Plexiform neurofibromas. Evaluate for changes to known plexiform neurofibromas in patient with neurofibromatosis one. Again seen are multiple masses of increased signal intensity compatible with nerve sheath tumors and the patient's history of neurofibromatosis type I. Lesions are again noted adjacent to both lung apices and along the thoracic nerve roots and intercostal nerves. Subjectively, the overall appearance of the neurofibromas is similar to that seen on prior studies.A reference lesion in the right anterior chest wall measures 2.5 x 1.3 x 3.2 cm (image 25 of series 401, image 11 of series 601).A reference right-sided paraspinal lesion at the level of the thoracic inlet measures 3.3 x 2.1 x 3.4 cm (image 12 of series 401 and image 23 of series 601); the measurement technique is slightly different on the current study than on the prior study, accounting for the increase in numerical measurement values; however, subjectively, the lesion appears similar in size to that seen on the prior study.A reference right paraspinal lesion at the level of the thoracic inlet measures 3.5 x 0.8 x 2.5 cm (image 13 of series 401 and image 27 of series 601), subjectively appearing similar to that seen on the prior study.On the coronal and sagittal sequences, a relatively large neurofibroma is noted anterior to the left psoas muscle, measuring approximately 5 cm in diameter; it appears similar to that seen on the prior study. Numerous subcutaneous and paraspinal masses are also redemonstrated without significant interval change.Although evaluation of the cervical spine is limited on this chest MRI examination there is cervical spondylosis as well as increased signal intensity within the cord at the level of C6 that is comparable to that seen on the prior cervical spine MRI examination.
Neurofibromatosis with multiple neurofibromas appearing similar in size to those seen on the prior study. Other findings as above.
