Summary
COVID-19-associated shoulder girdle calcific myositis is a rare complication. Early recognition of this condition can improve patient outcomes and reduce long-term morbidity.
Area of Science:
- Musculoskeletal Radiology
- Infectious Diseases
- Rheumatology
Background:
- COVID-19 (Coronavirus Disease 2019) has been associated with various extrapulmonary manifestations.
- Shoulder girdle calcific myositis is an uncommon condition characterized by inflammation and calcification of the shoulder girdle muscles.
Purpose of the Study:
- To determine the prevalence of shoulder girdle calcific myositis in patients with COVID-19.
- To describe the radiological features of this condition.
- To evaluate the clinical sequelae and patient outcomes.
Main Methods:
- Retrospective review of CT pulmonary angiogram studies from April-May 2020, January 2021, and July 2021.
- Identification of patients with COVID-19 and shoulder girdle calcific myositis.
- Review of electronic patient records for demographics, inflammatory markers, and proning history.
Main Results:
- The overall prevalence of COVID-19-associated shoulder girdle calcific myositis was 1.3%.
- Prevalence varied across different COVID-19 waves: 2.8% (Wave 1), 0.8% (Wave 2), and 2.7% (Wave 3).
- The subscapularis muscle was the most common site affected by calcific myositis.
Conclusions:
- COVID-19-associated shoulder girdle calcific myositis is a rare extrapulmonary manifestation of COVID-19.
- Increased awareness and early diagnosis are crucial for reducing patient morbidity and improving functional outcomes.

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

01:23Muscles of the Shoulder
6.0K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

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...

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
