Reason: any paraspinal neurofibromas? History: girl with nf1 and rather severe lower back pain. There is an incompletely characterized T2 hyperintense lesion that measures up 11 mm in the right posterior abdomen lateral to the psoas muscle at the level of L3-4. There is disc space narrowing and decreased T2 signal within the L3-4 disc with associated endplate marrow signal alterations. However, there is no significant spinal canal or neural foramen stenosis. There is an ovoid T2 hyperintense lesion in the right S2-3 neural foramen that measures 6 mm in width. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. The spinal cord displays normal signal and morphology. There is a partially-imaged cystic left adnexal structure.
1. An ovoid T2 hyperintense lesion in the right S2-3 neural foramen that measures 6 mm in width may represent a perineural cyst or neurofibroma. Characterization is limited without intravenous contrast.2. An incompletely characterized T2 hyperintense lesion that measures up 11 mm in the right posterior abdomen may represent a neurofibroma among other possibilities. Dedicated abdominal imaging may be useful for further evaluation.3. Degenerative disc disease at L3-4 without significant spinal canal or neural foramen stenosis.4. Partially-imaged cystic left adnexal structure. Dedicated pelvic imaging may be useful for further evaluation.
