Intramedullary astrocytoma is one of the less common tumours of the central nervous system. Certain ambiguities in the literature led us to make a retrospective review of a series of our own (2003–2009) and to compare the results with available literature. This series comprised 15 patients (10 women, 5 men), mean age 42.6 years. According to the McCormick scale, 5 patients were class I, 4 class II, 1 class III and 5 class IV. No tumour was radically resected, while 11 patients underwent subtotal resection, 4 only bio­psy. Morbidity/mortality was 20% (1 dead and 2 patients deteriorating on the McCormick scale). Thirteen tumours were classified as low‑grade, 1 as grade III and one as glioblastoma. During the follow‑up period (mean 29.3 months) 5 patients died, 4 due to tumour progression. Median overall survival was estimated at 35.8 months. Younger age (p = 0.03), male sex (p = 0.04) and the presence of tumour cyst (p = 0.01) were identified as positive prognostic factors influencing overall survival. Other prognostic factors from the literature are discussed and treatment recommendations are made on the basis of its reviewing.

Key words:
