Insights

Cardiac hemangiomas are rare heart tumors. This case highlights incidental F-18 FDG PET/CT detection of a growing right ventricle hemangioma, successfully treated with surgery.

Area of Science:

  • Cardiology
  • Oncology
  • Nuclear Medicine

Background:

  • Cardiac hemangiomas are rare, benign heart tumors with unpredictable growth patterns.
  • Most cardiac hemangiomas are asymptomatic and discovered incidentally.
  • Diagnostic modalities include echocardiography, CT, MRI, and angiography, with limited F-18 FDG PET/CT data.

Purpose of the Study:

  • To report a rare case of cardiac hemangioma incidentally detected by F-18 FDG PET/CT.
  • To illustrate the potential role of serial F-18 FDG PET/CT in monitoring cardiac hemangioma growth.
  • To highlight the successful surgical management of a symptomatic cardiac hemangioma.

Main Methods:

  • Incidental detection of a cardiac mass during F-18 FDG PET/CT for thyroid cancer evaluation.
  • Serial F-18 FDG PET/CT scans to assess tumor size and metabolic activity.
  • Surgical resection of the cardiac hemangioma.

Main Results:

  • A cardiac hemangioma attached to the right ventricle was incidentally identified.
  • Serial F-18 FDG PET/CT demonstrated growth from 2.8 cm to 4.0 cm with mild F-18 FDG uptake.
  • The patient remained stable post-surgery without complications.

Conclusions:

  • F-18 FDG PET/CT can incidentally detect cardiac hemangiomas.
  • Serial F-18 FDG PET/CT may reveal tumor growth, aiding management decisions.
  • Surgical intervention can be effective for symptomatic cardiac hemangiomas.

Imaging 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...

Serial Position Effect01:03

Serial Position Effect

The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output01:22

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Cardiac Output I:Effect of Heart Rate on Cardiac Output01:19

Cardiac Output I:Effect of Heart Rate on Cardiac Output

Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
