Patients with penetrating head trauma with retained projectiles develop intracranial abscesses as a common complication. The most common presentation is a suddenly worsening headache. The most common pathogen identified is staphylococcus. Outcomes are related to adherence of Matson's tenets. This case study details the presentation of a 19-year-old patient that presented to the neurological surgery clinic without neurologic deficits. Further questioning revealed complaints of intermittent diffuse headaches with bilateral upper extremity shock-like sensation for two weeks...

Renal Clear Cell Carcinoma (RCC) comprises over 80% of renal malignancies in adults. Thyroid gland metastasis is rare in RCC. Few studies have described cases of RCC mistaken for benign arteriovenous malformation (AVM). To the best of our knowledge, an AVM arising from underlying RCC metastasis to the brain has not yet been reported. The current study presents a case of RCC metastasis to the thyroid gland, with an AVM identified to be a result of metastatic involvement in the brain. A 45-year-old African-American female presented with left-sided weakness, slurred speech, facial droop and seizure...

BACKGROUND: Primate neurobiologists use chronically implanted devices such as pedestals for head stabilization and chambers to gain access to the brain and study its activity. Such implants are skull-mounted, and made from a hard, durable material, such as titanium. NEW METHOD: Here, we present a low-cost method of creating customized 3D-printed cranial implants that are tailored to the anatomy of individual animals. We performed pre-surgical computed tomography (CT) and magnetic resonance (MR) scans to generate three-dimensional (3D) models of the skull and brain...

Over 60% of all patients with dura mater graft-associated Creutzfeldt-Jakob disease (dCJD) have been diagnosed in Japan. The incubation period has ranged from 1 to 30 years and the age at onset from 15 to 80 years. Here, we report a 77-year-old male Japanese autopsied dCJD case with the longest incubation period so far in Japan. He received a cadaveric dural graft at the right cranial convexity following a craniotomy for meningioma at the age of 46. At 30 years post-dural graft placement, disorientation was observed as an initial symptom of dCJD...

OBJECTIVE: Cerebrospinal fluid (CSF) leak is a well-known complication of skull or sinus surgery. Radionuclide cisternography has high sensitivity for detection of CSF leak, commonly performed in conjunction with radioactivity assay of nasal pledgets. Our objective was to highlight the usefulness of single photon emission tomography/computed tomography (SPET/CT) in radionuclide cisternography by presenting a case of a 41 years old man with right sided rhinorrhea following craniotomies and sinus surgery, who was subjected to radioactivity assay of nasal pledgets and radionuclide cisternography for suspected CSF leak...

BACKGROUND: Transorbital intracranial penetrating trauma with a retained intracranial foreign body is a rare event lacking a widely accepted diagnostic and therapeutic algorithm. Intraoperative catheter angiography (IOA) has been advocated by some authorities to rule out cerebrovascular injury before and/or after removal of the object, but no standard of care currently exists. CASE DESCRIPTION: A 19-year-old man was involved in a construction site accident whereby a framing nail penetrated the left globe, traversed the lateral bony orbit, and terminated in the midtemporal lobe...

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is a rare condition with the potential to cause severe morbidity and mortality. CVST can also occur after vestibular schwannoma (VS) surgery with the thrombosis of transverse and sigmoid sinus. However, there is not a single report of superior sagittal sinus (SSS) thrombosis after VS surgery reported in the literature. CASE DESCRIPTION: A 45-year-old woman presented to our center with large left-sided solid cystic VS...

Nonmissile orbitocranial penetrating brain injuries are uncommonly dealt with in a civilian context. Surgical management is controversial, due to the lack of widely accepted guidelines. A 52-year-old man was hit in his left eye by a metallic foreign body (FB). Head computed tomography (CT) scan showed a left subcortical parietal FB with a considerable hemorrhagic trail originating from the left orbital roof. Surgical treatment was staged; an exenteratio oculi and a left parietal craniotomy to extract the FB under intraoperative CT guidance were performed at post trauma day third and sixth, respectively...

