2-year-old girl with history of NF1 with multiple plexiform fibromas. CHEST:LUNGS AND PLEURA: The lungs appear normal.MEDIASTINUM AND HILA: The heart and pericardium appear normal. The aortic arch is normal. The infiltrative mass described below extends into the anterosuperior mediastinum and displaces the left common carotid and internal jugular veins anteriorly. The arch vessels and tributaries to the left brachiocephalic vein are patent.CHEST WALL: A large, infiltrative T1 and T2 hyperintense mass is seen involving the left neural foramina from C5 to T5. Intradural tumor is identified on the left with slight displacement of the lower cervical/upper thoracic spinal cord to the right. The mass involves the entire left lateral neck and chest wall, extending into the pleural space and laterally into the left axilla beyond the field-of-view.Prominence of the anterior extra-axial CSF space and stenosis in the lower cervical spine is likely postoperative. Please see concurrent MR T-spine for further details.An additional 19 x 12 mm T1 and T2 hyperintense mass is seen arising from the right T7 neural foramen (series 601, image 25) with possible extension through the chest wall.No significant enhancement of this tumor is identified.No muscular atrophy is identified. Skeletal deformities are better characterized on the prior CT.UPPER ABDOMEN: The partially visualized liver and spleen are normal.OTHER
1.Large, infiltrative plexiform neurofibroma involving the left C5-T5 neural foramina, lateral neck, chest wall, and mediastinum.2.Smaller neurofibroma arising from the right T7 neural foramen and probably extending through the chest wall.3.Partially visualized lesion in the right parotid gland which can be further characterized with dedicated imaging if clinically warranted.4.Please see concurrent thoracic spine MR for additional details.
