Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary 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...

Pulmonary Embolism I: Introduction

Pulmonary 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...

Pulmonary Tuberculosis II

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Other Pulmonary Disorders

Other 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.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Pulmonary Edema II: Pathophysiology

Pulmonary Edema II: Pathophysiology

Pulmonary edema is the accumulation of fluid in the interstitial and alveolar spaces of the lungs, impairing gas exchange and oxygen delivery. It may be cardiogenic or noncardiogenic, but both reduce oxygenation and lung compliance.Cardiogenic Pulmonary EdemaCardiogenic edema results from increased hydrostatic pressure in pulmonary capillaries, usually due to left ventricular dysfunction from myocardial infarction, heart failure, or valvular disease. Ineffective cardiac pumping causes blood to...

Summary

A rare case of a large solitary pulmonary lymphangioma in a 49-year-old man caused significant symptoms. Surgical resection was successful, confirming the diagnosis through histopathology.

Area of Science:

Thoracic Surgery
Pulmonary Medicine
Surgical Pathology

Background:

Pulmonary lymphangiomas are rare benign tumors originating from lymphatic vessels within the lung.
Solitary lesions are exceptionally uncommon, presenting diagnostic and therapeutic challenges.

Observation:

A 49-year-old male presented with dyspnea and chest pain attributed to a rapidly growing mediastinal mass.
Imaging revealed an 18 x 12 cm cystic lesion in the posterior mediastinum.

Findings:

The resected lesion was histopathologically confirmed as a pulmonary cystic lymphangioma.
The tumor's large size and rapid growth were notable features.

Implications:

This case highlights the importance of considering rare diagnoses in the differential for mediastinal masses.
