Male 35 years old Reason: Evaluate plexiform neurofibroma History: NF1, known plexiform tumors in chest Redemonstration of innumerable masses with increased signal intensity on fluid sensitive sequences, again compatible with nerve sheath tumors and history of neurofibromatosis type I. Lesions are again noted in the soft tissues adjacent to the right lung apex, with additional small concentration of lesions adjacent to the left lung apex. Lesions along the thoracic nerve roots and intercostal nerves at all levels. No new lesions are identified.Reference lesion in the right anterior chest wall measures 2.7 x 1.2 x 3.1 cm (image 23 series 401; image 10 series 601) previously 2.4 x 1.4 x 3.5 cm.Reference right-sided paraspinal region at the level of the thoracic inlet measures 2.9 x 2.0 x 3.5 cm (image 8 series 41; image 22 series 601) previously 2.9 x 2.1 x 3.4 cm.Reference right-sided paraspinal lesion at the level thoracic inlet measures 3.0 x 0.9 x 2.5 cm (image 10 series 401; image 25 series 601) previously 3.1 x 1.1 x 2.5 cm.No specific evidence of malignant degeneration on this noncontrast MR examination.
Findings are again compatible with neurofibromatosis, with significant interval change of index lesions or evidence of new lesions.
