OBJECTIVE: To present the imaging findings for two cases of intramedullary schwannoma involving the thoracic cord and the conus medullaris. PATIENTS AND METHODS: a 34-year-old man and a 53-year-old woman presented with symptoms of weakness and pain in the lower limbs. Myelography and magnetic resonance imaging as well as other examinations, were performed. RESULTS: The imaging failed to indicate the correct diagnosis in either patient. However, intramedullary schwannoma was confirmed pathologically in both patients. Subtotal excision resulted in local tumour recurrence at 5 and 3 years, respectively. CONCLUSIONS: Intramedullary schwannoma should be considered in the differential diagnosis of spinal cord tumours. The importance of accurate diagnosis from frozen sections at surgical biopsy is emphasized .
