Spontaneous middle meningeal arteriovenous fistula without cortical venous reflux presenting with acute subdural hematoma: illustrative case

Masahiro Yabuki, Yosuke Akamatsu, Hiroshi Kashimura, Yoshitaka Kubo, and Kuniaki Ogasawara

–14 We demonstrate a rare case of spontaneous acute subdural hematoma (SDH) caused by an MMAVF without CVR and discuss the mechanism of hemorrhagic presentation based on the findings during transarterial Onyx embolization. Illustrative Case A 17-year-old previously healthy male presented to our emergency department with the acute onset of headache. The patient had no history of head trauma. Computed tomography (CT) revealed a left acute SDH without significant mass effect ( Fig. 1A ). T2-weighted magnetic resonance imaging (MRI) performed on admission showed no

Infantile traumatic pericallosal aneurysm: illustrative case

Zachary S Hubbard, Conor M Cunningham, Brian F Saway, Matthew J Triano, Aaron T Miller, Guilherme Porto, Libby Kosnik Infinger, and Alejandro M Spiotta

Nonaccidental trauma (NAT) is a leading cause of infantile injury and death in the United States. 1 , 2 An estimated 2.07 children per 100,000 died in the United States as a result of abuse or neglect in 2010. 3 Over 50% of all fatalities resulting from child abuse occur in those under the age of 12 months. 4 Abusive head trauma is most commonly characterized by skull fracture, subdural hematoma (SDH), cerebral edema, and retinal hemorrhages. 1 , 5 Traumatic cerebral aneurysms (TCAs) are a rare sequela of abusive head trauma in infants. 6 , 7 The rate

Ruptured aneurysms at the distal superior cerebellar artery successfully treated by combining occipital artery–superior cerebellar artery anastomosis and endovascular therapy: illustrative case

Takenori Ogura, Taketo Hatano, Masaomi Koyanagi, Taisuke Kitamura, and Daisuke Yamada

-stage treatment in a hybrid operating room was chosen. A major concern associated with combined treatment is hemorrhagic complications caused by heparinization. The potential for incidence of intracranial hemorrhage, such as subdural hematoma, is a concern associated with two-stage treatments performed soon after bypass surgery. In this regard, single-stage treatment is considered beneficial because adequate hemostasis can be confirmed before wound closure after endovascular treatment. Although our combined treatment strategy provided new insights, it had several limitations
