Pontine hemorrhage is a bleeding which occurs in pons. CT Brain is diagnostic... Organophosphate poisoning is ingestion of insect poison. these two has the same clinical picture of "constricted pin point pupil". But in opc poisoning we can smell the kerosene like odor from patient mouth and excessive salivation & secretion will be there..
Pontine hemorrhage is a type of intracerebral hemorrhage that occurs in the pons region of the brainstem. It can lead to symptoms such as difficulty with eye movements, facial weakness, and impaired consciousness. Emergency medical attention is needed as it can be life-threatening.
acute haemorrhage within the pons causing a characteristic clinical picture.
The patient complains of a severe headache and rapidly becomes unconscious, and then develops periodic respiration, pinpoint pupils, loss of "doll's head" ocular movements and tetraplegia. There is no flaccidity and the patient may rapidly go into decerebrate posturing. Hypertension is the main cause of pontine haematoma. CT is the first examination of choice and shows the hyperintense haematoma usually occupying a large part of the pons, sometimes with intraventricular rupture within the first ventricle

What is pontine?
The term "pontine" typically refers to structures or functions related to the pons, which is a region in the brainstem involved in various important functions like regulating sleep, breathing, and communication between different parts of the brain. In medical contexts, "pontine" may also refer to pathologies or conditions that affect the pons.
Why pontine lesion cause pinpoint pupil?
Pontine lesions can affect the fibers of the Edinger-Westphal nucleus, which is responsible for pupil constriction. Damage to this area can result in unopposed sympathetic input, causing the pupils to become pinpoint due to prolonged pupillary constriction.
What is pontine hemorrhage?
Pontine hemorrhage is bleeding in the pons, a part of the brainstem that controls essential functions like breathing, heart rate, and consciousness. It is a medical emergency that can lead to serious complications due to the critical structures in the area affected. Symptoms may include difficulty speaking, swallowing, or moving as well as changes in level of consciousness.
Where is the pneumotaxic center and the apneustic center located?
The pneumotaxic center is located in the upper pons of the brainstem, specifically in the pontine respiratory group. The apneustic center is located in the lower pons of the brainstem. Together, these centers help regulate the rhythmic breathing pattern.
What regulates smoothing of transitions from inspiration to expiration?
The process of smoothing transitions from inspiration to expiration is regulated by the respiratory centers in the brainstem, which coordinate the contraction of respiratory muscles. This includes the diaphragm and intercostal muscles, which work together to control the flow of air in and out of the lungs. Smooth transitions are important for maintaining a regular breathing pattern and efficient gas exchange in the body.
How does a pontine haemorrhage produce a pinpoint pupil?
A pontine, or brain stem hemorrhage, produces a pinpoint pupil because the fibers in the brain are unaffected. Therefore, dilation is interrupted, causing the pinpoint, but eyes can look relatively normal.
When was Pontine Paus born?
Pontine Paus was born in 1973.

What is the difference between haematoma and haemorrhage?
