Abstract:
We have described the pre- and postgadolinium MR appearance in one case of acute myositis ossificans. The unenhanced sequences can be helpful in excluding malignancy, particularly when viewed serially. While use of gadolinium allowed primary sarcoma to be ruled out in this case, it was not useful in the exclusion of early abscess formation or necrotic metastasis.
Insights
Pre- and postgadolinium MRI can help differentiate acute myositis ossificans from malignancy. Serial imaging is key for diagnosis, though gadolinium contrast is not useful for detecting early abscess or necrotic metastasis.
Area of Science:
- Radiology
- Medical Imaging
- Musculoskeletal Imaging
Background:
- Acute myositis ossificans is a rare condition that can mimic other pathologies.
- Magnetic Resonance Imaging (MRI) is a crucial tool for diagnosing musculoskeletal conditions.
- Differentiating myositis ossificans from malignancy is critical for appropriate patient management.
Observation:
- This study details the pre- and postgadolinium MRI characteristics of acute myositis ossificans in a single case.
- Unenhanced MRI sequences were evaluated for their diagnostic utility.
- Gadolinium-enhanced MRI sequences were also analyzed for their effectiveness.
Findings:
- Unenhanced MRI sequences can be valuable in excluding malignancy, especially with serial imaging.
- Gadolinium administration aided in ruling out primary sarcoma in this specific case.
- However, gadolinium contrast was not effective in excluding early abscess formation or necrotic metastasis.
Implications:
- Serial unenhanced MRI is recommended for the diagnosis of acute myositis ossificans.
- MRI findings should be interpreted cautiously, considering the limitations of gadolinium contrast in certain differential diagnoses.
- Further research may be needed to establish definitive MRI criteria for differentiating myositis ossificans from other acute soft tissue lesions.

01:21Satellite Stem Cells and Muscular Dystrophy
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...
01:20Myasthenia Gravis: Overview and Treatment
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...

01:28Disorders of the Skeletal Muscle
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

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...

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...
01:22Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
