Multiple Myeloma With Intracranial And Spinal Intradural Metastasis: A Case Report, Der-Cherng Chen, Wei-Lin Hsu

BioMedicine

Multiple myeloma is a hematopoietic cancer that is multicentric and most commonly involves the spine. Multiple myeloma with extraosseous and intradural involvement is an extremely rare condition. Here we present a rare case of spinal multiple myeloma with intracranial and spinal intradural metastasis causing lumbar spinal nerve compression. We present a 60-year-old woman with progressive weakness of the lower limbs for several weeks. Spinal magnetic resonance imaging (MRI) showed a leptomeningeal tumor with nodularity spreading within the cauda equina. Examination of the brain using MRI showed a lytic skull bone lesion and leptomeningeal enhancement. The patient underwent L3-5 laminectomy. Immunohistological …

Incidence Of Pedicle Breach Following Open And Minimally Invasive Spinal Instrumentation: A Postoperative Ct Analysis Of 513 Pedicle Screws Applied Under Fluoroscopic Guidance, Xue Ling Chong, Aravind Kumar, Eugene Wei Ren Yang, Arun-Kumar Kaliya-Perumal, Jacob Yoong-Leong Oh

BioMedicine

Background: Even though pedicle screw application is a common procedure, and in-spite of spine surgeons being proficient with the technique, mal-positioning of pedicle screws can still occur. We intend to determine by postoperative CT analysis, the incidence of pedicle screw breach in the thoracolumbar spine despite satisfactory intraoperative placement confirmed by fluoroscopy.

Materials and Methods: Consecutive patients diagnosed with thoracolumbar fractures who underwent open or minimally invasive posterior stabilization under fluoroscopic guidance were retrospectively reviewed. Postoperative CT scans of patients were analysed to determine the incidence of pedicle breach despite satisfactory intraoperative placement, and also to determine the factors that …
