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.

Case Reports Observational Study
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.
