture or subluxation. There is no evidence of cord signal abnormality or stigmata of neurofibromatosis 1. There is no compromise to the central spinal canal or neural foramina.There is a small oval focus of enhancement along the upper mediastinum on the right side, which likely represents a paratracheal lymph node and does not appear pathologically enlarged. An incidental splenule is also noted.
Normal MRI of the thoracic spine.
