Two Episodes of Transfusion-related Acute Lung Injury (TRALI) Occurring within a Short Period: A Case Report.
Transfusion-related acute lung injury (TRALI) is a non-hemolytic adverse reaction that occurs ≤6 hours after receiving a transfusion. A 72-year-old man with leukemia developed severe hypoxemia after platelet transfusions on two occasions within a 4-day period. ⋯ The pathogenesis of TRALI includes an antibody-mediated mechanism and a non-antibody-mediated mechanism, in which various factors combine to activate pulmonary neutrophils. In our case, it is considered that the patient's neutrophils reached the activation threshold for the development of TRALI after the accumulation of various factors besides anti-leukocyte antibodies.

Coronavirus Disease 2019 Complicated by Multiple Simultaneous Intracerebral Hemorrhages.
The relationship between coronavirus disease 2019 (COVID-19) and intracerebral hemorrhage remains unclear. We herein report a case of severe COVID-19 pneumonia complicated by multiple simultaneous intracerebral hemorrhages (MSICH). ⋯ Laboratory findings showed hypercoagulability, suggesting that thrombotic etiologies, such as sinus thrombosis or cerebral infarction, might also have caused MSICH. MSICH can occur as a fatal complication of COVID-19, and this should be considered when providing treatment.

Reversible Splenial Lesion Syndrome with Some Novel Causes and Clinical Manifestations.
Objective Reversible splenial lesion syndrome (RESLES) is a clinical radiological syndrome characterized by a reversible lesion of the splenium of the corpus callosum with a decreased apparent diffusion coefficient (ADC) value. The clinical manifestations of RESLES are diverse. Methods Fifteen cases of adult RESLES patients (10 males and 5 females) were retrospectively selected from the radiology system using the key word "corpus callosum" at a university-affiliated tertiary care hospital between May 1, 2015 and December 31, 2019. ⋯ Paroxysmal blurred vision may be a relatively specific symptom of RESLES. Levetiracetam, carbamazepine or valproate could be the cause of RESLES, exposure to the rabies vaccine could be another predisposing factors for RESLES as well. RESLES type 1 was therefore found to be highly "reversible" with an excellent prognosis.

A 51-year-old man developed a sudden headache during golf practice, followed by a high fever. He was admitted with suspected neutrophilic meningitis and was diagnosed with chemical meningitis caused by a dermoid cyst rupture based on the characteristic magnetic resonance imaging (MRI) findings, which showed multiple lipid droplets in his ventricle and cistern. ⋯ On MRI, the lipid droplets appeared to have migrated by gravity because of the body position. Therefore, the body position should be considered to prevent obstructive hydrocephalus by lipid droplets after a dermoid cyst rupture.

Objective To investigate the long-term efficacy and safety of magnetic resonance imaging-guided focused ultrasound (MRgFUS) unilateral ventral intermediate nucleus (Vim) thalamotomy for medication-refractory essential tremor (ET). Methods We performed MRgFUS left-sided Vim thalamotomy for 10 medication-refractory ET patients (8 men and 2 women, aged 67.1±17.5 years, all right-handed). We followed them for 2 years using the clinical rating scale for tremor (CRST) and the quality of life in essential tremor questionnaire (QUEST). ⋯ There were no delayed adverse events. Conclusion MRgFUS unilateral Vim thalamotomy could be adopted as one of the therapeutic options for intractable ET. Further improvement of tremor in the targeted hand or contralateral Vim thalamotomy may be necessary to improve the quality of life.
