Resumen
La carcinomatosis linfangítica pulmonar (CLP) es un cáncer metastásico raro y agresivo. El diagnóstico temprano mediante biopsia es crucial, ya que las tomografías computarizadas pueden simular otras enfermedades pulmonares, lo que retrasa el tratamiento.
Área de la Ciencia:
- Oncología; Neumología; Radiología
Sus antecedentes:
- La carcinomatosis linfangítica pulmonar (CLP) es un cáncer metastásico raro y agresivo.; Implica émbolos tumorales que se diseminan a través del sistema linfático pulmonar y se infiltran en el intersticio.; Los hallazgos radiológicos pueden simular enfermedades pulmonares intersticiales o infecciones, lo que puede retrasar el diagnóstico.
Objetivo del estudio:
- Describir un caso de CLP en una paciente con cáncer de mama metastásico.; Destacar los desafíos en el diagnóstico de la CLP debido a hallazgos inespecíficos en la TC.; Enfatizar la importancia del diagnóstico temprano y la biopsia.
Principales métodos:
- Presentación de un caso de una mujer de mediana edad con disnea y tos progresivas.; Las tomografías computarizadas torácicas revelaron consolidación difusa en parches del espacio aéreo y engrosamiento septal interlobulillar.; La broncoscopia con biopsia confirmó carcinoma de mama HER2-positivo con diseminación linfangítica metastásica.
Principales resultados:
- La paciente presentó síntomas que simulaban neumonía pero no respondió al tratamiento empírico.; Los hallazgos de la TC no fueron específicos, mostrando consolidación y engrosamiento septal.; La biopsia confirmó carcinomatosis linfangítica pulmonar (CLP) por cáncer de mama metastásico.
Conclusiones:
- Los hallazgos atípicos de la TC de la CLP pueden simular enfermedades pulmonares intersticiales.; La CLP es agresiva y a menudo se diagnostica en una etapa tardía.; La alta sospecha clínica y la biopsia temprana de tejido son esenciales para el diagnóstico definitivo y el manejo oportuno.

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...

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, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

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.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
377
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...
