Kluver-Bucy syndrome is defined as a rare neurobehavioral disorder with hyperphagia, hyperorality, hypersexuality, and visual agnosia. This syndrome is usually resulting from bilateral lesions of the anterior temporal lobe including amygdala. Although it could occur after various diseases, stroke is uncommon etiology. We report a patient with Kluver-Bucy syndrome due to bilateral posterior cerebral artery territory infarction.

Cerebral achromatopsia, which refers to a loss of color vision, is a rare complication of posterior circulation stroke. We report two patients who presented with achromatopsia and dyschromatopsia (incomplete form of achromatopsia) respectively after acute posterior cerebral artery infarction. Lingual and fusiform gyri within the occipito-temporal area are known to be responsible for color perception.

Spontaneous opening and closing of both eyes usually occurs in the normal awake state, unless a deliberate and voluntary attempt is made to open only one eye. We present a rare case of a male patient who was unable to open both eyes simultaneously after bilateral posterior cerebral artery infarction. He was able to close both eyes voluntarily. However, he was unable to keep both eyes open simultaneously and either the right or left eye remained closed. Upon a verbal command to open both eyes, the opened eye closed and the contralateral eye opened. When the closed eye was forced open, the opened eye closed. We thus presented a case of right-left dissociation of voluntary eyelid opening following bilateral posterior cerebral artery infarction, which was treated with botulinum toxin type A injection. Differential diagnosis to other movement disorders of the eyelids was discussed.

"Mirror-writing" is the simultaneous process of reversing individual letters and composing word strings in reverse direction. It is reported that the lesions which cause "mirror-writing" are left parietal lobe, left basal ganglia, right supplementary motor area, left supplementary motor area, left cingulate gyrus, and left angular gyrus. To explain this phenomenon, several theories have been proposed such as the motor, the visual dominance, the supplementary motor area, the visio-spatial, the visual word- form, the hemisaptial factor or directional and the reflected graphemic representation hypotheses. With reviewing some of literatures, we present a case of "mirror- writing" of posterior corpus callosum lesion which is not included in the aforementioned those.

Patients with hereditary hemorrhagic telangiectasia (HHT) are at risk of developing pulmonary arteriovenous malformations (pAVMs). Paradoxical embolism may occur through pAVMs or patent foramen ovale (PFO) and lead to cerebral infarction. We present a case of cerebral infarction with both pAVM associated with HHT and PFO. Evidence of a right-to-left shunt can suggest other treatment options for stroke prevention, and patients without evidence of conventional stroke etiologies require a thorough evaluation.
