Summary
Acquired pulmonary stenosis is rare in adults and often caused by tumors. This case highlights non-Hodgkin
Area of Science:
- Cardiology
- Oncology
- Pulmonology
Background:
- Acquired pulmonary stenosis is uncommon in adults.
- Extrinsic compression from mediastinal tumors is a typical cause.
- Non-Hodgkin's lymphoma is a rare cause of extrinsic compression leading to pulmonary stenosis.
Observation:
- A patient with high-grade non-Hodgkin's lymphoma presented with progressive exertional dyspnea.
- Transthoracic echocardiography was utilized for diagnosis.
Findings:
- The patient's symptoms were attributed to extrinsic compression of the right pulmonary artery.
- High-grade non-Hodgkin's lymphoma was identified as the cause of the compression.
Implications:
- This case underscores the importance of considering lymphoma in the differential diagnosis of acquired pulmonary stenosis.
- Early diagnosis and management of lymphoma can alleviate pulmonary artery compression and improve patient outcomes.
- Transthoracic echocardiography is a valuable tool for diagnosing extrinsic compression of pulmonary arteries.

01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:30Pulmonary Hypertension: Classification and Pathogenesis
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

01:29Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
01:17Other Pulmonary Disorders
Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:25Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
