Gross examination of the canine brain with porencephaly and focal cerebellar vermis atrophy. (a) Brain: cerebral cleft in the left parietal and occipital lobes, creating a communication between the subarachnoid space and the left lateral ventricle. The dotted lines represent the point from where the sections destined to histopathology were taken. (b) Cerebellum: caudal view of the rhombencephalon exhibiting a focal atrophy in the caudal paravermal and vermal portions of the cerebellum (arrow). (c) Brain: transverse sections of the whole brain. Note the areas affected by the cleft (arrowhead) and also a thinning of the left hippocampal formation (*). Observe also a focal atrophy in the caudal paravermal and vermal portions of the cerebellum (arrow) bn: basal nuclei; c: cerebellum; cv: cerebellar vermis; fl: frontal lobe; h: hippocampal formation; lv: lateral ventricle; m: midbrain; mo: medulla oblongata; ol: occipital lobe; p: pons; pl: parietal lobe; sc: spinal cord; t: thalamus.
