Pneumocephalus is the presence of air or gas within the cranial cavity.It is usually associated with disruption of the skull: after head and facial trauma, tumors of the skull base, after neurosurgery or otorhinolaryngology, and rarely, spontaneously.Pneumocephalus can occur in scuba diving, but is very rare in this context. If there is a valve mechanism which allows air to enter the skull but ...

Learn about this rare inflammatory condition that affects the brain and lungs, including its causes, symptoms, and treatment options.

Intracranial gas is commonly detected on neuroimaging. The recognition of this finding can at first blush be unsettling. Being able to localize this gas to a specific compartment: intraarterial, intravenous, intraparenchymal, subdural, epidural, subarachnoid and intraventricular, is the first step in determining the importance of the gas.

2024年12月11日 · Pneumocephalus, also known as pneumatocele or intracranial aerocele, is the presence of air in the epidural, subdural, or subarachnoid spaces, the brain parenchyma, or ventricular cavities.[1] Lecat first described this condition in 1741, but Luckett independently coined the term "pneumocephalus" in 1913. Wolff used the same term to describe the …

Horizontally oriented lumbar wound. Imaging. Following the hospital’s trauma protocol, a CT full spine was performed. CT imaging showed a large collection of intraspinal, most probable subdural air, ascending from the low-lumbar wound between the spinous processes of L4 and L5, upwards to the cervical spine and dorsal of the clivus (Fig. 2). ...

2024年3月19日 · Tension pneumocephalus — which can result from air accumulation under pressure within the skull cavity — is a potentially fatal condition and may require emergency surgery. It is difficult to diagnose and treat; therefore, a thorough understanding of its cause, clinical manifestation, and management is required. Although this complication is uncommon, …

2024年6月4日 · Pneumocephalus, pneumoencephalus, intracranial pneumatocele or aerocele are all terms for air in the head, where it is not meant to be. It can be a normal consequence of brain surgery and is usually not a major thing, except were there is too much air, or when it ends up under tension. This condition has never come up in the exam until a relatively recent radiology …

2023年2月21日 · Pneumocephalus (plural: pneumocephali), also known as pneumocranium, pneumocrania, pneumatocephalus, and intracranial pneumatocele, refers to the presence of intracranial gas, and in the vast majority of cases, the gas is air. The term encompasse...

Iatrogenic Disease. David J. Birnbach MD, MPH, J. Sudharma Ranasinghe MD, FFARCSI, in Clinics in Perinatology, 2008 Pneumocephalus. Pneumocephalus, the introduction of air into the cranial cavity, is a rare complication typically associated with placement of an epidural anesthetic using the loss-of-resistance-to-air technique.The neurologic findings associated with …

Written by: Dr. Jacquie Jacob, University of Kentucky. Newcastle disease, also called ND or pneumoencephalitis, is caused by paramyxovirus.The highly contagious and lethal form of Newcastle disease is known as viscerotropic velogenic Newcastle disease or VVND. (The term viscerotropic indicates that the virus attacks the internal organs, velogenic indicates that the …
