Summary
Pulmonary sequestration, a congenital lung abnormality, can twist (torsion), causing severe chest and abdominal pain. This rare complication highlights the importance of considering unusual presentations of this condition.
Area of Science:
- Pulmonology
- Pediatric Surgery
- Congenital Abnormalities
Background:
- Pulmonary sequestration is a rare congenital lung malformation.
- It involves non-functional lung tissue with abnormal blood supply.
- Two main types exist: intralobar and extralobar.
Observation:
- An 11-year-old girl presented with acute abdominal and pleuritic chest pain.
- Imaging revealed an extralobar pulmonary sequestration.
- The sequestration had undergone torsion, a rare complication.
Findings:
- Extralobar pulmonary sequestration can present with acute abdominal pain due to torsion.
- Torsion of pulmonary sequestration is an uncommon but serious complication.
- The arterial supply typically arises from the descending aorta, and it lacks bronchial communication.
Implications:
- This case underscores the need for considering torsion in the differential diagnosis of acute abdominal and chest pain in children with pulmonary sequestration.
- Early recognition and surgical intervention are crucial for managing this complication.
- Further research into the mechanisms and predisposing factors for torsion in pulmonary sequestration may be warranted.

01:27Pneumothorax-II
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.

01:26Pneumothorax-I
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

01:08Pneumothorax II: Pathophysiology
Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...
01:19Pericarditis II: Clinical Features and Diagnostic Tests
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
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...
01:19Pulmonary Embolism I: Introduction
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
