Kyphoplasty is a minimally invasive spine surgical procedure performed to stabilize and treat the pain caused by a spine compression fracture. Complications are rare with kyphoplasty and include cement extrusion into the vertebral canal leading to spinal cord or nerve root compression. Herein, the authors present a case of a 72-year-old woman who presented with symptoms of a right L2 radiculopathy after a kyphoplasty procedure. ⋯ A transforaminal endoscopic surgical approach was used to remove the cement and decompress the L2 nerve. The patient's postoperative clinical course was uneventful. Clinicians should be aware that for the treatment of complications to vertebroplasty and kyphoplasty procedures, minimally invasive transforaminal endoscopic surgery is one option to avoid the destabilizing effects of laminectomy and facetectomy.

Case Reports
Prolactin-Secreting Pituitary Carcinoma with Dural Metastasis: Diagnosis, Treatment, and Future Directions.
Pituitary carcinoma is extremely rare, representing approximately 0.2% of all surgically resected pituitary neoplasms. It is thought to arise from World Health Organization grade II (atypical) pituitary adenomas. Pituitary carcinoma is defined by metastasis; it is otherwise indistinguishable from atypical pituitary adenomas, which can be considered carcinoma in situ. Pituitary carcinoma is difficult to diagnose and treat and is associated with poor long-term outcomes. ⋯ Long-term surveillance using serum prolactin as a tumor biomarker and correlation to imaging studies were critical for the diagnosis and interval screening for recurrence. This technique can be applied to all secretory atypical pituitary adenomas to improve early detection of potential metastasis. Further research, especially of genetic and epigenetic characteristics, could readily improve the diagnosis and treatment of pituitary carcinomas.

Review Case Reports
Fulminant vasculitis associated with extracranial dissections and occlusion, ischemic strokes, and aneurysm rupture: Case report and review of the literature.
Central nervous system vasculitis has multiple presentations, including stroke, seizures, cranial nerve palsies, and encephalopathy. ⋯ Fulminant central nervous system vasculitis can occur with critical vascular anomalies that require emergent intervention and should be part of the differential diagnosis of patients presenting with these multiple vascular pathologies.

Review Case Reports
Syringomyelia caused by traumatic intracranial hypotension: a case report and literature review.
Syringomyelia due to intracranial hypotension is rarely described. As a consequence, intracranial hypotension is less recognized as a potential cause of syringomyelia or mistaken with Chiari type 1 malformation. The pathogeny is poorly understood, and we lack diagnostic and therapeutic strategies for this particular setting. ⋯ Syringomyelia can be a consequence of long-term progression of intracranial hypotension, which must be differentiated from Chiari type 1 malformation. In our case, resolution was achieved by detecting and closing the CSF leak causing the intracranial hypotension. Reports of similar cases are necessary to understand the origin of CSF leak in traumatic intracranial hypotension and assess the best therapeutic strategy.
