“…Transiently restricted water diffusion in the corpus callosum has been reported in various conditions such as acute encephalopathy [2,3], delirious behavior [4], occasional seizures [5] and epilepsy [6]. However, there have been few reports on transiently restricted water diffusion in the corpus callosum in patients with bacterial infection including meningitis [7]. Here we report two infants with bacterial meningitis associated with restricted water diffusion in the corpus callosum.…”

“…There have been few reports on transient callosal lesion in bacterial infection. Hong and Joo [7] reported a 20-year-old man who had temporary encephalopathy and was diagnosed with septic metastasis of Staphylococcus au-reus involving lungs and multiple joints. Brain MRI of the patient revealed an isolated and transient splenial lesion of the corpus callosum.…”

Here we report two infants with bacterial meningitis associated with restricted water diffusion in the corpus callosum. Both patients were admitted because of pyrexia and not doing well. One patient had a seizure. Group B streptococcus was isolated form blood and cerebrospinal fluid of both patients. Diffusion-weighted images showed transiently restricted water diffusion in the corpus callosum in both patients without additional neuroimaging abnormalities. The outcome of the patients is presumed to be favorable. The magnetic resonance imaging findings of our patients will widen the spectrum of restricted water diffusion in the corpus callosum.

“…Patients with infection may be associated with hyponatremia. [29,31] When hyponatremia occurs, the osmotic pressure of the cells in the corpus callosum is decreased and the increased free water entered into the cells leading to cytotoxic edema eventually. [15] Tani et al [96] reviewed clinical date of 24 patients with RESLES and found that all of them had fever, suggesting that fever may be associated with RESLES.…”

Background:Reversible splenial lesion syndrome (RESLES) is a rare clinico-radiological disorder with unclear pathophysiology. Clinically, RESLES is defined as reversible isolated splenial lesions in the corpus callosum, which can be readily identified by magnetic resonance imaging (MRI) and usually resolve completely over a period of time. RESLES could be typically triggered by infection, antiepileptic drugs (AEDs), poisoning, etc. More factors are increasingly recognized.Methods and results:We reported herein an 18-year-old female patient with lobar pneumonia who developed mental abnormalities during hospitalization. An isolated splenial lesion in the corpus callosum was found by head MRI and the lesion disappeared 15 days later. Based on her clinical manifestations and radiological findings, she was diagnosed with lobar pneumonia associated RESLES. We further summarize the up-to-date knowledge about the etiology, possible pathogenesis, clinical manifestations, radiological features, treatment, and prognosis of RESLES.Conclusion:This report contributes to the clinical understanding of RESLES which may present with mental abnormalities after infection. The characteristic imaging of reversible isolated splenial lesions in the corpus callosum was confirmed in this report. The clinical manifestations and lesions on MRI could disappear naturally after 1 month without special treatment.

“…MERS is caused by various viruses, such as influenza, mumps, adenovirus, varicella, and zoster virus, but rarely by bacteria [ 7 , 9 ]. Thus far, only one case of MERS caused by S. aureus has been reported [ 10 ]. To the best of our knowledge, this is the first reported case of MERS with TSS.…”

“…Several viruses (influenza virus, adenovirus, mumps virus, varicella zoster virus [ 2 , 3 ], rotavirus [ 4 ], measles virus [ 5 ], and hepatitis A virus [ 6 ]) and bacteria ( Escherichia coli [ 7 ], Legionella pneumophila [ 8 ], and Mycoplasma pneumoniae [ 9 ]) have been reported to cause MERS, but bacteria are rarely the cause [ 2 , 3 ]. Staphylococcus aureus , especially, is a very rare cause of MERS, and only one such case has been reported so far [ 10 ]. Moreover, there are no reports on MERS associated with toxic shock syndrome (TSS).…”

Clinically mild encephalitis/encephalopathy with a reversible splenial lesion caused by methicillin-sensitive Staphylococcus aureus bacteremia with toxic shock syndrome: a case report

BackgroundClinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is a mild encephalopathy caused by various pathological processes, but encephalopathy due to bacteria is rare.Case presentationWe report the case of a 45-year-old Japanese woman who on receiving chemotherapy for advanced breast cancer developed an altered mental status and dysarthria soon after fever from infection of a subcutaneous implantable port. Staphylococcus aureus was detected in her blood cultures. Magnetic resonance imaging (MRI) revealed an ovoid lesion in the central portion of the splenium of the corpus callosum (SCC). Although hypotension was not observed, we diagnosed probable toxic shock syndrome (TSS) based on fever (temperature: >38.9 °C), altered mental status, erythema, desquamation, thrombocytopenia, liver dysfunction, and creatine phosphokinase elevation. We administered antimicrobial therapy and her neurological symptoms improved gradually. The lesion in the SCC completely disappeared on MRI 7 days after disease onset.ConclusionsWe diagnosed this case as MERS caused by S. aureus bacteremia with TSS. This is the first report of such a case, and we suggest that when a TSS patient presents with neurological symptoms, the possibility of MERS should be considered.
