It originates from Schwann cells which are involved in myelination of peripheral nerves and commonly occur in the soft tissues of the head and neck. Intraosseous schwannoma is rare and accounts for only 0.2% of overall primary bone tumours. Merely 200 cases have been reported in the literature. Intraosseous schwannoma of long bones is even rarer, amounting for only 20 cases reported. We present a case of intraosseous Schwannoma in the distal shaft of the fibula, in an 18-year-old female patient who presented with pain in the right leg for 2 years. MRI showed a lytic lesion, with a differential diagnosis of aneurysmal bone cyst. The tumour was excised and on histopathological examination, a diagnosis of intraosseous schwannoma was made.
