Summary
A rare middle mediastinum extralobar pulmonary sequestration was found in a 42-year-old female. Surgical excision via video-assisted thoracoscopy confirmed the diagnosis through histopathology.
Area of Science:
- Thoracic Surgery
- Pulmonary Medicine
- Diagnostic Imaging
Background:
- Extralobar pulmonary sequestration is a rare congenital lung malformation.
- Mediastinal masses can present diagnostic challenges, requiring detailed imaging and histopathology.
- Video-assisted thoracoscopic surgery (VATS) is a minimally invasive approach for thoracic procedures.
Observation:
- A 42-year-old female presented with an uncommon extralobar pulmonary sequestration.
- Chest computed tomography revealed a 6.5 × 2.7 × 2.0 cm middle mediastinal mass with cystic and solid components.
- The mass was located in the middle mediastinum.
Findings:
- Histopathologic examination confirmed the mass as an extralobar pulmonary sequestration.
- The sequestration featured a cystic cartilaginous wall lined with ciliated columnar epithelium.
- Edematous lung tissue was also identified within the sequestration.
Implications:
- This case highlights the importance of considering rare diagnoses for mediastinal masses.
- Video-assisted thoracoscopic surgery provides an effective minimally invasive treatment option for mediastinal pulmonary sequestration.
- Accurate histopathological analysis is crucial for definitive diagnosis and appropriate patient management.

1.1K
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...

01:13Pleura of the Lungs
8.8K
The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

01:17Gross Anatomy of the Lungs
5.6K
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

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:

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...

1.3K
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
