Insights

Radiologists can identify potential COVID-19 cases using chest imaging, even in patients with non-respiratory symptoms. This aids early quarantine and limits disease spread.

Area of Science:

  • Radiology
  • Infectious Diseases
  • Pulmonology

Background:

  • Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, presents diagnostic challenges due to limited testing availability.
  • Typical COVID-19 imaging findings include ground-glass opacities, often in basal and peripheral lung zones.

Observation:

  • Three patients with non-respiratory symptoms underwent CT scans including portions of the lungs.
  • Suspicious imaging findings prompted COVID-19 testing in all three patients.

Findings:

  • All three patients tested positive for COVID-19.
  • One patient presented with the novel co-occurrence of COVID-19 and intraparenchymal hemorrhage.

Implications:

  • CT imaging of the chest, even during non-respiratory evaluations, can reveal COVID-19.
  • Early identification through imaging facilitates timely quarantine, reducing further transmission.
  • This approach is crucial when COVID-19 testing is limited.

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pericarditis II: Clinical Features and Diagnostic Tests

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
