Scientific BACKGROUND: Bilateral thalamic infarct is quite rare and encountered at the rate of 0.6%. Emboly from an artery to another, cardioembolism, migrain and the existence of an only perforing artery are among the causes of bilateral thalamic infarct. During the course of many hematologic diseases, tendency to thrombosis increases, and therefore, stroke can also be witnessed. OBJECTIVE: Upon scanning the literature, concurrence of myelodysplastic syndrome and bilateral thalamic infarct have not been encountered. Thus, a subject with myelodysplastic syndrome was aimed to be discussed due to the development of bilateral thalamic infarct in the light of the literature. CASE: A 52 years old women was consulted with the complaint of headache and weakness on her right side as an inpatient in hematology unit. On the neurological examination of the patient followed by hematology unit for a decade with the diagnosis of myelodysplastic syndrome, right hemiparesis including her face was determined. On the sensorial examination, there was a decrease in all her sensorial modalities on the right, but there was only loss of sensorial vibration on the left. On cranial MRI, bilateral thalamic infarct was detected. No other pathologies except for myelodysplastic syndrome were found in the etiology. CONCLUSION: It should also be remembered that a blood disease such as myelodysplastic syndrome could be among the causes of bilateral thalamic infarct
