Pachymeningeal en plaque metastasis from gastric cancer mimicking subdural hematoma: illustrative case

Hsuan-Yi Wu, Chee-Tat Lam, Ai Seon Kuan, Tong-Jong Chen, Chen-Shu Wu, and Ming-Cheng Tsai

after thoracoscopic segmentectomy in 2016 without recurrence. In March 2021, he presented with progressive right hemiparesis, and noncontrast computed tomography (CT) scanning of the brain revealed a left frontal-parietal-temporal chronic subdural hematoma (SDH) ( Fig. 1A and B ). After burr hole drainage was performed, the patient’s symptoms improved. In September 2021, the patient was admitted to our hospital because of hematemesis. Upper gastrointestinal pan-endoscopy revealed bleeding from malignant gastric ulcers in the gastric cardia. Hemostasis was achieved

Concomitant central venous sinus thrombosis and subdural hematoma in acute promyelocytic leukemia: middle meningeal artery embolization enables safe anticoagulation. Illustrative case

Kushagra Maini, Feroze Afzal, Dan-Victor Giurgiutiu, Scott Y. Rahimi, Manan Shah, Jeffrey A. Switzer, Fernando L. Vale, and Klepper Alfredo Garcia

. CT of the head postembolization revealed stable subacute left subdural hematoma. CT of the head prior to discharge showed stable subacute left lateral temporal subdural hematoma with a 5-mm left to right midline shift. CT of the head at the first follow-up appointment disclosed no evidence of any residual subdural hematoma. Procedure Before the procedure, the technical aspects of the procedure, as well as potential risks and benefits, were explained to the patient. After informed consent was obtained, the patient was brought to the angiography suite and

The first case of glioma detected by an artificial intelligence algorithm running on real-time data in neurosurgery: illustrative case

reliable diagnosis is still in its early stages. Although many different studies have shown that a reliable neurosurgical diagnosis could be made for different scenarios, such as subdural hematoma, 13 traumatic brain injury, 14 tumor detection, 15 and classification, 16 most of these studies are experimental. There are initiatives to create open-source 17 or commercial software for automated MRI interpretation. In a literature search, there were reports on one of the commercial systems which indicates that the use of a similar computed tomography (CT)-based system

Non-contrast–enhancing subdural empyema: illustrative case

Alexander D. Rebchuk, Stephano J. Chang, Donald E. G. Griesdale, and Christopher R. Honey

adjacent effacement of the sulci but without any brain edema, herniation, or midline shift ( Fig. 1 ). This was interpreted as most likely a chronic subdural hematoma given his recent falls. Dedicated vascular imaging (CT angiography) did not demonstrate any vessel occlusions or stenosis. A lumbar puncture was deferred since international normalized ratio and partial thromboplastin time were elevated. FIG. 1. Axial ( left ) and coronal ( right ) contrast-enhanced CT of the head demonstrating a nonenhancing left parietal subdural collection. The patient was

Pathophysiology and surgical treatment of spinal adhesive arachnoid pathology: patient series

hemorrhage from ruptured basilar aneurysm or dissection of the vertebral artery. The other patient suffered from acute spinal subdural hematoma of unknown origin. Trauma as the etiology was noted in 2 patients (severe head injury in 1; spinal cord injury in 1). Another 4 patients had different types of etiology: tuberculosis (caries), pyogenic meningitis, oil-myelography, and cerebrospinal fluid (CSF) leakage syndrome. The interval from etiological events to onset of symptoms of arachnoid adhesion in these 13 patients ranged from 1 to 744 months (mean 167.3 months, median

High-flow bypass for giant dolichoectatic vertebrobasilar aneurysms: illustrative cases

embolism; PICA = posterior inferior cerebellar artery; pst = posterior; SDH = subdural hematoma; TL/TC = translabyrinthine/transcochlear; VPS = ventriculoperitoneal shunt. High-Flow Bypass Technique Both patients had insufficient posterior communicating artery collateral supply. Consequently, we elected to perform an ECA-to-PCA (P2) high-flow bypass to initially establish an alternative posterior circulation before proximal Hunterian ligation. Although a detailed description of this surgical technique has been published previously, 12 we herein describe

consistent with those above. The underlying mechanism is supposedly similar to that of a chronic subdural hematoma, and the pathophysiology resulting in hematoma enlargement, a contemplative cycle of hemorrhage, coagulation, fibrinolysis, and rebleeding from the neovascular outer membrane. In contrast to acute-onset PA, this patient showed visual deterioration due to slow cystic enlargement, and a serous dark reservoir was observed within the cyst. Combined pathological examination resulted in diagnosis of CEEH after pituitary stroke associated with pituitary adenoma. In
