Some diseases present with symptoms similar to erythromelalgia. Complex regional pain syndrome (CRPS), for instance, presents with severe burning pain and redness except these symptoms are often unilateral (versus symmetric) and may be proximal instead of purely or primarily distal. Furthermore, attacks triggered by heat and resolved by cooling ...
The majority of neonatal cases (90%) result from applying a vacuum to the head at delivery (ventouse-assisted delivery).The vacuum assist ruptures the emissary veins (i.e., connections between dural sinus and scalp veins) leading to accumulation of blood under the aponeurosis of the scalp muscle and superficial to the periosteum.
Sneddon's syndrome is a progressive, noninflammatory arteriopathy leading to the characteristic skin condition and to cerebrovascular problems, including stroke, transient ischemic attack (TIA), severe but transient neurological symptoms thought to be caused by cerebral vasospasm, coronary disease and early-onset dementia.
Characteristic signs and symptoms include: Skin rash: The most prominent feature is a reddish-purple rash that appears on the lower legs, typically below the knees and above the ankles. The rash is often described as blotchy, mottled, or net-like (reticular in appearance). [6] [7] In some cases, the rash may extend to the dorsum of the feet. [8]
Emissary veins have an important role in selective cooling of the head. They also serve as routes where infections are carried into the cranial cavity from the extracranial veins to the intracranial veins. There are several types of emissary veins including the posterior condyloid, mastoid, occipital and parietal emissary veins. [1]
Variable vessel vasculitis (VVV) is a kind of vasculitis that may impact vessels of all sizes (small, medium, and large) and any type (arteries, veins, and capillaries), with no particular type of vessel being predominantly affected. [33] This category includes Behcet's disease (BD) and Cogan's syndrome (CS). [8]
People with thrombophlebitis complain of pain along the affected area. Some report constitutional symptoms, such as low-grade fever and aches. On physical examination, the skin over the affected vein exhibits erythema, warmth, swelling, and tenderness. Later in the disease, as induration subsides, erythema gives way to a ruddy or bruised color ...
The frontal crest of the frontal bone ends below in a small notch which is converted into a foramen, the foramen cecum (or foramen caecum), by articulation with the ethmoid. The foramen cecum varies in size in different subjects, and is frequently impervious; when open, it transmits the emissary vein from the nose to the superior sagittal sinus.
