Summary
This case report details two instances of sarcoidosis affecting the spine and sternum. Advanced imaging like CT, MRI, and PET/CT proved crucial in diagnosing this rare bone manifestation of sarcoidosis.
Area of Science:
- Radiology
- Oncology
- Rheumatology
Background:
- Sarcoidosis is a systemic disease with diverse manifestations, bone involvement occurring in 1-13% of cases.
- Vertebral and sternal involvement in sarcoidosis are exceptionally rare.
- Bone sarcoidosis can present as lytic, sclerotic, or mixed lesions.
Observation:
- Two patients presented with sarcoidosis involving the spine and sternum.
- One patient experienced diffuse bone pain; the other was asymptomatic.
- Imaging included radiography, CT, MRI, and FDG-PET/CT.
Findings:
- Radiographic, CT, MRI, and PET/CT revealed diffuse spinal involvement and sternal lytic lesions.
- Histopathology confirmed typical bone sarcoidosis in both patients.
- Both patients showed clinical and biological improvement with corticosteroid treatment.
Implications:
- CT, MRI, and FDG-PET/CT are valuable for diagnosing diffuse spinal sarcoidosis.
- This report highlights an unusual presentation of sarcoidosis with sternal lytic lesions.
- Early diagnosis and treatment of bone sarcoidosis can lead to improved outcomes.

01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:19Pericarditis 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...
01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
01:27Myocarditis 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...
