Summary
Pulmonary sequestration, a rare lung malformation, can present as a retroperitoneal mass. This case highlights successful laparoscopic excision of an 11.3-cm extralobar sequestration.
Area of Science:
- Medical Science
- Surgical Oncology
- Radiology
Background:
- Pulmonary sequestration is a congenital lung malformation characterized by non-functional lung tissue with an abnormal systemic arterial supply.
- Extralobar pulmonary sequestration is rarer than intralobar, often presenting as a discrete mass.
- Diagnosis typically involves imaging modalities to delineate the sequestration and its vascular supply.
Observation:
- A 40-year-old male presented with a large, 11.3-cm retroperitoneal mass.
- Preoperative imaging confirmed a multiloculated cystic lesion consistent with extralobar pulmonary sequestration.
- The patient underwent a laparoscopic retroperitoneal mass excision.
Findings:
- The laparoscopic approach facilitated complete excision of the retroperitoneal mass.
- Histopathological analysis confirmed the diagnosis of extralobar pulmonary sequestration.
- The patient experienced an uneventful recovery post-surgery.
Implications:
- This case demonstrates the feasibility and efficacy of minimally invasive surgery for large extralobar pulmonary sequestration presenting outside the thorax.
- Laparoscopic retroperitoneal mass excision can be a safe and effective treatment option.
- Highlights the importance of considering extralobar pulmonary sequestration in the differential diagnosis of retroperitoneal masses.

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:

01:26Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
01:27Adrenal Gland Disorders
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

01:18Pulmonary 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...
01:17Anatomy of the Adrenal Glands
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
The adrenal gland comprises two distinct regions...
