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.

Distal outflow occlusion and extracranial-intracranial bypass represent a possible option for the surgical management of complex middle cerebral artery (MCA) aneurysm. A limitation of the distal clipping strategy combined to bypass is related to the difficulties in predicting intraoperatively the good blood flow supply to the brain territory distal to the aneurysm and the extent and speed of aneurysmal thrombosis. ⋯ We present the first report of a synergistic intraoperative utilization of ICG-VA and CEUS in studying parenchymal perfusion and aneurysm flow in complex neurovascular procedures.

Hemimasticatory spasm (HMS) is a rare masticatory muscle disorder. Drug therapy, microvascular decompression, and botulinum toxin have had varying efficacy and adverse effects. We have reported the cases of 2 patients who had undergone a novel therapy for HMS, based on endoscope-assisted nerve avulsion of the masseter nerve attached to the temporomandibular joint (TMJ) disc. ⋯ Endoscope-assisted avulsion of the masseter nerve attached to the TMJ disc showed a good curative effect, little trauma, few complications, and a quick postoperative recovery. It could be used as an alternative treatment of HMS for selected patients.

Three-dimensional (3D), high-definition (HD) endoscopy has been recently introduced in neurosurgery, and its value has been discussed extensively in endonasal skull base surgery. Because there has been no reported clinical series on the use of a recent 3D-HD ventriculoscope, the aim of this study was to describe our initial experience with this novel device. ⋯ 3D-HD technology seems to provide potential advantages in ventricular surgery. This initial experience is promising but must be confirmed by larger series.

Contralateral C7 nerve transfer is widely applied for the treatment of brachial plexus injuries or central paralysis of the upper extremities. The surgical approach has evolved from the precervical subcutaneous route to the prespinal route, which is currently the most commonly used one. We report a patient with central paralysis of the right upper extremity treated with contralateral C7 nerve transfer via the posterior spinal route. ⋯ We propose carrying out contralateral C7 nerve transfer via the posterior spinal route because of the shorter distance, no need for nerve transplantation, and low occurrence of the complications encountered with the prespinal route (such as vertebral artery injuries, esophageal fistula, and upper extremity pain when swallowing).
