We herein report a 47-year-old man with autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) revealed by periventricular radial linear enhancement on repeated brain magnetic resonance imaging (MRI). He presented with a history of headache and a fever followed by somnolence and worsening of consciousness. ⋯ At 30 days from the onset, repeated brain MRI revealed characteristic findings of GFAP-A, and we detected anti-GFAP antibodies in the CSF. Thus, repeated brain MRI provides clues for the diagnosis of GFAP-A.

A 59-year-old man undergoing hemodialysis was administered levetiracetam, after which he developed a systemic rash, high fever, severe liver dysfunction, and leukocytopenia with reactivation of human herpes virus 6. Atypical drug-induced hypersensitivity (DIHS) was diagnosed, and prednisolone was administered at 60 mg/day. ⋯ Despite the rarity of DIHS with concomitant fulminant liver failure from levetiracetam and sufficient clearance thereof by hemodialysis, our case suggests that this syndrome may still ensue, resulting in mortality, even in hemodialysis patients. Although no treatment has yet been established, strict monitoring and aggressive treatment may be required.

Liver Biopsy-confirmed Primary Hepatic Amyloidosis with Only Jaundice as the Initial Symptom: An Autopsy Case Report.
Amyloidosis causes various symptoms in many organs of the body, but amyloidosis that presents with liver damage alone has never been reported. We treated an 83-year-old man with amyloidosis who presented with liver damage alone. ⋯ The administration of bortezomib and dexamethasone was not effective, so he rapidly died of liver failure. An aggressive liver biopsy should be considered when unexplained jaundice is observed.

The patient was a 34-year-old woman who suddenly collapsed. On arrival, she was in cardiac arrest. Cardiac ultrasound revealed cardiac tamponade; thus, urgent thoracotomy with pericardiotomy was performed. ⋯ There were no signs of cardiac rupture, myocardial infarction or aortic dissection. We reported the first case of fatal bloody cardiac tamponade due to pericardial IMT in an adult. An autopsy is important for clarifying the etiology in cases of fatal cardiac tamponade of unknown cause.

Case Reports
Loss of Taste as an Initial Symptom of a "Facial Diplegia and Paresthesia" Variant of Guillain-Barré Syndrome.
Loss of taste is a relatively common symptom of coronavirus disease 2019 (COVID-19) and has also been considered a rare Guillain-Barré syndrome (GBS) symptom. We herein report a case of a facial diplegia and paresthesia (FDP) variant of GBS that initially presented as a loss of taste occurring two weeks after COVID-19 mRNA vaccination. The patient recovered completely after intravenous immunoglobulin therapy. Clinicians should consider the possibility of post-vaccination FDP manifesting as facial palsy and should be aware that GBS, including the FDP variant, can initially present as an isolated loss of taste.
