It is variable in morphology, but the astroblastic pseudorosettes and vascular hyalinization are the most important features. Most astroblastomas occur in the cerebral hemisphere. We report a recurrent high-grade astroblastoma with MN1-BEND2 fusion in the spinal cord. Two lesions were found in the T5-7 level and T12-L1 level, and they were well defined in images. Rhabdoid and signet-ring-like cells were observed. It may be classified as a high-grade tumor due to cellularity, high mitotic count, and pleomorphism. The tumor cells were diffusely positive for GFAP, Olig-2, and S-100 protein. We found the MN1 arrangement and the loss of chromosome 1p by FISH, and further validated the BEN domain containing 2 genes (BEND2), which is the fusion partner of meningioma 1 gene (MN1), by next-generation sequencing (NGS) and Sanger sequencing. The MN1 mutation is crucial in the diagnosis and prognosis of rare astroblastoma. The spinal cord astroblastoma may have a high recurrence rate because of the residual lesion at the unique location and higher grade; the connection with the gene mutation is unclear. Regular follow-up is necessary. Further study and more cases are needed to establish evidence for diagnosis, prognosis, and treatment of astroblastoma with molecular characteristics.","PeriodicalId":55251,"journal":{"name":"Clinical Neuropathology","volume":"42 1","pages":"30-39"},"PeriodicalIF":1.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10751587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It arises from midline structures in the brain and spinal cord. Recently, the presence of H3 K27M mutation is described in most cases. Extra-cranial osseous metastasis is rarely encountered.Case presentation: We present an interesting case of DMG with bone metastasis at presentation in a 19-year-old male. In addition, a literature review on similar cases is presented.Discussion: DMG mostly affects children and young adults. It has a broad spectrum of phenotypes, shows diffuse growth pattern, midline location, and is frequently H3 K27M-mutant. Radiotherapy remains the mainstay of treatment that might improve overall survival. Metastasis outside the CNS remains a rare occurrence, especially at presentation, and constitute a diagnostic challenge.Conclusion: Bone is one of the most common sites for metastasis of primary CNS tumors, which would severely impact prognosis. Oncologists, radiologists, and pathologists should keep an index of suspicion when encountering bone metastasis in the presence of a CNS midline tumor, so that timely diagnosis and management can be rendered.","PeriodicalId":55251,"journal":{"name":"Clinical Neuropathology","volume":" ","pages":"263-270"},"PeriodicalIF":1.1,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40410286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aim to perform an electrodiagnostic, nerve imaging, and histological study of EGR2-associated neuropathy.Materials and methods: We performed a retrospective analysis of two patients with EGR2-related neurology at our hospital. The neuropathy was confirmed by the nerve conduction study. Nerve imaging and sural biopsies were performed in two patients.Results: Two unrelated boys exhibited early-onset length-dependent neuropathy. Next generation sequencing identified EGR2 gene with previously described E412K mutation in the third zine finger domain in patient 1 and a previously undescribed variant D355N mutation in the first zinc finger domain in patient 2. The magnetic resonance imaging of the lumbosacral plexus showed no abnormalities in patient 1 and thickened lumbosacral plexuses in patient 2. Electrophysiology and nerve biopsies showed a prominent axonal neuropathy, accompanied with demyelinating involvement.Conclusion: Therefore, it seemed that the EGR2 mutations could cause not only the known demyelinating type and axonal type but also mixed-type CMT. Our findings expanded the phenotypic heterogeneities of EGR2-associated neuropathy.","PeriodicalId":55251,"journal":{"name":"Clinical Neuropathology","volume":" ","pages":"245-252"},"PeriodicalIF":1.1,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40410284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We collected the clinical data of a patient with severe weakness of the lower limbs induced by repeated pregnancy and performed relevant experimental examinations, including neuromuscular electrophysiological examination, neuromuscular biopsy, and genetic testing. The patient reported weakness of the right lower extremity after delivery of the first child. Initially, the right foot was weak during lifting, and symptoms gradually progressed to weakness when landing on the toe during walking. She then developed weakness of the right lower extremity and thinning of the right leg. After an interval of 2.5 years, after delivery of the second child, her left lower extremity developed asthenia, with the same symptoms as previously reported for the right lower extremity. Subsequently, weakness of both lower extremities became progressively worse, and she developed difficulty sitting up, getting out of bed, and walking. Physical examination showed that both upper limb vertebral tracts were damaged and both lower extremity motor nerves were damaged. Electrophysiology suggested motor axonal neurogenic damage. Brain magnetic resonance imaging demonstrated leukodystrophy. Sural nerve biopsy suggested mild axonal damage. Skeletal muscle biopsy suggested neurogenic skeletal muscle damage. Genetic testing suggested that there was a heterozygous mutation at the shear site of the AARS gene. An AARS mutation may cause dHMN associated with pyramidal tract signs.","PeriodicalId":55251,"journal":{"name":"Clinical Neuropathology","volume":"41 6","pages":"271-276"},"PeriodicalIF":1.1,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10382664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
