Summary
Adrenal gland enlargement can stem from various noncancerous conditions like hyperplasia or infection. Accurate CT imaging is crucial for diagnosing these adrenal disorders and preventing serious complications.
Area of Science:
- Radiology
- Endocrinology
- Pathology
Background:
- The adrenal gland exhibits diverse morphological changes due to nonneoplastic conditions.
- Conditions include hyperplasia, hemorrhage, infection, and cystic masses, each presenting unique imaging characteristics.
Purpose of the Study:
- To describe nonneoplastic adrenal gland disorders.
- To illustrate representative computed tomography (CT) findings for each condition.
Main Methods:
- Review of CT imaging findings in patients with nonneoplastic adrenal pathology.
- Correlation of imaging features with histopathological diagnoses where available.
Main Results:
- Detailed descriptions and representative CT images are provided for adrenal hyperplasia, hemorrhage, infection, and cystic lesions.
- Specific imaging patterns associated with each entity are highlighted.
Conclusions:
- Accurate characterization of adrenal lesions on CT is vital for clinical management.
- Distinguishing between entities like infection/hemorrhage and benign cysts is crucial for patient outcomes and avoiding Addisonian crisis.

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
01:27Imaging Studies III: Computed Tomography
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...

01:21Imaging Studies for Cardiovascular System IV: CMRI
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
01:30Radiological Investigation I: X-ray and CT
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 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...
