Pyloric Obstruction

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...

Esophageal Achalasia

Esophageal Achalasia

Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...

Bulimia Nervosa

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Deglutition

Deglutition

Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

Upper GI Series: Barium Swallow

Upper GI Series: Barium Swallow

The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube through...

Summary

This summary is machine-generated.

An elderly woman experienced bilateral red eyes due to a carotid-cavernous sinus fistula. This rare condition, confirmed by CT perfusion, caused vision loss and eye movement issues.

Area of Science:

Ophthalmology
Neurology
Radiology

Background:

Carotid-cavernous sinus fistulas (CCSF) are abnormal connections between the carotid artery and the cavernous sinus.
CCSF can present with varied ocular and neurological symptoms, often mimicking other orbital pathologies.

Observation:

An 85-year-old female presented with bilateral red eyes, reduced visual acuity, episcleral congestion, iris hyperemia, and pigment epithelium detachment.
Ophthalmologic examination revealed impaired ocular motility and left abducens nerve paresis.
Magnetic resonance imaging (MRI) of the cerebrum was inconclusive for the diagnosis.

Findings:

Computed tomographic (CT) perfusion study confirmed the diagnosis of carotid-cavernous sinus fistula.
The CT perfusion study was crucial in identifying the vascular anomaly despite negative MRI findings.

Implications:

Early and accurate diagnosis of CCSF is vital for preventing vision loss and neurological complications.
CT perfusion imaging represents a valuable tool in diagnosing CCSF, especially when conventional MRI is non-diagnostic.
This case highlights the importance of considering CCSF in the differential diagnosis of bilateral red eye with ophthalmoplegia.
