Summary
Eagle syndrome, characterized by neck pain due to styloid process elongation, can be triggered by acute parotitis. This case highlights a novel cause of this rare condition.
Area of Science:
- Otolaryngology
- Neurology
- Radiology
Background:
- Eagle syndrome is a condition involving cervicofacial pain and pharyngeal foreign body sensation, typically linked to styloid process elongation.
- It is commonly associated with prior tonsillectomy or trauma.
- This report details the first documented instance of Eagle syndrome precipitated by acute parotitis.
Observation:
- A 65-year-old woman presented with unilateral facial pain.
- Initial CT scans indicated acute parotitis, which resolved with antibiotic treatment.
- Persistent pain in the mandibular region, disproportionate to residual inflammation, prompted further review.
Findings:
- A subsequent CT scan revealed an asymmetrically elongated right styloid process.
- The patient's clinical presentation and imaging findings led to the diagnosis of acute parotitis-induced Eagle syndrome.
Implications:
- This case expands the known etiologies of Eagle syndrome.
- Physicians should consider Eagle syndrome in patients with atypical neck pain and elongated styloid processes.
- Prompt diagnosis is crucial as Eagle syndrome can lead to serious complications like carotid artery compression, syncope, and stroke.

Encephalitis l: Introduction
15
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology
22
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Arboviral Encephalitis
59
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Acute Pancreatitis I: Introduction
24
Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Acute Pancreatitis II: Pathophysiology
46
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
