Reason: patient has a cutaneous neurofibroma just above the right inguinal area. It is unusually painful. Is there any evidence of deep extension or deep tumor? History: boy with NF1 and painful right inguinal area Thickening and diffuse signal abnormality is noted in the left gluteus musculature extending into the deep soft tissues and extending to the left perirectal soft tissues and displacing the rectum to the right, as best visualized on image 30 of series 3, appearing slightly more extensive as compared to prior exam. Additional more focal area of signal abnormality in the right superior anterior thigh region measuring 2.4 x 0.6 cm on image 27 of series 3 compatible with neurofibroma and is increased in size. Additional neurofibroma noted along the deep fascial planes of the left thigh seen on image 30 of series 3 is unchanged. Scattered diffuse cutaneous neurofibromas are noted in bilateral lateral and posterior aspects of the pelvis and are increased in number and size.
1.Diffuse signal abnormality in the left gluteus musculature extending into the the perirectal soft tissues and mildly displacing the rectum, increased in size as compared to prior exam.2.Numerous scattered cutaneous neurofibromas, increased in size and number, as above.
