BACKGROUND Normal pressure hydrocephalus (NPH) treatment consists of using valves for drainage, as it is in general. Despite this, complications can occur, putting the patient at risk, and neurological monitoring crucial. OBSERVATIONS A 61-year-old male, who had been diagnosed with NPH 3 years prior was being treated a ventriculoperitoneal shunt programmable valve, presented to emergency department because traumatic brain injury due fall from standing height. No previous were reported. He an...
The localization of arteriovenous malformations (AVMs) intraoperatively in the setting an acute intracerebral hemorrhage (ICH) is crucial to avoid damage delicate vascular structures that may even further exacerbate bleed. Currently, surgical mapping using preoperative angiographic standard practice. We report use intraoperative ultrasound for diagnosis and AVM case a 61-year-old female with reported iodine contrast allergy previous severe reaction, limited resources, without other imaging...
Genitalia-related complications of ventriculoperitoneal shunts, such as scrotal migrations, are rare and most frequently presenting during the first year system placement, usually in pediatric population, due to several factors, including vaginal process patency increased abdominal pressure. Despite being typically benign, hernias, hydroceles, perforations, catheter migration scrotum can lead permanent disabilities lethal complications, shunt dysfunction. We report a case late-onset,...
Bilateral ophthalmic aneurysms are rare and involve two in the arteries, one on each, leading to potential symptoms such as vision loss headaches. The treatment options for aneurysms, ranging from surgery endovascular embolization observation, depend various factors, including aneurysm size patient's health. Microsurgery, while presenting complexities due intricate anatomy of anterior clinoid region, offers advantages enhanced decompression rates reduced recurrence. presented surgical video...
To assess the changes of intracranial pressure waveforms (ICPW) acquired noninvasively in a set acute hydrocephalus patients prior to and posterior interventions. Patients with clinical radiological diagnoses were evaluated for alterations ICPW by means system that detects cranial micro expansions just before immediately after The quantified difference between peaks (P1 P2), providing P2/P1 ratio. Fourteen aged from 26 73 years old included. Hydrocephalus etiologies normal hydrocephalus,...
Craniopharyngiomas are supra/parasellar lesions that often present with general, unspecific symptoms. Similarly, internal carotid artery (ICA) bifurcation giant aneurysms may also produce calcified, heterogeneous, parasellar expansive lesions, posing a relevant differential diagnosis due to their inherently different surgical strategies and risks. We report the case of 54-year-old female presenting progressive disorientation apathetic behavior. CT MRI reports described suprasellar...
How the prefrontal cortex (PFC) recovers its functionality following lesions remains a conundrum. Recent work has uncovered importance of transient low-frequency oscillatory activity (LFO; < 4 Hz) for recovery an injured brain. We aimed to determine whether persistent cortical dynamics contribute brain capability support 'normal life' injury.In this 9-year prospective longitudinal study (08/2012-2021), we collected data from patient E.L., modern-day Phineas Gage, who suffered lesions,...
The authors present the first report of a fracture tip kyphoplasty curette inside vertebral body, which occurred during procedure in patient with non-osteoporotic fracture. This highlights need further biomechanical research focused on shear load failure properties such type pre-bent curettes.
Although fluorescein is widely used for intraoperative angiography, some of its side effects remain obscure. In this report, we present the case a 41-year-old patient with chronic ischemia caused by moyamoya syndrome who underwent bypass revascularization angiography (FA). Immediately after surgery, presented homogeneous fluorescence entire skin. We discuss curious phenomenon as well other that may arise due to FA.
Despite mainly benign, exophytic subcutaneous cranial masses present with a myriad of differential diagnosis possibilities, ranging from simple, superficial lesions to complex involving the central nervous system. Although gold standard imaging modality for these is magnetic resonance imaging, Doppler Ultrasonography can be useful, inexpensive, and available tool evaluation that could potentially safely treated in primary care setting, would demand advanced neurosurgical care.This patient...
Sturge-Weber syndrome (SWS) is a capillary-venous malformation affecting the brain, eye, and adjacent trigeminal dermatomes of skin. This illness usually diagnosed during first years life. If left undiagnosed (and consequently untreated), condition could develop into severe refractory seizures, ischemic strokes, visual loss, early cognitive impairment. We report case 23-year-old female patient with port-wine facial stain, presenting her convulsive episode in adulthood, associated moderate...
