Abstract: Sciatic nerve schwannoma is a rare disease, often misdiagnosed as sciatica in patients with no prolapsed disc in the lumbar spine and a negative straight leg raise test. MRI followed by biopsy is the investigation of choice. We present a case of a 45-year-old male with a 2-year-old history of right lower limb radiculopathy with 2 months old ACL tear. MRI revealed right sciatic nerve mass which was confirmed to be schwannoma on biopsy by FNAC. ACL reconstruction was done followed by schwannoma excision and sciatic nerve reconstruction by using cable nerve grafts. Post-operative histopathological examination reconfirmed Sciatic nerve Schwannoma. This case has been highlighted to highlight the unusual manifestations of sciatic nerve schwannoma to prevent its misdiagnosis and delayed treatment.
