ABSTRACT: Introduction: Spinal schwannomas also known as neurinomas are
often benign slow growing lesion that may develop from Schwann cells of the spinal
roots, it is a nerve sheath tumor. The
authors reported a case of a patient presenting a hyperalgesic lumbosciatica
symptomatic of a spinal schwannoma. Observation: A 36-year-old female patient, with a history of
asthma under treatment was admitted to our
department because of one year lasting of an intermittent fashion bilateral L5
hyperalgesic lumbosciatica. The initial examination has shown back muscles contractures and a segmental deficit of the right
lower limb in L5 and S1, but no genital or sphincter disorders were noted. The
lumbosacral CT scan was without particularity but the magnetic resonance imaging
(MRI) revealed an intradural, extra medullary lesion at the level of L1-L2. A
monobloc resection of the lesion was done. The follow-up is good. Pathology
concluded in schwannoma WHO grade I classification. Conclusion: Lumbar neurinoma that grows slowly
is most often manifested by a radiculalgia often hyperalgesic and disabling.
MRI is the examination of choice to make the diagnosis and complete removal is
possible.
