Case 34

 We present a rare case with brain damage of limbic system. MRI showed hemorrhage at cingulate gyrus of a main component of limbic system. The vascular disorders of limbic system are quite rare. A case of this week will be discussed about why limbic system is not predisposed to ischemic damage. As background knowledge, let us confirm blood supplies for limbic system.

Which combination is correct on blood supply for each component of limbic system?

a. Thalamus----- posterior cerebral artery

b. Cinglate gyrus -------Anterior cerebral artery +Posterior cerebral artery

c. Amygdala-----Anterior choroidal artery + Posterior choroidal artery

d. Parahippocampal gyrus----Carotid artery + Middle cerebral artery + Posterior cerebral artery

e. Hippocampus--------Posterior cerebral artery + Anterior choroidal artery

1.a, b, c   2. b, c, d   3. c ,d, e   4. all
