Summary
Peritoneal inclusion cysts (PICs) are more common than previously thought, particularly in women. Understanding their imaging features can help avoid misdiagnosis and inappropriate treatment.
Area of Science:
- Radiology
- Pathology
- Gynecologic Imaging
Background:
- Peritoneal inclusion cysts (PICs) are fluid collections within the peritoneum.
- Their frequency and typical imaging findings are not well-established in the literature.
Purpose of the Study:
- To determine the frequency of patient characteristics, causative factors, and imaging features of pathology-proven peritoneal inclusion cysts (PICs).
Main Methods:
- Retrospective review of 228 patients with pathology-proven PICs over 19 years.
- Descriptive statistics for demographic and clinical data.
- Analysis of imaging features on CT, MRI, and/or US in 77 pre-operative studies.
Main Results:
- PICs affect a wide age range (18-89 years), predominantly women (82.5%).
- A history of peritoneal insult is common (70.6%).
- Imaging varies from simple to complex fluid collections; thick walls, nodularity, or solid components exclude PICs.
Conclusions:
- PICs are more prevalent than previously reported.
- Recognizing patient demographics and characteristic imaging findings can prevent misdiagnosis and overly aggressive management.

01:22Imaging Studies VI: Voiding Cystourethrography and Cystography
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
01:28Urologic Endoscopic Procedure: Cystoscopic Examination
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
01:22Imaging Studies V: Intravenous Urography and Retrograde Pyelography
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

01:22Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

01:27Imaging Studies III: Computed Tomography
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
