Radiative corrections: from medium to high energy experiments.

Radiative corrections are crucial for modern high-precision physics experiments, and are an area of active research in the experimental and theoretical community. Here we provide an overview of the state of the field of radiative corrections with a focus on several topics: lepton-proton scattering, QED corrections in deep-inelastic scattering, and in radiative light-hadron decays. Particular emphasis is placed on the two-photon exchange, believed to be responsible for the proton form-factor discrepancy, and associated Monte-Carlo codes.

Expanded Endoscopic Endonasal Clipping of a Giant Cavernous Carotid Aneurysm.

Cavernous carotid aneurysms are typically small, asymptomatic, and often do not require treatment. We present the case of a 59-year-old woman, a 3-pack-a-day smoker, who presented with the primary complaint of left retro-orbital pain, left complete ophthalmoplegia, left-sided blindness, and right abducens palsy. Imaging revealed a giant right cavernous carotid aneurysm, which had expanded to the contralateral cavernous sinus wall and superiorly through the diaphragm sellae.
