Hyaline thrombus of vessel in centre of a punctate hæmorrhage. The thrombus was stained brown by dissolved pigment. Around the blocked vessel is a white area of brown substance containing numbers of leucocytes; outside this is the hæmorrhage, not very distinctly seen. The specimen was prepared from the subcortical white matter of the frontal lobe. (× 345.)
Leash of small perforating optostriate arteries filled with pigment granules. Two of the arterioles show miliary aneurisms. (× 350.)
Three punctate hæmorrhages showing optostriate arterioles filled with pigment granules. (× 30.)
