Summary
Renal angiomyolipomas can rupture and bleed, posing a significant risk. CT angiography is crucial for diagnosing these ruptured tumors and guiding emergent endovascular intervention.
Area of Science:
- Urology
- Radiology
- Vascular Surgery
Background:
- Renal angiomyolipomas (AMLs) are benign tumors containing fat, smooth muscle, and blood vessels.
- These tumors carry a substantial risk of spontaneous hemorrhage, often due to abnormal vasculature and pseudoaneurysms.
Observation:
- Three cases of ruptured renal AMLs with significant pseudoaneurysm formation are presented.
- Diagnosis was established using computed tomography angiography (CTA).
Findings:
- CTA accurately identified the ruptured AMLs and associated pseudoaneurysms in all three emergency cases.
- CTA facilitated timely and effective emergent endovascular intervention to control hemorrhage.
Implications:
- CT angiography is proposed as the preferred diagnostic imaging modality for ruptured renal AMLs, especially in emergency settings.
- Prompt diagnosis via CTA enables life-saving endovascular treatment, improving patient outcomes.

01:19Imaging Studies VII: Vascular Imaging
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

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...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
