Intradural epidermoid tumors of the spinal cord are commonly associated with spinal cord dysraphism or invasive procedures. We report the particular relationships between spinal subarachnoid compartments and thoracic intradural-extramedullary epidermoid tumor, highlighting the relevant anatomic changes that may influence microsurgery. ⋯ A thorough knowledge of spinal subarachnoid space anatomy is helpful to distinguish between tumor membranes and arachnoidal planes and to achieve a safe and complete resection to avoid recurrences.

Supratentorial arteriovenous malformations (AVMs) are heterogeneous pathologic entities and require an intricate decision-making process for their management. We present 3 cases of supratentorial arteriovenous malformations with diverse clinical presentations and highlight the role of microsurgical resection in present-day multimodality treatments of arteriovenous malformations.

To review the complex pathogenesis of the subdural membrane and the link between head trauma, dementia, and dural lymphatics. ⋯ Further research into the possible link between traumatic brain injury and cSDH in particular and dural lymphatics and intracranial fluid dynamics is warranted.

Review Case Reports
Long-term patency of posterior auricular artery-middle cerebral artery bypass for adult-onset moyamoya disease: case report and review of literature.
Direct extracranial-intracranial (EC-IC) bypass is one of the fundamental techniques to prevent recurrent stroke in patients with adult-onset ischemic moyamoya disease. When the standard superficial temporal artery (STA) cannot be used for a graft, the posterior auricular artery (PAA) can be a potential surrogate graft. ⋯ In conclusion, the PAA becomes a potential donor for EC-IC bypass as long as its diameter is approximately 1.0 mm. Even though the PAA-MCA bypass is not primarily considered in the initial revascularization, it can be useful as a combination bypass with other grafts or as a rescue for recurrent ischemia.

Review Case Reports
Non-traumatic multiple vertebral compression fractures induced by primary hyperparathyroidism: A case report and literature review.
Primary hyperparathyroidism (PHPT) is one of the causes of osteoporosis and is known to increase the fracture risk of bone. However, multiple vertebral compression fracture because of PHPT is extremely rare. ⋯ When a patient has multiple compression fractures without any trauma history and a very low T score, the presence of other underlying diseases should be investigated.
