@entity11924 ( @entity11924 ) is one of the histopathological hallmarks of @entity463 ( @entity463 ). In this study angiogenic potential in @entity463 was analysed according to the morphology of @entity11924 and by assessment of vascular density. The analysis of relations of vascular parameters to chosen clinical features was performed. Tissue samples from 46 @entity463 cases were examined. The clinical data included: @entity1 ' age (32-78 years), gender (17 @entity1 , 29 @entity1 ), location (frontal lobe--13, temporal--18, parietal--14, two lobes--1) and @entity5 size in CT (2-9 cm). Tumour vascularisation was analysed morphologically and quantitatively. Histologically two types of @entity11924 were distinguished: simple and glomeruloid. In vascular hot spots vessel density was assessed on sections immunostained for @entity2881 . @entity1538 was found in all cases. Glomeruloid proliferation was found in 33 cases with mean age of @entity1 59.5 yrs, while in the group without glomeruloids mean age was 48 yrs (statistically significant difference, p < 0.01). Mean vascular density value in examined @entity463 was 150.4 vessels/mm2 (median 141.5; SD--56.4) and younger age was related to higher vascular density (correlation coefficient R = -0.35; p = 0.017). Vascular parameters were related only to the @entity1 ' age among the analysed clinical data. The presented results show that morphologically microvascular proliferation is more intense in older @entity463 @entity1 , since higher vascular density is related to younger age. This observation may suggest the diversity of @entity463 angiogenic potential depending on @entity1 ' age.
