Schwannomas are common, benign, slow growing tumours of peripheral nerve sheath arising from the schwann cells of the neuroectoderm. They do not transverse the nerve but remain within the sheath on top of the nerve. They rarely present in the sciatic nerve. Sciatic schwannomas may mimic symptoms of herniated disc, usually with radiation of pain to buttocks and thigh region with inability to walk for long distances and sometimes may present with claudication. In the absence of low back pain and with a normal Lumbo-Sacral MRI study, causes intrinsic to sciatic nerve needs to be thought off, which often delays the diagnosis. Rarity in our case-patient presented with tingling sensation and inability to squat on hard surface for more than 10 minutes with a normal x-ray and MRI study of lumbosacral spine.
