Summary
Adnexal masses are common in pregnancy. Ultrasonography is the initial imaging test, but magnetic resonance imaging (MRI) aids in diagnosing ovarian lesions and differentiating benign from malignant tumors.
Area of Science:
- Radiology
- Obstetrics
- Gynecologic Imaging
Background:
- Adnexal masses are frequently encountered in pregnant patients.
- Advances in imaging technology lead to increased incidental discovery of adnexal masses during antenatal screening ultrasonography.
- Sonography is the primary imaging modality for evaluating adnexal masses.
Purpose of the Study:
- To discuss characteristic sonographic and MRI features of nonneoplastic and neoplastic ovarian lesions in gravid patients.
- To describe radiologic features that differentiate benign from malignant ovarian neoplasms.
- To highlight adnexal lesions specific to pregnancy that require consideration in the differential diagnosis.
Main Methods:
- Review of sonographic and MRI findings in adnexal masses during pregnancy.
- Correlation of imaging features with histopathologic diagnoses.
- Discussion of imaging characteristics that aid in distinguishing benign from malignant lesions.
Main Results:
- Sonography is the first-line imaging modality.
- Magnetic resonance imaging (MRI) provides critical diagnostic information, such as the presence of fat, aiding in teratoma diagnosis.
- Characteristic imaging features help distinguish various ovarian lesions, including those specific to pregnancy (e.g., hyperstimulated ovaries, theca lutein cysts, luteomas).
Conclusions:
- Sonography and MRI are essential tools for evaluating adnexal masses in pregnancy.
- MRI enhances diagnostic accuracy by characterizing mass composition and differentiating benign from malignant neoplasms.
- Consideration of pregnancy-specific adnexal lesions is crucial for accurate diagnosis.

01:19Appendicitis
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...
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...

01:18Uterus and Cervix
The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs of...

01:23Assessment of the Abdomen III: Palpation
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...
01:19Mitral Valve Prolapse III: Nursing Management
The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...
01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
