Background: A tailor-made treatment is often required in arteriovenous malformations (AVMs) depending on the individual situation. In most cases, treatment strategy is usually determined according to the patient's Spetzler-Martin grade. However, in the present case, we were not able to treat the patient following the usual guidelines because of neurological symptoms and pregnancy. Case Description: We describe a rare case of a 31-year-old woman in the 15th week of gestation who presented with an AVM in the anterior perforated substance (APS)...

Background: There is scant literature evaluating the indications, techniques, and outcomes of minimally invasive spine (MIS) surgery undertaken for pediatric and adolescent spine pathology. Our study attempts to evaluate the safe and effective use of MIS techniques in pediatric and adolescent patients and to appreciate the technical nuances of MIS surgery for this age group. Methods: Consecutive pediatric and adolescent patients undergoing elective MIS lumbar procedures, from 2008 to 2016, were retrospectively analyzed from the practice of a single fellowship-trained academic spinal neurosurgeon...

Background: Sinus pericranii (SP) is a rare vascular malformation consisting of an abnormal communication between the extra- and the intracranial venous system. It occurs due to the adhesion of vessels without a muscular layer or a hemangioma on the outer surface of the skull through diploic vessels, communicating with an intracranial venous sinus. Case Description: A 10-month-old female presented with a pulsatile mass on the posterior parietal region. Investigation with brain vascular examinations showed a venous malformation communicating with the superior sagittal sinus under the scalp, without arterial feeder or nidus...

Background: Charcot spinal arthropathy (CSA) clearly represents a challenge in long-term spinal cord injury patients, one that can have extremely uncomfortable and potentially lethal outcomes if not managed properly. Case Description: A 66-year-old man with a history of complete C7 quadriplegia presented with new-onset autonomic dysreflexia that resulted from Charcot spinal arthropathy (CSA). Pathologic instability, in the atypical site of the mid-thoracic spine, spanning from the T8-T9 vertebral levels was appreciated on physical exam as an audible, palpable, and visible dynamic kyphosis; kyphosis was later confirmed on neuroimaging...

Background: Approximately 20-30% of all intracranial metastases are located in the posterior fossa. The clinical evolution hinges on factors such as tumor growth dynamics, local topographic conditions, performance status, and prompt intervention. Fourth ventricle (V4) compression with secondary life-threatening obstructive hydrocephalus remains a major concern, often requiring acute surgical intervention. We have previously reported on the application of adaptive hypofractionated Gamma Knife Radiosurgery in the acute management of critically located metastases, a technique known to us as rapid rescue radiosurgery (3R)...

Gautam Dutta, Robin Gupta, Manish Garg, Daljit Singh, Hukum Singh, Arvind K Srivastava, Anita Jagetia
Background: Gliosarcoma is a rare high-grade malignant tumor and a variant of glioblastoma characterized by biphasic glial and mesenchymal components. Gliosarcomas occur most commonly in the fifth or sixth decade of life and have a temporal lobe predilection. Occurrence in the pediatric population is extremely rare. Case Description: Here, we report the case of an 8-year-old child with histologically confirmed gliosarcoma at the parieto-occipital lobe. Only a subtotal resection of the tumor mass could be performed in view of massive bleeding from the tumor bed; and despite postoperative chemotherapy and radiotherapy, the tumor recurred in a short span of time...

Background: Primary lymphomas in the choroid plexus are much less frequent than primary lymphomas in the brain parenchyma. Case Description: A 66-year-old male patient was referred to our department with a right intraventricular mass that had been diagnosed by biopsy at another hospital as anaplastic ependymoma. The patient underwent subtotal removal of the tumor via a transcortical inferior temporal gyrus approach. The mass was attached to the choroid plexus in the right atrium...

