Detailed Structure and Function of Lymph Nodes01:23

Detailed Structure and Function of Lymph Nodes

6.2K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Development of the Lymphatic System01:15

Development of the Lymphatic System

2.6K
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...

Lymphatic Vessels and Lymph Transport01:16

Lymphatic Vessels and Lymph Transport

24.5K
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...

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

10.2K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Area of Science:

  • Radiology
  • Medical Imaging
  • Head and Neck Imaging

Background:

  • Cervical node evaluation is a frequent challenge in radiology.
  • Intense enhancement of cervical lymph nodes on contrast-enhanced CT is uncommon.
  • Distinguishing the causes of intense nodal enhancement is crucial for diagnosis.

Purpose of the Study:

  • To provide a pictorial review of intensely enhancing neck nodes.
  • To discuss common etiologies of intense cervical lymph node enhancement.
  • To highlight radiologic features and differentiating points for diagnosis.

Main Methods:

  • Review of contrast-enhanced computed tomography (CT) scans.
  • Focus on cases demonstrating intense enhancement in cervical nodes.
  • Discussion of radiologic features and differential diagnoses.

Main Results:

  • Identification of specific conditions causing intense cervical lymph node enhancement.
  • Presentation of key imaging features for each condition.
  • Emphasis on differentiating features to aid radiologists.

Conclusions:

  • Radiologists must be aware of the limited differential for intensely enhancing cervical nodes.
  • Understanding characteristic imaging findings is essential for accurate diagnosis.
  • Exclusion of non-nodal mimics is also important in the diagnostic process.
