A 27-year-old woman visited Kanto Teishin Hospital complaining of fever and petechiae in September, 1992. Her fetus had suddenly died in the uterus two weeks before (in the sixth month of pregnancy). Total white blood cell (WBC) count was 3.2 x 10(3)/microliters with 80% promyelocytes. Bone marrow was hypercellular with 90% promyelocytes. Disseminated intravascular coagulation (DIC) was recognized. She was diagnosed as having acute promyelocytic leukemia (APL), and treatment with daily oral administration of all-trans retinoic acid (ATRA) (70 mg/body/day) was begun. On day 4, hemiplegia and aphasia appeared. Broad cerebral infarction was suspected from computed tomography. On day 9, the WBC count increased rapidly, standard chemotherapy was added and she achieved complete remission. ATRA is known to have stimulatory effects on the differentiation of APL cells, but some reports have described thromboembolic events during the administration of ATRA. In this case, ATRA might have affected coagulability resulting in cerebral infarction.

We report a case of thrombotic thrombocytopenic purpura (TTP) with uncommon imaging features, namely concomitant small- and large-vessel thrombosis, atypical locations of posterior reversible encephalopathy syndrome (PRES) and microbleeds. A 58-year-old Chinese woman presented with slurred speech and multiple petechiae over lower limbs. Blood tests showed thrombocytopenia. Neuroimaging showed multiple acute small infarcts and PRES in the subcortical white matter, basal ganglia, thalamus, brainstem and occipital lobe. Microbleeds were noted. She was treated as TTP with infusion of cryo-reduced plasma (CRP). Patient subsequently developed dense right hemiplegia. Computed tomography of brain demonstrated a new major left middle cerebral artery territory infarct. She was stabilized after 2 weeks of treatment with daily CRP infusion, then received rehabilitation for major stroke. Early recognition of TTP provides the best chance of recovery as most lesions are reversible when TTP was treated. However, concurrent large artery thrombosis could cause major morbidity and mortality.
