Spinal Epidural Lipomatosis Causing Lumbar Canal Stenosis: A Pictorial Essay on Radiological Grading and the Role of Bariatric Surgery Versus Laminectomy


Spinal epidural lipomatosis (SEL) is a rare condition characterized by an excessive accumulation of adipose tissue in the spinal canal that can have a compressive effect on intraspinal neuroanatomical structures, leading to clinical symptoms. Several different conservative and surgical treatment strategies have been proposed but the treatment and outcomes remain controversial. There is a lack of severity based evidence documenting the success of decompressive laminectomy in SEL and there are only anecdotal reports of clinico-radiological success with weight loss from bariatric surgery

Fourth‑generation bypass and fow reversal to treat a symptomatic giant dolichoectatic basilar trunk aneurysm


Background Giant dolichoectatic basilar trunk aneurysms have an unfavorable natural history and are associated with high morbidity, but their neurosurgical treatment is complex and challenging.
Methods Flow reversal reconstruction with fourth-generation bypass and proximal vertebral artery clip occlusion is performed via orbitozygomatic craniotomy with the Kawase approach under rapid ventricular pacing.
Conclusion Fourth-generation bypass is an innovative, technically challenging, and clinically efective tool in the treatment armamentarium for giant dolichoectatic basilar trunk aneurysms.

Management of Osteoporosis and Spinal Fractures: Contemporary Guidelines and Evolving Paradigms

Physicians involved in treating spine fractures secondary to osteopenia and osteoporosis should know the pathogenesis and current guidelines on managing the underlying diminished bone mineral density, as worldwide fracture prevention campaigns are trailing behind in meeting their goals. This is a narrative review exploring the various imaging and laboratory tests used to diagnose osteoporotic fractures and a comprehensive compilation of contemporary medical and surgical management. We have incorporated salient recommendations from the Endocrine Society, the American Association of Clinical Endocrinology (AACE), and the American Society for Bone and Mineral Research (ASBMR).

De Novo Glioblastoma Masqueraded within a Hemispheric Dural Meningiomatosis: Rare Imaging Findings and Rationale for Two-Staged Resection


Introduction Collision tumors present as histologically different juxtaposed neoplasms within the same anatomical region, independent of the adjacent cell population. De novo intracranial collision tumors involving metachronous primary brain neoplasms alongside dural meningiomatosis are not well documented in the literature
