We developed a simple quantifiable scoring system that predicts aneurysmal subarachnoid hemorrhage (aSAH) mortality, delayed cerebral ischemia (DCI), and modified Rankin scale (mRS) outcomes using readily available SAH admission data with SAH volume (SAHV) measured on computed tomography (CT). We retrospectively analyzed a cohort of 277 patients with aSAH admitted at our Comprehensive Stroke Center at Mayo Clinic in Jacksonville, Florida, between January 5, 2012, and February 24, 2022. We developed a mathematical radiographic model SAHV that measures basal cisternal SAH blood volume using a derivation of the ABC/2 ellipsoid formula (A = width/thickness, B = length, C = vertical extension) on noncontrast CT, which we previously demonstrated is comparable to pixel-based manual segmentation on noncontrast CT.

A case of brain injury with a transient syndrome of mainly disinhibited behaviour (Franz Binz) was the subject of the 1888 medical dissertation of Leonore Welt (∗1859 Chernivtsi, Ukraine; †1944 Geneva, Switzerland) which came to be discussed quite controversially. Although Binz was never fully forgotten, the similar "American crow-bar case" (Phineas Gage) attracted more interest. Welt's study, in contrast, provides not only well-illustrated neuropathological findings but also more detailed clinical data.
