27-year-old female with NF1 with shooting pains into middle two fingers of the right hand. Evaluate for any evidence of lesion in the median nerve. Multiple lesions are present which demonstrates isointense signal to skeletal muscle T1-weighted images and hyperintense signal to skeletal muscle on T2-weighted images are present throughout the course of the median nerve which demonstrate enhancement after intravenous contrast administration, the largest of which measures 3 mm x 3 mm (series 501, image 14). The median nerve appears thickened throughout its course. Multiple lesions are present throughout the course of the ulnar nerve, the largest of which measures 6 mm x 5 mm x 13 mm (series 501, image 10) located in the distal forearm approximately 2 cm proximal to the carpal tunnel and corresponds to the reference lesion on MRI study of the forearm.The tendons and muscles of the wrist appear normal. Bone marrow signal intensity is normal.
Findings compatible with neurofibromas affecting the median and ulnar nerves with measurements provided above.
