Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
The danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. [1] [2]: 345–346 Due to the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infection from the nasal area to spread to the brain, causing cavernous sinus thrombosis, meningitis, or brain abscess.
An internal bleeding require to call to emergency medical services. In the event of bleeding caused by an external source (trauma, penetrating wound), the patient is usually inclined to the injured side, so that the 'good' side can continue to function properly, without interference from the blood inside the body cavity.

Bleeding may not be readily apparent; internal organs such as the liver, kidney and spleen may bleed into the abdominal cavity. The only apparent signs may come with blood loss. Bleeding from a bodily orifice, such as the rectum, nose, or ears may signal internal bleeding, but cannot be relied upon.
Little described the area as being "about half an inch ... from the lower edge of the middle of the column [septum]". [7] Kiesselbach's plexus is named after Wilhelm Kiesselbach (1839–1902), a German otolaryngologist who published a paper on the area in 1884. The area may be called Little's area, [4] Kiesselbach's area, or Kiesselbach's triangle.
Because of the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infections from the nasal area to spread to the brain. For this reason, the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla, is known as the danger triangle of the face. [13]

Other location such as bleed within the cerebral cortex and intracranial bleed in people younger than 50 years should prompt further investigations on other causes of bleed such as brain tumour or cerebral arteriovenous malformation. The bleed can be very small without any significant effect on surrounding brain or large hemorrhage that exerts ...