BACKGROUND: Patients often report sounds in the head after craniotomy. We aim to characterize the prevalence and nature of these sounds, and identify any patient, pathology, or technical factors related to them. These data may be used to inform patients of this sometimes unpleasant, but harmless effect of cranial surgery. METHODS: Prospective observational study of patients undergoing cranial surgery with dural opening. Eligible patients completed a questionnaire preoperatively and daily after surgery until discharge...

Primary delayed onset craniosynostosis is a rarely reported phenomenon. The unique case of a 2-year-old boy who had computed tomography (CT) scans performed 20 months apart demonstrating the post-gestational development of sagittal suture craniosynostosis is presented. The otherwise healthy male initially presented to the emergency department at age 7 months with soft tissue swelling over his left parietal region secondary to a fall. A CT scan revealed a possible left parietal skull fracture without intracranial pathology and patent cranial sutures with a normocephalic calvarial configuration...

BACKGROUND: Isolated cortical vein thrombosis (ICVT) being a rare condition (6% of intracranial vein thromboses), no clinical guidelines and few radiologic clues to it have been established. ICVT mostly appears in conjunction with sinus vein thromboses. ICVTs primarily occur during pregnancy and puerperium (35%). The great variability of cortical veins and difficulty identifying small occluded vessels complicate ICVT diagnosis. We present the first case of isolated ipsilateral dural thickening and enhancement as a potential radiologic sign of ICVT shown on magnetic resonance imaging...

BACKGROUND: Primary intracranial leiomyoma is an extremely rare occurrence of a low-grade mesenchymal tumor characterized by a proliferation of smooth muscle cells. When present, these lesions predominantly occur in immunocompromised patients in the setting of infection or transplant and have not been known to involve the ventricular system of the brain. In this report, we describe a case of primary leiomyoma of the lateral ventricle in an immunocompetent patient. CASE DESCRIPTION: A 30-year-old man with no medical history presented with progressive diplopia and occipital headaches...

Decompressive craniotomy (DC) in children is a life-saving procedure for the treatment of refractory intracranial hypertension related to traumatic, ischemic and infectious lesions. Different surgical procedures have been proposed including uni or bilateral hemicraniectomy, bi-frontal, bi-temporal, or bi-parietal craniotomies. DC can avoid the cascade of events related to tissue hypoxia, brain perfusion reduction, hypotension and the evolution of brain edema that can be responsible for brain herniation. The monitoring of intracranial pressure (ICP) is very important to take a decision as well as the value of Trans cranial Doppler (TCD)...

BACKGROUND: Neonatal in-hospital falls occur relatively frequently, although they are likely underreported. Significant intracranial head trauma from a fall or birth injury is not common in the immediate newborn period. Furthermore, intracranial bleeding requiring surgical intervention is exceedingly rare. We present an unusual case of an in-hospital fall in the delivery room requiring neurosurgical intervention. CASE REPORT: A term infant, appropriate for gestational age, delivered precipitously from a maternal standing position...

Ruptured aneurysms with intraparenchymal hematoma and mass effect are primarily treated by surgical clipping. In this video presentation, a 68 year old male with a large ruptured right ICA bifurcation aneurysm is presented. Patient's neurological exam was rapidly deteriorating, therefore the patient was transferred to the operating theater after initial evaluation by CT and CT angiogram. A pterional craniotomy was performed, the frontal hematoma was partially removed and the aneurysm was clipped. Residual hematoma was removed after securing the aneurysm and the aneurysm dome was punctured(detail of surgical clipping in the video)...

BACKGROUND: The impact of antithrombotic agents (warfarin, clopidogrel, ASA) on traumatic brain injury outcomes is highly controversial. Although cerebral atrophy is speculated as a risk for acute intracranial hemorrhage, there is no objective literature evidence. MATERIALS AND METHODS: This is a retrospective, consecutive investigation of patients with signs of external head trauma and age ≥60 years. Outcomes were correlated with antithrombotic-agent status, coagulation test results, admission neurologic function, and CT-based cerebral atrophy dimensions...
