Summary
Abdominal lymphatic malformations (LM) are rare cystic masses that can challenge diagnosis in young patients. Radiologists should consider LM in pediatric cystic abdominal masses, noting characteristic imaging findings.
Area of Science:
- Radiology
- Pediatric Imaging
- Vascular Anomalies
Background:
- Abdominal lymphatic malformations (LM) are rare focal lesions.
- They pose diagnostic challenges, particularly in pediatric patients.
- This review provides current information on LM manifestations and diagnosis.
Purpose of the Study:
- To offer updated information on various types of abdominal lymphatic malformations.
- To discuss associated syndromes and characteristic imaging features.
- To aid in the diagnosis of abdominal LM.
Main Methods:
- Literature review of abdominal lymphatic malformations.
- Analysis of clinical presentations and imaging features.
- Discussion of differential diagnoses and related syndromes.
Main Results:
- Abdominal LM often present as asymptomatic, incidental findings of thin-walled cystic masses.
- Cystic fluid can be proteinaceous, hemorrhagic, or infected.
- Key imaging features include lack of solid components and wall/septal enhancement, differentiating from other cystic diseases.
Conclusions:
- Abdominal LM should be considered in the differential diagnosis of cystic abdominal masses in children and young adults.
- Central conducting lymphatic anomaly (CCLA) and generalized lymphatic anomaly (GLA) are newly defined entities within the LM spectrum.

01:15Development of the Lymphatic System
2.1K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

01:25Abdominal Aorta
2.4K
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

17.7K
Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are...

01:28Functions of the Lymphatic and Immune System
6.9K
The lymphatic system plays a crucial role in bolstering our immune system. It consists of a network of lymphoid organs, lymph, and lymphatic vessels that provide structural and functional support in safeguarding the body against pathogens such as viruses and bacteria.
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...

01:16Lymphatic Vessels and Lymph Transport
23.4K
Lymphatic vessels, known as lymphatics, are crucial in transporting lymph from peripheral tissues to our venous system. This process begins with lymph entering through tiny capillaries that branch through tissues. These capillaries have unique features such as larger diameters, thinner walls, and a distinctive one-way valve system formed by overlapping endothelial cells.
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular...

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
