Two cases of parasitic embolism of the cerebral arteries in the dog causedby Dirofilaria immitis were recorded by Olson (1970) and Patton and Garner (1970) inthe United States. No such cases had been reported in Japan where canine heart wormdisease is enzootic most prominently in the world. Recently, the authors had an oppor-tunity of examining three dogs with the cerebral arteries affected with D. immitis em-bolism, showing such sudden nervous signs as unstable gait, circling, tumble, roaring,visual disorders, disturbed swallowing, cloudiness of consciousness and coma. The resultsof pathological examination of these dogs are summarized as follows.l. In each dog, severe obstruction was established in the cerebral arteries by a singleworm of D. immitis. The parasite was so large and long in size that it filled the vesselalmost completely, extending from the left middle cerebral artery to the left posteriorcommunicating artery and the left posterior cerebral artery in dog No. 1, from the leftanterior cerebral artery to the left middle cerebral artery in dog No. 2, and from the leftposterior cerebral artery to the cerebral arterial circle and the basilar artery in dog No. 3(Fig. l).2. In each case, the size and severity of cerebral infarct corresponded generally to thedistribution of arteries occluded by v. immitis, as shown in rigs. 2 to 4; that is, theaffected areas of the cerebrum were the left temporal and occipital lobes in dog No. 1,the left frontal, parietal and temporal Robes in dog No. 2, and almost all the lobes ofthe right hemisphere and the left-side portions of the thalamus and hippocampus in dogNo. 3. It was confirmed microscopically that these affected cerebral areas were stillrecognized in the early stage of encepholomalacia.3. Worms recovered from the cerebral arteries of the three dogs were morphologicallyidentified as adult forms of D. immitis.
