Brain Abscess l: Introduction

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Appendicitis

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

Cryptococcal Meningitis

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Cranial Bones: Lateral View

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

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...

Cerebral Edema l: Introduction

Cerebral Edema l: Introduction

Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...

Summary

Omental cysts are rare, and their imaging features are not well understood. This case highlights key computed tomography and angiography findings of an omental pseudocyst in a young man.

Area of Science:

Gastroenterology
Radiology
Surgical Pathology

Background:

Omental cysts are rare intra-abdominal cystic lesions, often presenting diagnostic challenges due to limited understanding of their imaging characteristics.
Accurate pre-operative diagnosis is crucial for appropriate management and surgical planning.

Observation:

A 29-year-old male presented with an omental cyst.
Diagnostic imaging included contrasted computed tomography (CT) and angiography.
CT revealed characteristic thin ring-like enhancement of the cyst wall.

Findings:

Angiography demonstrated that the feeding arteries originated from the right gastroepiploic artery.
Surgical excision was performed.
Pathological examination confirmed the diagnosis of an omental pseudocyst.

Implications:

This case contributes to the understanding of omental cyst imaging features, particularly the value of CT and angiography in diagnosis.
Recognizing these specific vascular and enhancement patterns can aid radiologists and surgeons in differentiating omental cysts from other abdominal masses.
Further case reports and studies are needed to fully elucidate the spectrum of imaging findings for omental cysts.
