Summary
This study reviews male breast diseases, finding gynecomastia most common. Male breast cancer, while rare, is predominantly invasive ductal carcinoma, highlighting the need for vigilance.
Area of Science:
- Radiology and Pathology of Male Breast Diseases
Background:
- Male breast disease encompasses a range of benign and malignant conditions.
- Gynecomastia is the most common diagnosis, linked to diverse underlying causes.
Purpose of the Study:
- To present the spectrum of male breast diseases encountered over a 7-year period.
- To correlate radiological and histopathological findings for accurate diagnosis.
Main Methods:
- Retrospective review of male breast disease cases from 2007-2013.
- Correlation of imaging findings with histopathological diagnoses.
Main Results:
- Gynecomastia was the most frequent condition observed.
- Male breast malignancies, though infrequent, were analyzed.
- Invasive characteristics and infiltrating ductal carcinoma were the predominant findings in malignant cases.
Conclusions:
- Understanding the diverse presentations of male breast disease is crucial.
- Radiological and pathological correlation aids in diagnosing both benign and malignant conditions.
- Early consideration of male breast cancer, particularly invasive ductal carcinoma, is essential.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
661
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...

Radiological Investigation I: X-ray and CT
1.6K
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
927
Description
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...
