Cubital tunnel syndrome (CuTS) is a prevalent but often under-recognized compressive neuropathy of the upper extremities, involving the entrapment of the ulnar nerve within the cubital tunnel at the elbow. CuTS is common, but remains relatively unfamiliar to many neurosurgeons c...
Objective: This study investigated the relationship between intraoperative motor evoked potential (MEP) improvement after decompression surgery for cervical compressive myelopathy (CCM) and postoperative neurological outcomes, and preoperative factors influencing MEP improvement...
Objective: Multilevel posterior cervical fusion (PCF) and decompression surgery is a viable treatment option for multilevel ossification of posterior longitudinal ligament (OPLL) and spondylotic myelopathy. Since OPLL is known to affect bone formation, this study aimed to examin...
Objective: Osteoporosis is highly prevalent among older adults and women. This condition leads to a deterioration in bone mineral density and microarchitecture, significantly increasing the risk of fractures. Additionally, osteoporosis commonly results in complications such as s...
Objective: Decompression with instrumented fusion is a common approach for treating spinal metastatic disease. However, in many cases, poor bone quality and compromised general condition increase the likelihood of mechanical failure and other complications. This study investigat...
Intraneural ganglion cysts (IGCs) are benign mucinous cysts within the epineurium of peripheral nerves. Hip joint-related IGCs are much rarer than those that arise from peripheral nerves around the joints of limbs. The unifying articular synovial theory has been accepted as expl...
Herpes zoster (HZ) involving the upper cervical nerves (C2-C4), which innervate the posterior head, is rare. There have also been few reports of HZ lesions involving the greater occipital nerve (GON), which refers to the medial branch of the dorsal ramus of the second cervical n...
The most common extradural spinal lesions are metastatic tumors. However, approximately 2.5% to 3.5% of spinal meningiomas are extradural meningiomas. This article describes a rare case of a thoracic extradural meningioma. A 58-year-old woman was admitted following two months of...
Objective: Cerebral aneurysms larger than 7 mm are considered at risk for rupture. The International Study of Unruptured Intracranial Aneurysms (ISUIA)-1 (1998) and ISUIA-2 (2003) suggested that there is a negligible risk of subarachnoid hemorrhage (SAH) in aneurysms larger than...
Melorheostosis is a rare type of sclerosing bone dysplasia with an incidence of approximately 0.9 per million individuals. This disease predominantly affects the appendicular skeleton, with rare involvement of the axial skeleton. Patients with spinal melorheostosis may present w...
Meningioma is one of the most common types of benign primary brain tumors in older adults, and multiple meningiomas are reported in fewer than 1% to 10% of cases. However, there is no definitive treatment guideline for patients with multiple meningiomas. An 80-year-old man prese...
Spinal extradural arachnoid cysts (SEACs) are exceptionally rare and require advanced imaging for an accurate diagnosis and surgical planning. Magnetic resonance imaging and computed tomography myelography play a pivotal role in delineating cyst characteristics and guiding effec...
Cervical rib (CR) refers to congenital bone growth in the seventh cervical bone, which can cause thoracic outlet syndrome (TOS). Since TOS has various etiologies, physical and radiological examinations are necessary for a proper diagnosis. We report a case of an 18-year-old fema...
Epithelioid hemangioendothelioma (EHE) is a rare benign vascular tumor, affecting fewer than one in a million individuals. Spinal EHE is exceptionally rare. This case report presents a case of recurrent spinal EHE, focusing on its clinical manifestation and providing a brief ove...
