-associated odontogenic cerebral abscess in an immunocompetent patient: A case report.

Key Clinical Message: can cause rare odontogenic brain abscesses in immunocompetent patients, highlighting the importance of considering uncommon pathogens in central nervous system infections. With only three reported cases of cerebral abscesses and one pituitary abscess caused by this microorganism, tailored diagnostic methods and individualized treatment regimens are crucial for accurate management.

Abstract: Brain abscesses present diagnostic and therapeutic challenges, with infections being exceptionally rare in the central nervous system.

Fluoroscopy-Assisted Freehand Versus 3D-Navigated Imaging-Assisted Pedicle Screw Insertion: A Multicenter Study.

Introduction: Pedicle screw placement is a widely accepted surgical procedure for spinal fixation. Despite increases in knowledge about and expertise in pedicle screw insertion techniques, overall reported screw misplacement rates are still high. Spinal neuronavigation and intraoperative computed tomography (CT) imaging improves the accuracy and safety of pedicle screw placement through the continuous monitoring of screw trajectory.

Bilateral post-traumatic hygromas in patient with frontotemporal dementia.

Background: Frontotemporal dementia (FTD) is a highly disabling neurologic disorder characterized by behavioral alterations and movement disorders, involving patients with a mean age of 58 years. We present a unique case of a patient suffering from FTD who developed post traumatic bilateral hygromas.

Case Description: A 52-year-old male patient, with an history of head trauma 3 months before, was admitted to our department for recurrent motor seizures.

Spinal cord compression from cutaneous malignant peripheral nerve sheath tumor metastasis in a patient with neurofibromatosis Type 1.

Background: Neurofibromatosis Type 1 (NF-1) and previous irradiation are two common risk factors that can result in malignant peripheral nerve sheath tumors (MPNSTs), extremely rare soft-tissue sarcomas. Here, a 63-year-old male with NF-1 presented with diffuse spinal metastases from a subcutaneous MPNST.

Case Description: A 63-year-old male with NF-1 presented acutely with paraplegia and urinary incontinence.

Thoracic dumbbell spinal chordoma mimicking a schwannoma.

Background: Epidural dumbbell-shaped chordomas are localized slow growing, and malignant/aggressive neoplasms. Here, we present a 62-year-old male with a T3-T4 dumbbell-shaped chordoma and reviewed the appropriate literature.

Case Description: A 62-year-old male presented with a three-month history of thoracic pain.

Delayed brain reexpansion in schizophrenic patient affected by trabecular type chronic subdural hematoma.

Background: Chronic subdural hematoma (cSDH) represents a complex and unpredictable disease, characterized by high morbidity and mortality, especially in elderly patients. Factors affecting the postoperative brain reexpansion along to cSDH recurrence have not been yet adequately investigated. The authors presented the case of a schizophrenic patient affected by trabecular type cSDH that presented a delayed brain reexpansion despite a craniotomy and membranotomy.

Dural splitting reconstruction in retethering after lipomeningocele repair: Technical note.

Background: Tethered spinal cord syndrome (TCS) can occur after the surgical repair of lipomeningoceles (LMCs). In these cases, the tethering results from postoperative adhesions between the spinal cord and the overlying repaired dura. A watertight dural closure using the residual dura and/or the surrounding tissues does not always provide enough space for the spinal cord and risks retethering.

Primary spinal Burkitt's lymphoma: Case report and literature review.

Background: Burkitt's lymphoma is a non-Hodgkin B-cell lymphoma, occurring mostly in Equatorial Africa. According to the WHO, classification is three different variants: sporadic, endemic, and immunodeficient-associated. Here, we present a patient with "sporadic" primary epidural Burkitt's lymphoma resulting in chronic low back pain (LBP).

Spontaneous anterior cervicothoracic spinal epidural hematoma extending to clivus in SARS-CoV-2 infection.

Background: The treatment of spontaneous spinal epidural hematomas (SSEHs), depending on the lesion size and myeloradicular involvement, can be surgical or conservative. Here, we present a 55-year-old patient who sustained a SSEH several months following a systemic SARS-CoV-2 infection.

Case Description: A 55-year-old immunocompromised female (i.

Navigation-assisted extraforaminal lumbar disc microdiscectomy: Technical note.

Background: Extraforaminal lumbar disc herniation (ELDH) amounts of 7%-12% of all lumbar disc herniations. Although they have already been widely described, an optimal treatment is still under discussion in the literature.

Objective: We describe a novel application of navigation using 2D/3D imaging system to plan an adequate surgical trajectory and performing a neuronavigated microdiscectomy in ELDH that has not been previously described.

Rare spondylodiscitis due to .

Background: Nontuberculous mycobacteria (NTM) represents an important cause of infection, particularly in immunocompromised patients. Spondylodiscitis is unusual and may be associated with underlying causes such as drug abuse. Timely diagnosis and treatment are critical, as without this, patients will demonstrate progressive neurological deterioration.

Cervical radiculopathy as first presentation of CD3-positive diffuse large B-cell lymphoma of the cervico-thoracic junction.

Background: Diffuse large B-cell lymphoma (DLBCL) in rare cases can presents an unusual expression of CD3 T-cell specific antigen. We report the first case of a CD3-positive DLBCL of the cervico-thoracic junction presenting with persistent cervical radiculopathy.

Case Presentation: A 74-years-old male patient presented a severe and persistent right C8 radiculopathy associated with right-sided neck pain, progressive numbness and weakness of the right arm.

Intradural lumbar disc herniations at the L1-L2 level: A case study and literature review.

Background: Intradural disc herniations (IDHs) are rare occurrences (0.26-0.30%), and most frequently involve the lumbar spine at the L4-L5 level.

A new tool to improve pedicle screw placement accuracy in navigated spine surgery: a monocentric study.

Background: Navigated instrumented spine surgery is burden by a low but significant screw mispositioning risks, respectively, for the 2D imaging system from 15% to 40% and, for the 3D imaging system, ranging from 4.1% to 11.5%.
