34-year-old male with NF1 and multiple plexiform neurofibromas. Please delineate the margins of his tumors. There are innumerable masses of low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, some of which have a target appearance, compatible with nerve sheath tumors and the stated history of neurofibromatosis type I. Plexiform lesions are noted in the soft tissues adjacent to the right lung apex with a smaller concentration of neurofibromas noted in the soft tissues adjacent to the left lung apex. Please note that the brachial plexus is not included in its entirety on this chest study. Neurofibromas are 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. For reference purposes, a tumor in the right anterolateral chest wall is approximately 2.4 x 1.3 cm in transverse dimension and 3.5 cm in oblique craniocaudal dimension. There are a couple of right-sided paraspinal lesions at the level of the thoracic inlet measuring approximately 3 x 2.1 x 3.5 cm and 3 x 1 x 2.5 cm. There may also be a few small mediastinal nerve sheath tumors. Small nerve sheath tumors are also noted within the arms bilaterally. We see no specific imaging findings to suggest malignancy.
Findings compatible with neurofibromatosis as described above.
