Background Rosette-forming glioneuronal tumors (RGNT) are slow-growing WHO Grade I tumors that are characterized by mixed histology and rosette formation. Although typically located in the posterior fossa, these tumors can rarely originate elsewhere. Here, we describe the fourth case in literature where an RGNT was localized to the lateral ventricles and detail the treatment approach. Case description A 41-year-old male presented with a 10 day history of gradually worsening headaches and mild gait difficulty. Computed tomography and magnetic resonance imaging (MRI) identified a heterogeneously enhancing 6.0 cm left lateral ventricular cystic mass with hydrocephalus. An interhemispheric transcallosal approach was performed for tumor debulking. The mass was emanating from the roof of the left lateral ventricle. Sub-total resection (STR) was achieved. Pathology showed a glioneuronal neoplasm with vague neurocytic rosettes and loose perivascular pseudorosettes. Tumor vessels were thickly hyalinized and contained eosinophilic granular bodies and Rosenthal fibers. Tumor stained positive for GFAP, S-100, OLIG2, and SOX10, and patchy positive for epithelial membrane antigen (EMA), D2-40, CD99, and p16. Neurocytic rosettes and perivascular structures stained positive for synaptophysin. The patient was discharged home uneventfully and remained intact at his 6-month follow-up visit. Long-term care included MRI surveillance with repeat surgery being considered in case of progression. Conclusion In this report, we describe the fourth case of an RGNT being isolated to the lateral ventricles and the first where it stained positive for EMA and D2-40. Our patient's uneventful recovery after STR indicates that surgery alone continues to be a viable initial treatment option.Background Hyperextension thoracic spine fractures (HTSFs) typically involve the anterior ligamentous complex of the spine. These patients often present with paraplegia and warrant early surgical reduction/fixation even though few deficits resolve. Here, we present the unusual case of a 40-year-old male whose paraparetic deficit resolved following reduction/fixation of a T7-T8 HTSF. Case description A 40-year-old male presented with a thoracic computed tomography (CT) documented T7- T8 HTSF following a motor vehicle accident. His neurological examination revealed severe paraparesis, but without a sensory level (ASIA motor score 78). The chest CT angiogram scan revealed a hypodensity in the aorta, representing a small traumatic aortic dissection responsible for the patient's right hemothorax; 450 ml of blood was removed on chest tube placement. He underwent urgent/emergent thoracic spine reduction and fixation at the T7-T8 level. Within 5 postoperative months, he recovered fully neurological function (ASIA motor score 100). Conclusion We recommend urgent/emergent surgical reduction/stabilization for patients with thoracic HTSF to decrease offer the potential for neurological recovery and avoid secondary injury due to continued compression.Background Tortuous/abnormal vertebral arteries (VAs) sometimes cause neurovascular compression syndromes (NVCs), such as trigeminal neuralgia, hemifacial spasm, and, rarely, myelopathy/radiculopathy. Abnormalities/tortuosity of the VA at the level of the atlas and axis are of particular note; these may be characterized by a persistent first intersegmental artery (PFIA) and C2 segmental type of VA. Herein, we report a 72-year-old male who presented with cervical myelopathy/radiculopathy due to bilateral tortuosity of the PFIA resulting in spinal cord compression at the craniocervical junction. Case description A 72-year-old male presented with cervical pain when turning his neck and progressive gait disturbance. The neurological examination demonstrated a moderate myeloradicular syndrome (Nurick Grade III). The magnetic resonance revealed compression of the medulla and spinal cord due to tortuosity of both dorsal VA at the C1 vertebral level. The three-dimensional computed tomography angiogram confirmed bilateral PFIA running medially. In addition, the left side of VA forms fenestration. Surgery through a C1 laminectomy and midline small suboccipital craniectomy, both VAs were transposed and tethered to the ipsilateral dura utilizing Aron Alpha and vinyl prostheses. In addition, a large vinyl prosthesis was inserted between both VAs to protect them from contacting the spinal cord. Following this decompressive procedure, the patient's symptoms fully resolved, and he remains asymptomatic 10 years later exhibiting no recurrent vascular pathology. Conclusion Microvascular decompression of anomalous VAs contributing to cord compression at the C1 level was safe and effective in a 72-year-old male.Background Intracranial Ewing's sarcoma (ES) is a rare entity with less then 15 cases reported in the literature. It belongs to a family of round-cell neuroectodermally derived tumors bearing many similarities to peripheral primitive neuroectodermal tumor (pPNET). There is currently no established treatment protocol. Reported cases are treated with either surgery alone or surgery with adjuvant chemotherapy and radiation. Case description We describe a case of intracranial left frontal ES in a 19-year-old patient who presented with change in behavior. Diagnosis was unclear based on radiological findings on MRI and CT alone. MRI brain with contrast demonstrated a large extra-axial ovoid heterogeneously enhancing left frontal convexity mass. The patient underwent gross total resection with adjuvant chemotherapy and radiation. No local or systemic recurrence was found at 12 months postoperatively. Conclusion Intracranial ES/pPNET is rare tumor with nonspecific clinical presentation and radiological findings. They are locally invasive. Cyclosporine Surgery with adjuvant chemoradiation is the mainstay treatment. Distinction of pPNET and cPNET is important for therapeutic and prognostic purposes.Background Neurosarcoidosis is a rare disease. In the spine, it commonly presents as an intramedullary lesion. Epidural spinal lesions are extremely rare. Case description A 29-year-old patient presented with a 22-month history of progressive neck, upper limb pain, and myelopathy. The cervical MRI showed a large epidural mass infiltrating the paraspinal soft tissue. After an open biopsy, the diagnosis of neurosarcoidosis was established and was followed-up by appropriate medical management. Conclusion To manage cervical epidural neurosarcoidosis, first, you must obtain a tissue diagnosis and then follow with appropriate medical management.
