Fig 1.
Diagrammatic representation of TSV types I and II containing venous angle and false venous angle, respectively.
(ICV, internal cerebral vein; ASV, anterior septal vein; TSV, thalamostriate vein; FM, Foramen of Monro).
Fig 2.
Diagram representingtwo different types of ACV.
Type 1 contains 1 trunk; Type 2 contains 2 trunks. (ICV,internal cerebral vein; ASV,anterior septal vein; TSV, thalamostriate vein; ACV, anterior caudate vein).
Fig 3.
Diagram representingthree different types of ACV.
Type A, joining the TSV; Type B, joining the ASV; Type C, joining the angle of TSV and ASV (ICV,internal cerebral vein; ASV,anterior septal vein; TSV, thalamostriate vein; ACV, anterior caudate vein).

a, transverse images; b, sigittal images; c and d, displaying the tiny deep medullary veins. (1,internal cerebral vein (ICV); 2,thalamostriate vein (TSV); 3, anterior septal vein (ASV); 4, anterior caudate vein (ACV); and 5,transverse caudate vein (TCV); the white arrowhead, small deep medullary veins).
