Spinal low-grade ependymal tumors harboring telomerase reverse transcriptase promoter mutation and chromosome 7 gain with methylation profile of spinal subependymoma

Yoshitaka Nagashima, Junya Yamaguchi, Yusuke Nishimura, Masafumi Seki et autres

Spinal intramedullary tumors comprise a heterogeneous group of entities with diverse histopathological features, making their diagnosis particularly challenging. With the introduction of DNA methylation profiling, the underlying biological diversity of these tumors has been increasingly clarified and systematized; however, owing to the …

Unilateral laminotomy for bilateral decompression and balloon kyphoplasty to decompress lumber canal stenosis aggravated by osteoporotic vertebral compression fractures: A technical note

Yoshitaka Nagashima, Yusuke Nishimura, Motonori Ishii, Tomoya Nishii et autres

Background: The optimal treatment of lumbar canal stenosis (LCS) associated with osteoporotic vertebral fractures (OVFs) remains unclear. Here, we have combined a minimally invasive unilateral laminotomy for bilateral decompression (ULBD) alone with balloon kyphoplasty (BKP) for LCS aggravated by OVF. Methods: ULBD …
