Neural fibrolipoma is characterized by infiltration of the epineurium by adipose and fibrous tissue. Intradural spinal cases are extremely rare. We report an unusual case of spinal neural fibrolipoma. A 31-year-old pregnant woman presented due to weakness of right leg (muscle strength 2/5). Magnetic resonance (MR) evaluation of the spine revealed an extramedullary intradural mass at the T1-T4 level. MR findings were suggesting a dermoid cyst or a lipoma. Subtotal surgical excision of the tumor was done. Histopathological examination showed enlarged nerve bundles infiltrated by fibroadipose tissue. Thus, the diagnosis of neural fibrolipoma was established. One month after surgery, lumbar MR showed residual tumor tissue, but successful decompression of the spinal cord. Six months after surgery, the neurological examination, muscle strength 4/5 evaluated. Neural fibrolipoma is characterized by infiltration of the epineurium by adipose and fibrous tissue. The tissue grows between and around nerve bundles thereby causing enlargement of the affected nerve. Neural fibrolipoma is a benign lesion with no effective therapy. Surgical excision usually causes severe damage of the involved nerve. Although spinal cases are extremely rare, it should be included in the differential diagnosis of extramedullary intradural masses.

“…Intraneural lipomas are very rare tumours, reported only as single cases. They were most commonly found in the median nerve in the forearm and wrist and single cases have been reported within the ulnar and radial nerves (radial: two cases in posterior interosseous nerve and one in superficial branch of the nerve) [1][2][3][4][5][6][7][8]. All except two reported cases included location of the tumour in the forearm; only two cases were reported on digital nerves [2,9].…”

IntroductionIntraneural lipomas and lipofibromas (also called lipofibromatous hamartomas) are rare, benign tumours occurring in peripheral nerves in the forearm and wrist. They usually present as asymptomatic masses, but if they are large enough, they may cause symptoms of compression neuropathy. Intraneural lipomas and lipofibromas differ with regard to anatomy and clinical behaviour: the former tumour has a well-defined capsule and most commonly occurs within the median nerve in the forearm and wrist. It is diagnosed in the fourth and fifth decades of life and seen more frequently in women. The latter (lipofibroma) has no capsule, is infiltrative in nature, is composed of fatty and fibrous tissue and also most commonly seen in the median nerve. It occurs in a younger age group with no sexual predominance. Due to these differences, these lesions are managed differently 1 2.

“…Intraneural lipomas have a female predominance and, although rare, most commonly occur within the median nerve in the forearm and wrist [4]. Some cases have been reported within the ulnar nerve and radial nerve [5][6][7][8]. All reported upper extremity cases include the forearm proximally to the carpal tunnel and Guyon's canal distally.…”