Background: Exogenous sex hormones may play a role in meningioma development and growth. Thus, transsexual patients being on long-standing hormone replacement therapy (HRT) may be at particular risk for meningioma development and growth. Here we present two cases of two male-to-female transsexual patients taking HRT for an extended period of time with both patients requiring surgical treatment at our institution due to multiple growing meningiomas. Case Description: The first patient was a 50-year-old genetic male (male-to-female transsexual) who presented 7 years after an extensive sex-change operation due to progressive bitemporal visual defects...

Marcelo D Vilela, Bruno P Braga, Hugo A S Pedrosa
Background: Iliac screw placement is challenging due to the particular anatomy of the ilium. Most series have reported the use of relatively short (≤90 mm in length) screws despite a long iliac buttress, which has an average length of 129 mm in females and 141 mm in males. This study describes a series of 14 patients who underwent placement of long iliac screws (≥100 mm in length) as part of a spinopelvic fusion utilizing fluoroscopy alone. Methods: All patients who received at least one long iliac screw were included in this study...

Burke A Cunha, Ismail Jimada, Karishma Chawla
Background: Infectious endocarditis (IE) clinically manifests as either subacute bacterial endocarditis (SBE) or acute bacterial endocarditis (ABE). Neurologic manifestations are markedly different for these two entities. ABE is caused by invasive, highly virulent pathogens (e.g., Staphylococcus aureus ), whereas SBE is attributed to relatively avirulent, non-invasive organisms (e.g., viridans streptococci ). Methods: Here, we reviewed the clinical and radiographic presentations of a patient with cranial complications attributed to ABE...

We have reviewed the English literature published in the last 70 years on Diseases of the Vertebral Basilar Circulation, or Posterior Circulation Disease (PCD). We have found that errors have been made in the conduct and interpretation of these studies that have led to incorrect approaches to the management of PCD. Because of the difficulty in evaluating the PC, the management of PCD has been incorrectly applied from anterior circulation disease (ACD) experience to PCD. PCD is a common form of stroke affecting 20-40% patients with stroke...

Background: Some patients with moyamoya disease (MMD) show broad infarction with moderate internal carotid artery (ICA) stenosis, whereas others with complete ICA occlusion show no infarction. This suggests that other factors contribute to the occurrence of infarction. Contributing factors predictive of cerebral infarcts must be identified for the prevention of infarction and the consequent neurological deficits. Methods: We examined data from 93 patients with confirmed MMD for the presence of infarction ( n = 72), transient ischemic attack (TIA, n = 41), asymptomatic presentation ( n = 51), or hemorrhage ( n = 22) in 186 bilateral cerebral hemispheres...

Background: Infratentorial subdural empyemas in children are extremely rare and potentially lethal intracranial infections. Delay in diagnosis and therapy is associated with increased morbidity and mortality. Case Description: A 4-year-old boy presented with cerebellar signs following a failed treatment of otitis media. Imaging studies revealed a subdural empyema and left transverse and sigmoid sinus thrombosis. The empyema was evacuated operatively and antibiotic treatment was initiated and administered for 6 weeks...

Background: Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is associated with an increased prevalence of some malignancies. However, some observational studies have revealed an ever-decreasing prevalence of HIV in glioma patients. The relationship between HIV and brain gliomas has not been well established. Methods: A cross-sectional study was carried out in sub-Sahara Africa, a high HIV prevalence setting, to determine the prevalence of HIV among all glioma patients over a 2-year period...

Leopoldo Luciano Luque, Maximo Marchetti, Daniel Seclen, Ariel Sainz, Marcelo Platas, Jorge Lambre
Neurenteric cysts (NC) are rare, benign, congenital lesions, caused by abnormal or persistent communications between neuroectodermal structures, the notochord and endodermal tissue. They present mainly in the pediatric population or young adults, coexisting with spinal, gastrointestinal or respiratory malformations. They are typically intradural extramedullary tumors, with intramedullary lesions the exception. The objective of this paper is to report the case of a cervical intramedullary neuroenteric cyst in a young adult, without coexisting malformations...
