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

. 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

Bilateral intracranial subdural osteomas of varying sizes imaged 7 years apart: illustrative case

up in the neurology clinic for a prolonged history of headaches. She had first presented 7 years earlier with headaches localized to the left frontotemporal region. At her initial presentation, magnetic resonance imaging (MRI) of her brain depicted a mass lesion measuring 1.3 cm in thickness and 5 cm in length that was initially interpreted as a subdural hematoma in the left frontoparietal region. There was no associated vasogenic edema, mass effect, or effacement of adjacent sulci or gyri, pointing toward chronicity of the mass ( Fig. 1A ). Head computed

image and sagittal image, respectively. There was no midline shift or herniation; however, residual small areas of suprasellar enhancement and persistent deformity of the anterior third ventricle can be seen in both images. One month postoperatively, the patient experienced an accidental fall, resulting in a subdural hematoma. The patient is otherwise healthy, but his vision has declined after the fall. He currently experiences left central vision loss and right temporal hemianopia; however, this is still subjectively improved compared with his symptoms before

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
