Case Reports
Retropharyngeal granulation: A delayed complication of anterior cervical discectomy and fusion in C2-3.
A 26-year-old man presented with acute quadriparesis owing to a traffic accident. A computed tomography scan revealed a hangman fracture and locking of the left facet joint at C2-3. Magnetic resonance imaging showed a high signal change of the spinal cord on T2-weighted image and hemorrhage in the C2-3 level. ⋯ Retropharyngeal granulation can occur as a late complication associated with plate fixation after anterior cervical diskectomy and fusion. Recurrent retropharyngeal wall granulation caused by plate irritation might only be resolved after plate and screw removal.

To study improvements in outcomes after surgery for intracranial meningiomas. ⋯ Meningioma surgery as well as patient population changed over the 2 decades considered in this study. We observed higher rates of gross total resection in the later period and the perioperative outcomes improved or were unchanged, which signifies better long-term outcomes, RFS, and OS.

Previous studies of percutaneous endoscopic lumbar discectomy (PELD) to treat lumbar disc herniation (LDH) have shown good clinical results. However, limited information has been reported regarding postoperative improvement in back muscle function. We aimed to determine whether changes in neuromuscular patterns, assessed using the flexion-relaxation phenomenon (FRP), could be observed after PELD. ⋯ PELD for individuals with LDH appears to normalize paraspinal muscle activation during lumbar flexion-extension movement. The gross range of motion and disability-related limitations of physical activity also improved.

We describe a patient affected by a T-cell primary central nervous system lymphoma (PCNSL) with highly aberrant specific B-cell markers (CD79a and CD20). An unusual imaging presentation leads us to misdiagnose this lesion for a meningioma and perform surgical resection. ⋯ Furthermore, this case calls attention to the complexity of lineage assignment, imaging diagnosis, and treatment strategy in PCNSL.

To compare the observation of high-grade glioma (HGG) based on intraoperative multiplane ultrasonography (US) images and preoperative reconstructive coplanar T1-weighted enhanced magnetic resonance imaging (MRI) using volume navigation (V Nav) fusion image technology. ⋯ The V Nav fusion image system combining intraoperative real-time US imaging with reconstructive preoperative coplanar MRI is valuable for image-guided HGG resection. It is suitable for neurosurgeons who lack the expertise in US technology to discern the brain structure and allows better recognition of tumor and edema tissues compared with reconstructive preoperative coplanar-enhanced MRI in real time and in multiplane from different angles. In addition, CEUS combined with B-mode US could improve tumor detection and resection control in neurosurgery, even in single US-guided operations.
