Spinal neural fibrolipoma: A case report and review of the literature

Abstract

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.

Intradural Conus Medullaris Lipoma With Neurological Deficit: A Rare Occurrence

“…As per the literature, the results are poor, in terms of neurological recovery, if the duration of symptoms is more than two years [7]. Our patient had symptoms of neurological involvement for the last six months and hence, he improved completely at 2.5 years of follow-up, which is in accordance with the literature.…”

Lipoma at Conus Medullaris without Spinal Dysraphism causing Neurological Deficit: A Rare Occurrence

“…6 Partially removing such bulk has yielded positive According to the research, if symptoms last longer than two years, the chances of neurological recovery are minimal. 7 After 2.5 years of follow-up, our patient, who had been having neurological symptoms for the preceding six months, had fully healed.…”

Adult cervicothoracic subpial fibrolipoma without dysraphism: An extremely rare case report

“…While its constituent tissues are conventional epineural structures, some have categorized this lesion as a nerve sheath hamartoma. This condition has been associated with macrodactyly of the digits innervated by the damaged nerve [ 15 ].…”
