An Unusual ECG Finding during Adenosine Stress Myocardial Perfusion Imaging.
Indian J Nucl Med
November 2024
Department of Cardiology, Postgraduate Institute of Medical Education and Research, Chandigarh, India.
Adenosine is extensively utilized in myocardial stress perfusion imaging for the detection and risk stratification of coronary artery disease. It has a well-established safety profile. The majority of the undesirable effects experienced during adenosine infusion are transient (owing to its brief half-life of ~10 s) and arise from the stimulation of receptors in the atrio-ventricular (AV) node (AV block) and bronchial smooth muscles (bronchospasm).

Article Synopsis
- The text discusses a rare case of a 38-year-old female with hypertrophic obstructive cardiomyopathy, experiencing severe angina due to multiple coronary microfistulae and a myocardial bridge.
- Diagnosis was confirmed through various tests, including an electrocardiogram and CT coronary angiography, which revealed specific abnormalities like left ventricular enlargement and a left anterior descending artery myocardial bridge.
- The conclusion highlights that in cases of hypertrophic obstructive cardiomyopathy, angina may result from unusual factors like coronary artery fistulae or myocardial bridges, and CT coronary angiography is recommended for effective screening and treatment planning.

Primary intracranial sarcomas constitute a rare group of tumors, with the most common types described in the literature being chondrosarcoma and fibrosarcoma. Dedifferentiated liposarcoma (DDLS) is a high-grade sarcoma that sometimes metastasizes to the brain. However, a primary intracranial DDLS is exceedingly rare.
