Reason: any internal plexiform neurofibromas? History: man with NF1 who has severe daily pain, some of which seems superficial; he also has recurrent vomiting Limited study secondary to motion artifact.There is normal appearance of the liver, spleen, pancreas, adrenal glands, and kidneys. No focal masses are identified within the organs. There is no hydronephrosis or nephrolithiasis. No evidence of bowel obstruction. The bladder appears normal. No significant lymphadenopathy.Multiple small cutaneous neurofibromas are seen within the superficial soft tissues of the abdomen and pelvis. The largest in the right hemiabdomen measures 2 x 1 cm, and demonstrates expected T2 hyperintensity.Additionally, multiple neurofibromas are seen along the lower lumbar nerve roots, best appreciated on coronal image is 18-20 (these are better assessed on previous lumbar spine MR of 10/11/16).No large intraperitoneal/retroperitoneal mass is identified.
