Neurofibromatosis type I Brain MRI:There is no evidence of acute ischemic or hemorrhagic lesion on this scan.About 6 mm sized high signal intensity lesion on the right globus pallidus is again seen (best seen on T2 coronal scan), the size and signal intensity do not show any significant interval change since prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.C-spine:There is normal cervical lordosis. The cervical spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. Cervical soft tissue appear to be thickened bilaterally from C2 to C8 with various degrees, this finding does not show any interval change since prior exam on May 23 2014 Cervical spine MRI.There are multifocal various sized lesions (the maximum diameter of the largest one is about 28mm, previously it was 27mm) are found throughout the soft tissue neck, comparing to prior scan, there is no significant interval changes of the numbers, size and MR characteristics since prior scan.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No change of right globus pallidus lesion likely represent hamartoma in terms of size and MR characteristics since prior scan.3. No change of multilevel various degreed cervical nerve root thickenings and multiple soft tissue neck lesions (likely represent neurofibromas) since prior scan. (The right lower neck lesion shows 28mm which was 27mm, but could be related to different scan technique or measurement)
