Cerebral edema early stroke or hypoxia, cardiac arrest, and pseudotumor cerebri. During an ischemic stroke, a lack of oxygen and glucose leads to a breakdown of the sodium-calcium pumps on brain cell membranes, which in turn results in a massive buildup of sodium and calcium intracellularly. This causes a rapid uptake of water and subsequent swelling of the cells. It is this swelling of the individual cells of the brain that is seen as the main distinguishing characteristic of cytotoxic edema, as opposed to vasogenic edema, wherein the influx of fluid is typically seen in the interstitial space rather than within the
Persistent edema of rosacea Persistent edema of rosacea Persistent edema of rosacea (also known as "Chronic upper facial erythematous edema," "Morbihan's disease," or "Rosaceous lymphedema") is a hard, nonpitting edema found on the areas involved, those mainly being the forehead, glabella, upper eyelids, nose, and/or cheeks. Persistent edema of rosacea is an uncommon cutaneous condition characterized by a hard, nonpitting edema restricted to the forehead, glabella, upper eyelids, nose, and cheeks. This condition is also known as chronic upper facial erythematous edema, Morbihan's disease, morbus Morbihan, and rosaceous lymphedema. Despite the name, it is unclear whether this condition is a distinct disease or a
