Which of the following conditions can cause a hiatal hernia?

What are the four types of hiatal hernias?
Some divide them into four types: type 1: sliding hiatal hernia (~95%) type 2: paraesophageal hiatal hernia with the gastro-esophageal junction in a normal position. type 3: mixed or compound type, paraesophageal hiatal hernia with displaced gastro-esophageal junction.
Where is the GE junction?
The lower part of the esophagus that connects to the stomach is called the gastroesophageal (GE) junction. A special ring of muscle near the GE junction, called the lower esophageal sphincter, controls the movement of food from the esophagus into the stomach.
Which client is at highest risk of developing a hiatal hernia?
Aging: Overall, the chances of having a hiatal hernia increase as you get older. The diaphragmatic muscles naturally become weaker and more flexible with advancing age, and, as you get older, you are more likely to experience the risk factors for hiatal hernia.

CT partial-to-complete opacification of the mastoid air cells, which is non-specific but supportive of incipient mastoiditis in the appropriate clinical setting erosion of mastoid air cell bony septa, which establishes the diagnosis of coalescent mastoiditis
Does mastoid fluid on imaging change the diagnosis of mastoiditis?
The mere presence of mastoid fluid on imaging, however, does not change the management of otherwise uncomplicated acute otitis media. Thus, many clinicians reserve the diagnosis for when there are clinical signs or symptoms of inflammation involving the mastoid.
