“…Motor and sensory deficits, as seen in our patient, rarely occur ( 3 ). Schwannomas can develop anywhere along the course of the sciatic nerve causing radiculopathy ( 4 , 5 ). These tumors may be sporadic and solitary or multiple, as in neurofibromatosis type 1 (NF1).…”

“…Motor and sensory deficits, as seen in our patient, rarely occur ( 3 ). Schwannomas can occur anywhere along the course of the sciatic nerve causing radiculopathy ( 4 , 5 ). Interestingly, in our patient, the lumbar radiculopathy was caused by a schwannoma at the T7 dorsal nerve root tumor as it exits through its foramen, compressing the adjacent lumbar spinal cord and lumbar nerve roots as they course down to exit through the lumbar foramen.…”

Compression or irritation of the sciatic nerve and its branches, the common fibular and tibial nerves, causes sciatica which is a common syndrome characterized most often by radiating pain from the lower back down the legs and also manifesting as sensory and motor deficits. Sciatica is a common presentation of lumbosacral disc prolapse and degenerative disease of the lumbar spine in ambulatory settings. Schwannomas rarely cause sciatica; hence, it is seldom considered in evaluation of a patient with radiculopathy. Our patient presented with lumbar radiculopathy, mild degenerative changes on lumbar magnetic resonance imaging (MRI) scan, and failed conservative treatment. Myelopathy was confirmed with electromyogram (EMG). Thoracolumbar spine MRI revealed the schwannoma in the thoracic region. He recovered neurologic function after tumor excision. This case highlights the diagnostic challenge that may arise in evaluating a patient with lumbar radiculopathy, negative lumbosacral spine imaging, and failure of conservative therapy.

“…Incidence of foraminal tumours is 1–5%; schwannomas being the most common (60%) [ 2 ]. There have been reports of neurilemoma involving the sciatic nerve in the extraforaminal course in the pelvis, thigh and peripheral portion presenting as sciatica [ 3 , 4 ]. There is paucity of literature describing foraminal neurilemoma involving the lumbar root presenting as sciatica [ 2 , 5 , 6 ].…”

Sciatica is commonly caused by lumbar prolapsed intervertebral disc (PID) and other spinal lesions. Uncommon causes like nerve root schwannoma are rarely considered in the differential diagnosis of sciatica. Spinal schwannomas occur both sporadically and in association with neurofibromatosis type 1 (NF1; von Recklinghausen's disease). This case report describes lumbar foraminal schwannoma as an unusual cause of radiculopathy, presenting clinically as a lumbar disc prolapse. The diagnosis was confirmed on MRI scan. Patient had complete symptomatic recovery following surgical enucleation of the tumour mass from the L5 nerve root. This case report is of particular interest as it highlights the diagnostic confusion, which is bound to arise, because the clinical presentation closely mimics a lumbar PID. This often leads to delay in diagnosis and “failure of conservative treatment.”

We report a case of a 61 year old man who had a history of 4 years right leg pain. Clinical and radiological examination and MRI revealed a soft tissue mass in the popliteal fossa. A neurilemoma of the tibial nerve was confirmed after removal of the tumor and histological examination. To our knowledge this is the first case of a neurilemoma located in the tibial nerve reported in the literature. Tibial neFve R~sum~. Nous rapportons le cas d'un homme de 61 ans, souffrant d'une dou-Ieur g~ la jambe droite depuis 4 ans. L'examen clinique, radiologique et I'IRM revOlent une masse de tissus mous au niveau du creux poplitd. AprOs rdsection de la tumeur et 6rude histologique un neurinome du nerf sciatique poplitd interne est diagnostiqud. A notre connaissance c' est le premier cas publid d'un neurinome localisd gt ce niveau.
