Summary
Malignant pleural neoplasms, including mesothelioma, are more common than benign types. Magnetic resonance (MR) imaging complements CT and PET/CT for evaluating these pleural tumors.
Area of Science:
- Oncology
- Radiology
- Thoracic Surgery
Background:
- The pleura can develop primary tumors or be affected by metastatic cancer.
- Primary pleural neoplasms constitute about 10% of all pleural tumors, with malignant types being more prevalent than benign ones.
- Malignant pleural mesothelioma and solitary fibrous tumor are the most frequent primary pleural neoplasms.
Purpose of the Study:
- To review the etiology, clinical presentation, and imaging characteristics of pleural neoplasms.
- To highlight the complementary role of magnetic resonance (MR) imaging in the evaluation and staging of pleural tumors.
- To provide a comprehensive overview of diagnostic approaches for pleural neoplasms.
Main Methods:
- Review of current literature on pleural neoplasms.
- Discussion of imaging modalities including computed tomography (CT), positron emission tomography (PET)/CT, and magnetic resonance (MR) imaging.
- Focus on the specific contributions of MR imaging in disease staging and patient evaluation.
Main Results:
- Pleural neoplasms encompass primary tumors and metastatic disease.
- Malignant lesions are more common, with mesothelioma being a key example.
- MR imaging offers valuable complementary information to CT and PET/CT for accurate staging.
Conclusions:
- Accurate diagnosis and staging of pleural neoplasms are crucial for patient management.
- Magnetic resonance imaging plays an essential role alongside other modalities in evaluating pleural tumors.
- Understanding the etiology and presentation aids in effective diagnostic imaging strategies.

4.5K
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
Clinical Manifestations:

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...
