35-year-old male with NF1 and multiple plexiform neurofibromas. Again seen are innumerable masses which demonstrate high signal intensity on fluid sensitive sequences, some of which have a target appearance, compatible with nerve sheath tumors and the known history of neurofibromatosis type I. Plexiform lesions are again noted in the soft tissues adjacent to the right lung apex with a smaller concentration of neurofibromas noted within the soft tissues adjacent to the left lung apex. Neurofibromas are again noted along all thoracic nerve roots, bilaterally, with additional neurofibromas involving the intercostal nerves at all levels. Additional solitary neurofibromas of varying size are noted within the musculature and soft tissues of the chest wall. No new lesions are identified.The reference lesion in the right anterolateral chest wall measures 2.4 x 1.4 x 3.5 cm (TR x AP x CC), previously 2.4 x 1.3 x 3.5 cm (image 19; series 501). The reference right-sided paraspinal lesion at the level of the thoracic inlet measures approximately 2.9 x 2.1 x 3.4 cm, previously 3 x 2.1 x 3.5 cm (image 6; series 501).The additional reference right-sided paraspinal lesion at the level of the thoracic inlet measures 3.1 x 1.1 x 2.5 cm, previously 3 x 1 x 2.5 cm (image 7; series 501).There may also be a few small mediastinal nerve sheath tumors which also appear similar to the prior study. Small nerve sheath tumors are also noted within the arms bilaterally, incompletely imaged. We see no specific imaging findings to suggest malignant degeneration within the limitations of this noncontrast examination.
Findings compatible with neurofibromatosis without significant interval change in the reference lesions, with measurements provided above. No new lesions are identified.
