Pulmonary alveolar microlithiasis with an unusual radiological pattern
Abstract:
We present a case of pulmonary alveolar microlithiasis with an unusual radiological pattern in an an otherwise asymptomatic young woman. It was characterized by a reticulonodular pattern predominantly in the lower lung fields with Kerley B lines. The diagnosis was made by transbronchial lung biopsy. We found an otherwise asymptomatic brother with the same radiological pattern.

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...

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...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
