We herein report a 15-year-old girl who developed rapid progressive muscle weakness soon after the third injection of a bivalent human papilloma virus (HPV) vaccine. Although immunotherapies were performed for possible vaccine-related disorders, she died of respiratory failure 14 months after the onset of the disease. A genetic analysis identified a heterozygous p.P525L mutation of the fused in sarcoma (FUS) gene, and a histopathological analysis was also consistent with FUS-associated amyotrophic lateral sclerosis (ALS) without any evidence of neuroinflammation. We concluded the diagnosis to be FUS-ALS, although we cannot completely rule out the possibility that the vaccination worked as a trigger.

Cerebral microbleeds (CMBs) usually produce no symptoms. We encountered a patient who developed cognitive decline and psychotic symptoms associated with nonconvulsive status epilepticus (NCSE), with presumptive epileptogenic focus possibly caused by a CMB. A 70-year-old man developed progressive cognitive disturbances including disorientation and hallucinations two months after a mild head injury. He was admitted to our hospital three months after the trauma, because of progression of symptoms. The first positron emission tomography (PET) with [18F]fluoro-2-deoxy-d-glucose (FDG) demonstrated intense FDG uptake in the left occipitoparietal region, in which a CMB was detected by T2∗-weighted magnetic resonance imaging (MRI). Electroencephalography showed continuous slow waves in the left occipital and parietal areas. After anticonvulsive therapy, his symptoms completely disappeared, accompanied by change in FDG uptake. Our case suggests that CMBs may be an epileptogenic focus of NCSE, and that FDG-PET is useful for the diagnosis of NCSE and assessment of therapeutic efficacy.

Purpose: To compare reliability and elucidate clinical application of magnetization-prepared rapid gradient-echo (MPRAGE) with 9-fold acceleration by using wave-controlled aliasing in parallel imaging (Wave-CAIPI 3 × 3) in comparison to conventional MPRAGE accelerated by using generalized autocalibrating partially parallel acquisition (GRAPPA) 2 × 1.Methods: A total of 26 healthy volunteers and 33 patients were included in this study. Subjects were scanned with two MPRAGEs, GRAPPA 2 × 1 and Wave-CAIPI 3 × 3 acquired in 5 min 21 s and 1 min 42 s, respectively, on a 3T MR scanner. Healthy volunteers underwent additional two MPRAGEs (CAIPI 3 × 3 and GRAPPA 3 × 3). The image quality of the four MPRAGEs was visually evaluated with a 5-point scale in healthy volunteers, and the SNR of four MPRAGEs was also calculated by measuring the phantom 10 times with each MPRAGE. Based on the results of the visual evaluation, voxel-based morphometry (VBM) analyses, including subfield analysis, were performed only for GRAPPA 2 × 1 and Wave-CAIPI 3 × 3. Correlation of segmentation results between GRAPPA 2 × 1 and Wave-CAIPI 3 × 3 was assessed.Results: In visual evaluations, scores for MPRAGE GRAPPA 2 × 1 (mean rank: 4.00) were significantly better than those for Wave-CAIPI 3 × 3 (mean rank: 3.00), CAIPI 3 × 3 (mean rank: 1.83), and GRAPPA 3 × 3 (mean rank: 1.17), and scores for Wave-CAIPI 3×3 were significantly better than those for CAIPI 3 × 3 and GRAPPA 3 × 3. Image noise was evident at the center for additional MPRAGE CAIPI 3 × 3 and GRAPPA 3 × 3. The correlation of segmentation results between GRAPPA 2 × 1 and Wave-CAIPI 3 × 3 was higher than 0.85 in all VOIs except globus pallidus. Subfield analysis of hippocampus also showed a high correlation between GRAPPA 2 × 1 and Wave-CAIPI 3 × 3.Conclusion: MPRAGE Wave-CAIPI 3 × 3 shows relatively better contrast, despite of its short scan time of 1 min 42 s. The volumes derived from automated segmentation of MPRAGE Wave-CAIPI are considered to be reliable measures.

Primary central nervous system lymphoma (PCNSL) and chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) can share clinical features and may be indistinguishable, even after brain biopsy. We encountered a case of Epstein-Barr virus-positive (EBV+) PCNSL recurrence in a patient with clinical features of CLIPPERS, and repeat brain biopsy was required to reach the correct diagnosis. Four years after the initial diagnosis and treatment of PCNSL, "peppering" punctate enhanced lesions with transient steroid responsiveness were detected during brain magnetic resonance imaging (MRI). A second brain biopsy supported a diagnosis of CLIPPERS, while a third biopsy confirmed the diagnosis of recurrent PCNSL.
