Abstract
We report the case of a 53-year-old male with a right Achilles tendinosis, who complains about a mild gait disorder starting after walking several kilometers. In the following months he develops neurological symptoms. MRI lumbar spine shows an intramedullary tumor at level Th12. A biopsy confirms the diagnosis of an intramedullary astrocytoma. Primary intramedullary tumors are relatively rare. Clinical presentation is often insidious. The authors want to make a point to reconsider a diagnosis in case it does not explain completely the anamnestic or clinical findings. According to the literature there is no optimal approach to the management of these tumors.
