Incidental findings of acute myocardial infarction detected during ECG-gated and nongated thoracic CTA: A report of four cases

Worldwide, myocardial infarction is a leading cause of mortality and disability. The phrase ``myocardial infarction'' refers to ischemia, which is the outcome of an imbalance in perfusion between supply and demand and results in the death of cardiac myocytes Myocardial ischemia is often diagnosed based on the patient's medical history and electrocardiogram (ECG) findings. Potential ischemic symptoms include a variety of chest, upper extremity, jaw, or epigastric pain or discomfort that typically lasts at least 20 minutes, is diffuse, not positional, not localized, not dependent on movement of the area, and may be accompanied by syncope, dyspnea, or nausea. These symptoms can occur at rest or after physical activity. These symptoms may be mistaken for other conditions since they are not specific to myocardial ischemia. Radiologists play a crucial role in this scenario since imaging is increasingly being used to identify and categorize these individuals. We report 4 cases of myocardial infarction presenting without chest pain and discovered incidentally during imaging tests.

Radiological findings in Erdheim Chester disease: A very rare multisistemic disease

Erdheim-Chester disease is an uncommon non-Langerhans cell histiocytosis affecting multiple systems. There is limited knowledge on the imaging capabilities of this disease. We present an extremely rare case of Erdheim-Chester illness in a 67-year-old man with multisystem involvement, including the cardiovascular system, skeleton, retroperitoneum (renal and adrenal infiltration) and the neurologic system. The involvement of the various organs was thoroughly assessed using multimodal imaging modalities such as computed tomography, magnetic resonance imaging, positron emission tomography and bone scintigraphy. Erdheim-Chester illness was revealed by a bone biopsy. Especially when there is cardiac and cerebral involvement, Erdheim-Chester illness is a rare condition with a poor prognosis. Knowing the imaging characteristics of Erdheim-Chester disease may be helpful in understanding the radiological results of many organs affected by the disease as described and discussed in the current case report.
